2. What Is the HINO Universal Joint?
เดอะ HINO Universal Joint is a cross-and-bearing assembly (also called a Cardan joint or U-joint) designed to transmit rotational torque between two shafts that are not perfectly aligned. In HINO medium and heavy-duty trucks, the propeller shaft connects the transmission output to the rear axle differential — and neither of those components sits on exactly the same geometric axis. The GUH series bridges that angular difference while maintaining continuous, smooth power delivery at all vehicle operating speeds.
Each unit in the GUH range is identified by a part number that encodes its key dimensions: journal diameter (D), overall assembly length (L), and configuration type (A, I, or G). Cross references to original HINO part numbers, as well as interchange references for KOYO and MATSUBA aftermarket equivalents, are provided in the specification table below, making it straightforward to verify fitment against your vehicle’s existing parts list or workshop manual. The range spans journal diameters from 20 mm (GUH69) up to 58.03 mm (GUH75), covering virtually the full spectrum of HINO truck driveshaft applications in the Colombian and Latin American commercial vehicle market.
As a direct-fit replacement product, the EP HINO GUH Series Universal Joint eliminates the fitment uncertainty that comes with generic cross-and-bearing kits. Each variant is dimensionally verified against the original equipment specification, so installation is a straightforward drop-in procedure using standard workshop tools. For fleet maintenance managers in Colombia who operate mixed HINO fleets — from light urban delivery trucks to heavy multi-axle prime movers — having access to a consolidated GUH series catalog with confirmed OEM cross-references significantly reduces procurement lead time and minimises vehicle off-road time.
3. Five Key Advantages of the EP HINO Universal Joint
1. OEM-Referenced Dimensional Accuracy
Every HINO universal joint part number is cross-referenced to the original HINO part number, KOYO reference, and MATSUBA aftermarket designation. This multi-reference approach gives workshop technicians and parts counters multiple confirmation paths before installation, virtually eliminating the risk of incorrect fitment. Dimensional accuracy at the journal, bearing cup, and snap-ring grooves is held to tolerances consistent with OEM manufacture, ensuring that bearing preload and seal engagement are correct from the first installation.
2. Broad Application Coverage Across the GUH Range
With seventeen part numbers spanning journal diameters from 20 mm to 58.03 mm and assembly lengths from 58 mm to 175 mm, the GUH series covers HINO truck driveshaft applications from light-duty urban logistics vehicles through to heavy multi-axle highway trucks. This breadth means a single supplier relationship covers the driveline universal joint requirements of an entire mixed-specification HINO fleet, simplifying inventory management and warranty tracking for fleet operators across Colombia.
3. High-Grade Bearing Steel with Superior Fatigue Life
The needle roller bearing cups within each GUH joint are produced from high-carbon chromium bearing steel (equivalent to SAE 52100 / GCr15), heat-treated to achieve the hardness profile required for high-cycle driveshaft operation. The cross journal itself is forged from alloy structural steel, carburized and case-hardened to resist the combined bending, torsional, and impact loads that commercial truck driveshafts experience on Colombia’s varied road infrastructure — from smooth toll highways to unpaved rural access roads.
4. Sealed and Grease-Packed for Reduced Maintenance Intervals
GUH series joints are supplied pre-packed with high-temperature extreme-pressure grease and fitted with lip seals that retain lubricant while excluding water and particulate contamination. For vehicles operating on dusty unpaved routes common in Colombia’s Llanos and Andean mining access roads, effective sealing directly determines joint service life. Grease nipple provisions on applicable variants allow periodic re-lubrication at standard service intervals, extending operating life beyond what sealed-for-life units alone can achieve in severe-duty service.
5. One-Stop Driveline Supply — Universal Joint, Axle, and Wheel Hub
The GUH universal joint is part of a broader driveline component portfolio that includes axle shafts and wheel hub assemblies. Sourcing the complete driveline from one supplier ensures dimensional compatibility across the system, simplifies procurement documentation, and provides a single technical point of contact for warranty claims or technical queries. For Colombian fleet operators managing total cost of ownership, this one-stop approach reduces the administrative overhead of multi-supplier sourcing and improves parts traceability.
