EP-HS222-486 Series \u2014 MERCEDES BENZ Universal Joint<\/h2>\n

Heavy-Duty Automotive U-Joint \u00b7 FIG Type A & B \u00b7 GKN Cross-Reference \u00b7 OEM-Compatible Replacement<\/p>\n

The EP-HS222-486 Series\u00a0 covers a carefully selected group of MERCEDES BENZ Universal Joint sizes engineered specifically for Mercedes-Benz commercial vehicle applications. The series takes its name from two key GKN reference numbers \u2014 HS222 and HS486 \u2014 that represent the most frequently sourced sizes within the Mercedes-Benz heavy truck and bus driveline range. Across the full series, journal (trunnion) diameters run from \u03c628 mm (HS446) through \u03c657 mm (HS289), covering an extensive spread of torque ratings to match the demands placed on light vans, medium-duty trucks, heavy long-haul tractors, and municipal bus chassis.<\/p>\n

Each joint is manufactured to cross-reference directly against OEM Mercedes-Benz part numbers and GKN catalogue references, meaning that procurement teams working from workshop manuals or parts databases can confirm fitment quickly. The product is offered in two bearing configurations \u2014 FIG Type A (four plain round bearings with grooved cups) and FIG Type B (four grooved round bearings) \u2014 allowing selection of the most appropriate sealing and lubrication retention design for the operating environment.<\/p>\n<\/div>\n

2. What Is a Universal Joint?<\/h2>\n

A universal joint<\/strong> \u2014 commonly shortened to U-joint \u2014 is a mechanical coupling that connects two rotating shafts whose axes are not perfectly aligned, allowing torque to be transmitted across a variable angular offset. The joint consists of a central cross-shaped spider (trunnion), four bearing caps filled with needle rollers, and two yokes that attach to the respective shafts. When the shafts form an angle to each other, the spider pivots within the bearing cups, maintaining continuous torque transmission while accommodating that misalignment. This mechanism makes the universal joint an essential component in virtually every rear-wheel-drive and four-wheel-drive drivetrain, as the propeller shaft must flex dynamically as the vehicle suspension moves through its travel range.<\/p>\n

What is the main function of a universal joint? In the context of heavy commercial vehicles \u2014 trucks, buses, and the broad range of vehicles built on Mercedes-Benz platforms \u2014 the U-joint transfers engine torque from the gearbox output shaft through the prop shaft to the rear axle differential, all while absorbing the angular changes imposed by the suspension. Without a properly functioning MERCEDES BENZ Universal Joint<\/strong>, power delivery becomes erratic, vibration is transmitted into the cabin, and accelerated wear to the driveshaft, transmission output bearing, and differential input seal follows rapidly. Understanding this function is the starting point for any informed replacement decision.<\/p>\n

<\/div>\n<\/div>\n
\n

3. Universal Joint Working Principle<\/h2>\n

\u306e \u666e\u904d\u7684\u306a\u5171\u540c\u4f5c\u696d\u539f\u5247<\/strong> is based on the Cardan mechanism, named after the Italian mathematician Gerolamo Cardano. At the heart of every MERCEDES BENZ Universal Joint<\/strong> is the cross-spider: a precision-machined forging with four trunnion journals ground to tight dimensional tolerances. Each journal fits inside a bearing cap that contains a complement of needle rollers, lubricated at assembly with high-performance lithium or moly-grease and retained by a lip seal or a ground cup face that prevents contamination ingress.<\/p>\n

When torque is applied to the input yoke, it is transferred through the bearing caps and spider body to the output yoke, rotating the output shaft. Because the spider can pivot in both the fore-aft and lateral planes simultaneously, the joint accommodates angular misalignment in any direction within its designed working angle \u2014 typically up to 15\u00b0 for heavy commercial vehicle applications. One characteristic of single-Cardan U-joints to be aware of is velocity fluctuation: at operating angles greater than 3\u20135\u00b0, the output shaft speed fluctuates twice per revolution relative to the input. In a properly designed driveshaft assembly, this is corrected by phasing two U-joints in series at equal angles, which cancels the velocity variation and delivers smooth, constant rotational output to the axle.<\/p>\n<\/div>\n

<\/p>\n

\n

4. Five Key Product Advantages of MERCEDES BENZ Universal Joint<\/h2>\n
\n
\n

\u2460 Precise OEM Cross-Reference Compatibility<\/h3>\n

Every joint in the EP-HS222-486 series MERCEDES BENZ Universal Joint is dimensionally verified against both the GKN catalogue number and the corresponding Mercedes-Benz OEM part number. Journal diameter, cup outer diameter, cup depth, snap ring groove location, and overall assembled length are all held to tolerances that ensure direct drop-in fitment into OEM yokes. This removes any guesswork during installation and eliminates the risk of premature failure caused by dimensional mismatches \u2014 a critical advantage for fleet workshops and independent repair shops undertaking mercedes benz hs universal joint replacement<\/strong> in commercial service environments.<\/p>\n<\/div>\n

\n

\u2461 Premium Alloy Steel Spider Construction<\/h3>\n

The cross-spider is forged from high-quality alloy steel and subjected to a controlled heat treatment cycle that develops a hard, wear-resistant case over a tough, impact-absorbing core. This combination \u2014 typically a surface hardness of 58\u201362 HRC over a core hardness of 35\u201345 HRC \u2014 gives the journal surface long resistance against the micro-pitting and spalling that end service life in heavy truck U-joints. For routes through the Colombian Andes, the Llanos, or coastal regions where loads and road shocks vary dramatically, this metallurgical balance translates directly into longer intervals between mercedes benz universal joint replacement<\/strong> events.<\/p>\n<\/div>\n

\n

\u2462 Sealed Bearing System for Extended Service Life<\/h3>\n

All bearing caps are fitted with precision lip seals that prevent water, road salt, mud, and abrasive particles from entering the needle bearing assembly. In tropical and high-humidity environments such as Colombia’s Pacific coast and Amazon basin regions, this sealed design is particularly important: unsealed or inadequately sealed joints are the single most common cause of early U-joint failure in vehicles operating in wet conditions. The grease fill is selected for wide temperature stability, ensuring consistent viscosity and film thickness whether the vehicle is starting cold in Bogot\u00e1 at high altitude or running at full load in the tropical lowlands.<\/p>\n<\/div>\n

\n

\u2463 Full Series Coverage \u2014 \u03c628 mm to \u03c657 mm<\/h3>\n

The EP-HS222-486 MERCEDES BENZ Universal Joint range covers ten distinct GKN sizes from the small HS446 (\u03c628\u00d749) through the heavy-duty HS289 (\u03c657\u00d7152), addressing every position in the Mercedes-Benz driveline from light van to heavy-haul truck. Having a single supplier source for all sizes in the range simplifies procurement, reduces the number of supplier relationships that need to be maintained, and enables fleet workshops to rationalise their U-joint stock into a single catalogued product family. This is especially valuable for logistics companies and bus operators running diverse Mercedes-Benz fleets across Colombian cities and intercity routes.<\/p>\n<\/div>\n

\n

\u2464 Strict Quality Validation and Traceability<\/h3>\n

Each batch is tested for dimensional conformity, surface hardness, needle bearing radial play, and grease distribution before packaging. Traceability records link every production lot to raw material certificates and heat treatment charts, supporting the documentation requirements that arise when supplying to OEM Tier 1 assemblers, certified fleet operators, or government transport agencies. This level of quality process control gives maintenance managers confidence that the joint they are installing meets or exceeds the performance of the original component \u2014 not just in its initial specifications, but over the full expected service cycle. For transport operators in Colombia subject to Ministerio de Transporte (MinTransporte) vehicle safety compliance requirements, documented quality assurance is an important factor in component selection.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

 <\/p>\n

\n

5. Material & Manufacturing Process of MERCEDES BENZ Universal Joint<\/h2>\n

The cross-spider \u2014 the load-bearing heart of every MERCEDES BENZ Universal Joint<\/strong> \u2014 is forged from medium-high alloy steel, typically 20CrMnTi or an equivalent grade, selected for its combination of hardenability, toughness, and dimensional stability through the heat treatment cycle. The forging process eliminates internal voids and aligns the grain structure along the load path of each trunnion journal, giving the raw spider a fatigue resistance advantage over machined-from-bar alternatives. After rough machining, the journals are carburised and case-hardened to achieve a surface hardness of 58\u201362 HRC to a case depth of 0.8\u20131.2 mm, while the core retains a toughness of 35\u201345 HRC to absorb impact without cracking under shock loading.<\/p>\n