4. Universal Joint Working Principle
Understanding the function of a universal joint starts with the basic geometry of a Cardan cross joint. In a HINO truck driveshaft assembly, the transmission output yoke and the differential input yoke are connected by one or more propeller shaft sections, each terminated with a U-joint. The joint allows the shaft angle between these yokes to change continuously as the vehicle suspension moves — absorbing the angular displacement caused by chassis flex, road undulations, and load variations — while maintaining uninterrupted rotational drive.
The cross-and-bearing assembly at the heart of each HINO Universal Joint consists of a four-armed steel cross (the spider or trunnion), with each arm fitted into a precision needle-roller bearing cup that sits in the corresponding yoke bore. As the driveshaft rotates and the operating angle between input and output yokes changes, the cross pivots freely in two perpendicular planes simultaneously. This two-axis freedom is what defines the Cardan joint and distinguishes it from a simple flexible coupling. The result is that torque is transmitted continuously regardless of shaft angularity, up to the maximum operating angle for which the joint is rated — typically 7 to 12 degrees for automotive propeller shaft applications, depending on shaft speed and the torque load.
One characteristic of a single Cardan joint is that it introduces a cyclic velocity variation in the driven shaft when operating at any angle other than zero — the output shaft does not rotate at perfectly constant speed even when the input does. In HINO truck driveshaft design, this is mitigated by using two U-joints (one at each end of the propeller shaft) phased correctly so that the velocity variation introduced by one joint is cancelled out by the second. This phasing arrangement is why driveshaft yoke orientation matters during assembly — a misphased driveshaft produces vibration at twice driveshaft rotational frequency, which is a characteristic symptom of a driveshaft that has been incorrectly reassembled after universal joint replacement.
5. วัสดุและการก่อสร้าง
The cross journal (spider) of each HINO GUH Universal Joint is forged from medium-carbon alloy steel — typically equivalent to SAE 8620 or 20CrMnTi — then carburized and case-hardened to achieve a surface hardness of 58–62 HRC at a case depth appropriate for the journal diameter. Forging rather than casting the spider ensures a continuous grain structure aligned with the principal stress directions in each arm, which is critical for fatigue resistance under the alternating bending and torsional loads that truck driveshafts experience over their service life. Core hardness after heat treatment is maintained in the range of 30–38 HRC, providing the ductility needed to absorb road-induced shock loads without brittle fracture.
Bearing cups are deep-drawn from strip steel and through-hardened, then ground to final internal diameter tolerances that ensure correct needle roller complement preload. The needle rollers themselves are produced from high-carbon chromium steel (SAE 52100 equivalent), hardened and ground to DIN 5402 dimensional tolerances. This material and process combination gives the needle roller assembly the fatigue life needed for the high-cycle, high-load conditions of a commercial truck propeller shaft, where bearing elements may complete tens of millions of load cycles over the vehicle’s service life.
Sealing is achieved through lip-type elastomeric seals on each bearing cup, manufactured from nitrile rubber (NBR) compounds compatible with the standard EP grease fill. For GUH variants deployed in high-temperature environments — such as exhaust-adjacent driveshaft positions on certain HINO truck configurations — HNBR or fluoroelastomer (FKM) seal compounds are available on request. External surfaces of the spider and yokes are protected against corrosion during storage and transport by a zinc phosphate conversion coating with rust-preventive oil, which also provides a base for subsequent lubricant retention in service.
6. สถานการณ์การใช้งาน
เดอะ HINO Universal Joint series serves a wide range of commercial vehicle and industrial driveshaft applications. Below are the primary use cases where this product delivers consistent performance.