The bearing cups are deep-drawn from low-carbon steel strip, then case-hardened and finish-ground on the outer diameter to press-fit into the yoke bores with a controlled interference. Needle rollers are manufactured from bearing-grade 100Cr6 (52100) chromium steel, hardened to 62\u201366 HRC for maximum contact fatigue life. Yokes, where supplied, are forged from medium-carbon steel and normalised to provide the strength and machinability needed for precision bore work. All metallic surfaces exposed to the needle bearing contact zone are ground to a surface roughness of Ra 0.4 \u03bcm or better to ensure correct oil film formation and minimise running-in wear. The entire assembly is packed with NLGI Grade 2 lithium-complex or lithium-molybdenum grease rated for the temperature range expected across Colombian operating environments, from Bogot\u00e1’s high-altitude cool nights to the hot lowland routes of the Magdalena valley.<\/p>\n<\/div>\n

6. MERCEDES BENZ Universal Joint Application Scenarios<\/h2>\n

\u306e universal joint in car<\/strong> and commercial vehicle applications is one of the most widely distributed mechanical components in the automotive world. The EP-HS222-486 series MERCEDES BENZ Universal Joint is specifically matched to the torque ratings and dimensional requirements of Mercedes-Benz vehicle platforms, and the applications described below represent the primary deployment contexts where this series is sourced and installed.<\/p>\n

\n
\n

Heavy-Duty Truck Prop Shafts<\/h3>\n

Long-haul trucks operating the Bogot\u00e1\u2013Buenaventura, Bogot\u00e1\u2013Medell\u00edn, and Trans-Caribbean routes typically run Mercedes-Benz Actros or Axor platforms whose main prop shafts use HS272, HS282, HS284, or HS289 joints. These large-diameter MERCEDES BENZ Universal Joint<\/strong> units handle the high torque output of the OM 460 and OM 470 engine families across steep Andean gradients where combined grade resistance and payload tonnage place extreme cyclic stress on the driveline. The universal joint truck<\/strong> application in this context demands maximum fatigue life and sealed bearing retention.<\/p>\n<\/div>\n

\n

Urban & Intercity Bus Drivelines<\/h3>\n

Mercedes-Benz O500 and Marcopolo-bodied bus fleets serving Bogot\u00e1’s Transmilenio BRT network, Medell\u00edn’s intercity routes, and coastal city transit systems use MERCEDES BENZ Universal Joint<\/strong> models HS222, HS236, HS259, and HS260 in their propeller shafts and inter-axle shafts. Buses accumulate very high annual mileages in stop-start urban duty cycles that impose frequent torque reversals and high lateral joint angles at the axle end, accelerating wear relative to highway driving. The sealed bearing design and premium grease specification of the EP series directly address the elevated maintenance demands of bus fleet operations.<\/p>\n<\/div>\n

\n

Light Commercial Vans<\/h3>\n

Mercedes-Benz Sprinter and Vito vans \u2014 widely used by Colombian courier services, medical supply chains, and food distribution networks \u2014 use the smaller MERCEDES BENZ Universal Joint<\/strong> sizes in this series, particularly HS446 (\u03c628\u00d749) and HS222 (\u03c635\u00d796.8). In van applications, the prop shaft joint often operates at a relatively steep angle because of the low floor height and rear-drive configuration, meaning that correct joint phase angle and assembly alignment are important during universal joint replacement<\/strong> to avoid driveshaft vibration after the repair.<\/p>\n<\/div>\n