HINO Truck Propeller Shaft Drives
The primary application for the GUH series is the main propeller shaft assembly on HINO medium and heavy commercial trucks. In Colombia, HINO trucks are widely used for inter-city freight transport on routes such as Bogotá–Medellín, Bogotá–Cali, and the Carretera Panamericana corridor. The propeller shaft on these vehicles connects the gearbox output to the rear axle or transfer case, operating under continuous high-torque loading across a range of shaft angles that vary with vehicle laden weight and road camber. GUH joints in the 47 mm and 50 mm journal diameter range (GUH61 through GUH73) are the most commonly specified for these primary driveshaft positions.
Intermediate Shaft and Centre Bearing Assemblies
On HINO trucks with longer wheelbases — common in the heavy-duty tractor and tipper configurations used in Colombia’s mining and construction sectors — the driveshaft is split into two sections connected by a centre support bearing, with a U-joint at each end of each section. GUH joints at the intermediate shaft positions typically operate at lower angles but higher speeds than the rear axle joint, making bearing grease retention and radial play control the critical performance parameters. GUH60, GUH63, and GUH65 variants, with their mid-range journal diameters, are well matched to these intermediate positions.
Steering Column Universal Joints
Several GUH variants — particularly those with smaller journal diameters such as GUH03, GUH66, and GUH69 — find application in HINO truck steering column universal joints และ steering universal joint assemblies. The steering column on a commercial truck must accommodate a significant change in shaft angle between the steering wheel and the steering gear box, particularly in cab-over-engine layouts where the column must pass through or around the engine firewall. A steering column universal joint in this location must transmit steering torque with minimal play and no noise — requirements that the GUH precision-machined cross assembly meets effectively.
Agricultural and Construction Equipment
Beyond on-road truck applications, HINO universal joint cross-and-bearing kits from the GUH series are used in the power take-off (PTO) and auxiliary driveline systems of agricultural and construction machinery that uses HINO engines or HINO-origin drivetrain components. In Colombia’s agricultural zones — the coffee regions of Antioquia and Caldas, the sugar belt of the Cauca Valley, and the banana plantations of Urabá — field machinery frequently operates with HINO-sourced driveline components that require GUH-equivalent replacement joints during scheduled service overhauls.
Bus and Coach Driveshafts
HINO-powered buses and coaches operating in Colombia’s urban transit systems and intercity coach routes use propeller shaft U-joints from the same GUH dimensional series as the truck range. The passenger transport sector in Colombia — including Transmilenio-feeder routes in Bogotá and long-distance coaches on the main national highway network — represents a significant demand source for HINO Universal Joint replacements, where driveshaft reliability is directly tied to passenger safety and vehicle scheduling compliance under concession agreements.
7. Regulatory Compliance & Standards
Commercial vehicle driveline components, including universal joints, are subject to a layered framework of vehicle safety regulations and quality standards that vary by country. For buyers in Colombia and across Latin America, understanding this framework is an important part of sourcing decisions for safety-critical replacement parts.
Colombia — RUNT and Technical Vehicle Inspection (RTM): Under Colombian law, commercial vehicles must pass the Revisión Técnico-Mecánica y de Gases (RTM) at accredited inspection centers, governed by Decree 019 of 2012 and Ministerio de Transporte resolutions. Driveshaft universal joint condition is evaluated as part of the vehicle’s driveline inspection during RTM. Worn or failed U-joints that produce vibration, noise, or play in the driveshaft assembly can result in failed inspection and vehicle immobilization. Using OEM-equivalent replacement parts such as the GUH series supports successful RTM compliance and provides documentation traceability for fleet operators.
Colombia — Ministerio de Transporte and Road Safety: Resolution 4100 of 2004 and its updates establish maximum dimensions and weight limits for commercial vehicles in Colombia, and the Código Nacional de Tránsito Terrestre (Law 769 of 2002) establishes safety responsibilities for vehicle owners and operators. Maintaining driveline components including universal joint in car and truck applications in serviceable condition is an operator obligation under these frameworks. Failure to maintain driveshaft joints can also constitute a contributing factor in road accident liability under Colombian civil and criminal law.