\n

Steering Column U-Joints<\/h3>\n

Beyond the prop shaft, Mercedes-Benz steering systems use \u30b9\u30c6\u30a2\u30ea\u30f3\u30b0\u30e6\u30cb\u30d0\u30fc\u30b5\u30eb\u30b8\u30e7\u30a4\u30f3\u30c8<\/strong> components in the intermediate shaft between the steering column and the rack-and-pinion or recirculating-ball steering gear. The MERCEDES BENZ Universal Joint<\/strong> used in steering columns operates at lower torques than prop shaft units but requires very low angular play (backlash) to preserve steering precision and prevent shimmy. The smaller joints in the EP MERCEDES BENZ Universal Joint series are dimensionally appropriate for these applications, and the tight manufacturing tolerances maintained ensure backlash values stay within OEM specifications.<\/p>\n<\/div>\n

\n

Agricultural & Construction Equipment<\/h3>\n

Mercedes-Benz power units are also found in a range of agricultural machinery and light construction equipment operating in Colombia’s coffee-growing regions of Antioquia and the Eje Cafetero, as well as construction sites in the oil and gas corridor near Barrancabermeja. In PTO-driven and vehicle-mounted applications, the MERCEDES BENZ Universal Joint<\/strong> models HS480 (\u03c638\u00d757 and \u03a644\u00d7124.85) and HS486 (\u03c642\u00d766.4) serve intermediate shaft positions where angular variation is higher and impact loading from rough terrain demands robust joint construction. Correct grease specification for high-pressure contact conditions is essential in these applications.<\/p>\n<\/div>\n

\n

Specialty & Emergency Vehicles<\/h3>\n

Fire trucks, ambulances, military vehicles, and armoured transport units built on Mercedes-Benz commercial chassis platforms are operated by Colombian government agencies and private security operators across the country. These vehicles are characterised by infrequent but operationally critical use \u2014 a MERCEDES BENZ Universal Joint<\/strong> failure in an emergency vehicle is never acceptable. The combination of premium alloy steel, controlled heat treatment, sealed bearings, and OEM-level dimensional verification makes the EP-HS222-486 MERCEDES BENZ Universal Joint series a reliable choice for these high-consequence applications where parts availability and known quality documentation matter most.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Automotive drivetrain components including the MERCEDES BENZ Universal Joint<\/strong> are subject to a layered set of standards spanning materials, dimensional accuracy, safety certification, and import\/customs compliance. Understanding this framework is important for procurement officers, fleet managers, and workshop owners in Colombia and across Latin America who need to ensure that the replacement parts they source meet legal and operational requirements.<\/p>\n

ISO\u898f\u683c\uff1a<\/strong> ISO 8653 covers the specification and acceptance testing of universal joints for automotive applications. ISO 9001 quality management system certification is relevant for the manufacturing facility level, ensuring that design controls, process controls, and inspection procedures are documented and consistently applied. Material testing standards such as ISO 6507 (Vickers hardness) and ISO 683-17 (heat-treatable steels) underpin the material verification processes applied to spider forgings and bearing cups.<\/p>\n

Colombia (MinTransporte \/ ICONTEC):<\/strong> In Colombia, the Ministerio de Transporte (MinTransporte) sets the technical requirements for vehicle roadworthiness through C\u00f3digo Nacional de Tr\u00e1nsito (Law 769\/2002) and complementary resolutions governing vehicle inspections (Revisi\u00f3n T\u00e9cnico-Vehicular, RTV). Driveshaft integrity \u2014 which depends on the condition of U-joints \u2014 is assessed during the periodic technical inspection. The ICONTEC standard NTC ISO 9001 provides the quality system reference that most Colombian government fleet suppliers are required to demonstrate. Replacement drivetrain parts must be traceable and meet the dimensional specifications of the OEM component being replaced.<\/p>\n

\u6b27\u5dde\u9023\u5408\uff1a<\/strong> Mercedes-Benz vehicles sold into the EU market are type-approved under EU Regulation 2018\/858 (replacing Directive 2007\/46\/EC), which governs vehicle safety and environmental performance. While individual components like U-joints do not carry standalone CE marking, their design and material specifications must satisfy the type-approval dossier maintained by Mercedes-Benz AG. Aftermarket replacement parts claiming OEM equivalency must meet the same dimensional and performance specifications as the first-fit component.<\/p>\n

United States (SAE\/ANSI):<\/strong> The Society of Automotive Engineers (SAE) publishes SAE J901 covering universal joints and driveshafts for commercial vehicles. ANSI\/AGMA standards for gear and coupling materials provide additional reference for the steel grades and heat treatment processes used in U-joint manufacture. These standards are referenced by US Tier 1 driveshaft manufacturers and are accepted as technical baselines by international fleet operators.<\/p>\n

Brazil (ABNT \/ DENATRAN):<\/strong> Brazil’s DENATRAN (now SENATRAN\/SENATRAN-SE) requires vehicle safety compliance testing, and Brazilian-registered Mercedes-Benz trucks operating across the Mercosur region including Colombia’s border crossings must maintain driveline components within OEM specification. ABNT NBR standards for automotive steel components and fasteners provide the Brazilian national reference framework.<\/p>\n<\/div>\n

A MERCEDES BENZ Universal Joint<\/strong> operates as part of a broader drivetrain assembly. Replacing the joint without checking the condition of the companion components \u2014 particularly the wheel hub unit and the axle shafts \u2014 risks returning a vehicle to service with undetected wear that will shorten the life of the new joint or cause a secondary failure shortly after. We supply the full range of Mercedes-Benz drivetrain components, giving fleet workshops and distributors a single procurement source for the entire driveline.<\/p>\n

The wheel hub unit carries the wheel bearing, ABS sensor ring (where fitted), and the hub flange that connects the axle shaft to the road wheel. On driven axles, the hub unit works in direct series with the driveshaft and U-joints \u2014 if the hub bearing develops play, the resulting angular misalignment at the axle stub increases the operating angle of the outboard U-joint, accelerating its wear. We supply complete automotive wheel bearing and hub unit assemblies for Mercedes-Benz front and rear axle applications, with OEM and aftermarket cross-references available.<\/p>\n

\"Wheel<\/div>\n<\/div>\n
\n

Axles & Axle Shafts<\/h3>\n

Rear axle half-shafts on Mercedes-Benz trucks and buses transmit final drive torque from the differential to the wheel hub flanges. Any fatigue crack, spline wear, or torsional damage to the axle shaft changes the dynamic load distribution on the adjacent U-joints and the differential output bearings. We source and supply replacement axle shafts for a range of Mercedes-Benz commercial vehicle axle types, manufactured to OEM dimensional specifications with spline form and hardness profiles matched to the original component. Pairing a new axle shaft with a fresh U-joint during a major driveline service is the most efficient way to reset the entire assembly’s fatigue life clock.<\/p>\n

\nQ1. What does a universal joint do on a Mercedes-Benz truck operating on Andean mountain routes in Colombia?<\/summary>\n
A universal joint on a Mercedes-Benz truck transmits torque from the gearbox through the propeller shaft to the rear axle differential while allowing the driveshaft to flex as the suspension moves over uneven terrain. On Andean routes with steep gradients, tight switchbacks, and variable road surfaces, this angular accommodation is constant and significant. Without a correctly functioning joint, torque delivery becomes uneven, and the resulting driveline vibration accelerates wear in the transmission output bearing, the driveshaft centre bearing, and the differential input seal.<\/div>\n<\/details>\n<\/div>\n

\nQ2. What are the common symptoms of a worn MERCEDES BENZ HS universal joint that needs replacement?<\/summary>\n
The most common mercedes benz hs universal joint symptoms<\/strong> include a clunking or knocking noise from the undercarriage when pulling away from a standstill, a vibration felt through the chassis or cab at specific road speeds, and in severe cases a squeaking or grinding noise during turning. If the joint has developed significant radial play, it may be possible to feel movement in the driveshaft when the vehicle is stationary and you rock it in gear. Any of these signs warrant immediate inspection, as a fully failed joint can cause complete driveshaft separation, which is a serious safety hazard.<\/div>\n<\/details>\n<\/div>\n

\nQ3. How do I identify which GKN model number corresponds to my Mercedes-Benz truck or bus driveshaft joint?<\/summary>\n
The most reliable method is to locate the Mercedes-Benz OEM part number from the vehicle’s parts catalogue (either through the EPOC\/WIS system or the dealer parts counter) and cross-reference it against our product table. If the OEM number matches a Mercedes number in the table above \u2014 for example, 304100431 corresponds to HS222 \u2014 you have the correct GKN reference. Alternatively, measuring the journal diameter and the overall length (snap ring to snap ring) of the removed joint and comparing against the SIZE column in the specifications table will confirm the correct size. If you are uncertain, contact us with the vehicle model, year, engine designation, and axle type, and our technical team will identify the correct part.<\/div>\n<\/details>\n<\/div>\n

\nQ4. What is the correct procedure for universal joint replacement on a Mercedes-Benz Actros propeller shaft?<\/summary>\n
Universal joint replacement<\/strong> on a Mercedes-Benz Actros prop shaft requires the driveshaft to be removed from the vehicle, the yoke flanges to be marked for correct reassembly phasing, and the old joint pressed out of the yokes using a hydraulic press or suitable U-joint removal tool. The new joint is pressed in, ensuring the bearing caps fully seat and the snap rings locate correctly in their grooves. It is important not to hammer the joint into position, as this can fracture the bearing cup or dislodge the needle rollers. After installation, the driveshaft should be balanced if the vehicle operates at highway speeds, as any imbalance introduced by the new joint will cause vibration. Torque the yoke bolts to Mercedes-Benz specification and check for free articulation before refitting.<\/div>\n<\/details>\n<\/div>\n

\nQ5. What are the different universal joint types used on Mercedes Benz vehicles, and how do FIG A and FIG B differ?<\/summary>\n
Universal joint types<\/strong> in the Mercedes-Benz range include the standard Cardan cross-joint (Hooke’s joint) in both FIG Type A and FIG Type B bearing configurations. FIG A uses four plain round bearing caps with grooved sealing faces \u2014 common in larger truck and bus driveshaft applications. FIG B uses four grooved round bearing caps with a slightly different sealing arrangement suited to applications where the joint operates at a wider angle range or where grease retention under high centrifugal force is a priority. It is essential to select the correct FIG type for the yoke design in the specific vehicle, as the bearing cap outer diameter and retention method differ between the two.<\/div>\n<\/details>\n<\/div>\n

\nQ6. Which Mercedes Benz universal joint models are most commonly needed for bus fleet maintenance in Bogot\u00e1 and Medell\u00edn?<\/summary>\n
For Mercedes-Benz bus platforms operating in Bogot\u00e1 and Medell\u00edn \u2014 principally the O500R\/RA, O500U, and O500M chassis \u2014 the most frequently replaced sizes are HS222 (\u03c635\u00d796.8, OEM 304100431), HS236 (\u03c638.03\u00d7105.6, OEM 304102031), HS259 (\u03c645\u00d7118.1, OEM 304102231), and HS260 (\u03c645\u00d7120.4, OEM 4100031\/3044100031). The HS272 series (\u03c648.05\u00d7125.8, series 286.33) is also commonly required on longer-wheelbase articulated bus variants. Fleet maintenance managers operating multiple buses should consider holding minimum stock levels of these sizes to avoid vehicle downtime during unplanned joint failures.<\/div>\n<\/details>\n<\/div>\n

\nQ7. How does a steering universal joint on a Mercedes-Benz van differ from a driveshaft U-joint, and when should it be replaced?<\/summary>\n
A \u30b9\u30c6\u30a2\u30ea\u30f3\u30b0\u30b3\u30e9\u30e0\u30e6\u30cb\u30d0\u30fc\u30b5\u30eb\u30b8\u30e7\u30a4\u30f3\u30c8<\/strong> on a Mercedes-Benz van \u2014 such as the Sprinter \u2014 operates at much lower torques than a prop shaft joint but requires extremely tight rotational play (typically less than 1.0\u00b0 total backlash) to prevent vague or imprecise steering feel. A worn steering U-joint typically manifests as steering wheel wobble at low speeds, a slight knock when changing steering direction, or a notchy feel through the steering wheel at certain lock angles. Because the steering joint directly affects vehicle control, it should be replaced at the first sign of play \u2014 delay is not advisable. Installation requires careful alignment of the steering column shaft and intermediate shaft to avoid binding through the full lock-to-lock range.<\/div>\n<\/details>\n<\/div>\n<\/div>\n<\/div>\n