European Union — Vehicle Regulation Framework: For HINO vehicles type-approved under EU Regulation 2018/858 (which replaced the former Directive 2007/46/EC), replacement parts used in repair must meet the dimensional and performance standards of the original equipment. The GUH series, being dimensionally cross-referenced to OEM HINO part numbers, satisfies this requirement. For the EU market, REACH Regulation (EC) 1907/2006 also applies to the materials and surface treatments used in these components.
United States — FMCSA Regulations: Under Federal Motor Carrier Safety Administration (FMCSA) regulations 49 CFR Part 393, commercial motor vehicles must be maintained in safe operational condition, including driveshaft and universal joint integrity. Section 393.93 specifically addresses seat and driveline requirements. U-joints showing excessive wear, cracking, or lubricant loss are cause for vehicle out-of-service orders under FMCSA inspection criteria.
ISO 9001 Quality Management: Our manufacturing operations comply with ISO 9001-aligned quality management systems, ensuring batch traceability, dimensional inspection against OEM reference dimensions, and documented material certifications for each GUH series production run.

9. Related Products — Complete Driveline System Supply
เอ universal joint truck driveshaft system is only as reliable as its weakest component. Beyond the U-joint itself, the yoke, axle shaft, and wheel hub assembly all contribute to overall driveline integrity and service life. We supply a complete range of HINO-compatible driveline components, allowing customers to source the entire system from one technically qualified supplier.
Axle Shafts
The rear axle shaft transmits drive torque from the differential side gear to the wheel hub, operating in close dimensional relationship with the final propeller shaft U-joint. When a GUH universal joint is replaced as part of a driveshaft overhaul, inspecting the axle shaft for wear at the spline engagement zone and the hub bearing seat is standard workshop practice. Our axle shaft range for HINO trucks ensures the same level of OEM-dimensional accuracy as the GUH joint series, making it straightforward to overhaul the complete driveline at one service event.
Wheel Hub Assemblies
At the outboard end of the driveline, the wheel hub assembly connects the axle shaft to the wheel and tyre, and in driven axle configurations it forms the load path for both drive torque and vehicle weight. Hub bearing preload, wheel stud condition, and hub runout all directly affect driveshaft operating angles and therefore the load cycles seen by the HINO GUH Universal Joint at the axle end of the propeller shaft. Sourcing wheel hub assemblies from the same range as your GUH joints ensures dimensional compatibility and simplifies parts traceability for fleet maintenance records.
คำถามที่พบบ่อย
Q1. What is a universal joint and what is its main function in a HINO truck driveshaft?
A universal joint — also called a U-joint, Cardan joint, or cross-and-bearing assembly — is a mechanical coupling that transmits rotational torque between two shafts operating at an angle to each other. In a HINO truck, the function of a universal joint in the driveshaft is to maintain continuous power delivery from the gearbox to the rear axle differential while accommodating the angular change that occurs as the suspension compresses and rebounds, and as the vehicle’s load changes. Without a functioning U-joint, torque transmission between the driveshaft sections would be impossible across any operating angle, and driveshaft vibration or failure would result.
Q2. How do I know when my HINO truck needs a universal joint replacement in Colombia’s operating conditions?
The most common symptoms of a worn HINO universal joint replacement need are: a clunk or metallic knock felt through the cab floor when engaging drive from a standstill; a rhythmic vibration that increases with vehicle speed and is felt most strongly in the 60–100 km/h range; grease contamination visible at the driveshaft yoke (indicating a failed bearing cup seal); and visible rust streaking from the bearing cups. On Colombian mountain roads where gradients are steep and vehicles carry heavy loads, U-joint wear accelerates compared to flat-road operating conditions. A physical inspection of the propeller shaft — checking for angular play in any direction at each joint — should be part of every scheduled service.
Q3. Which GUH part number is the correct HINO universal joint replacement for a HINO 500 series heavy truck rear driveshaft?
HINO 500 series trucks typically use 47 mm or 50 mm journal diameter U-joints on the main propeller shaft. GUH61 (47 mm × 124 mm, OEM 9-953-3401-01), GUH62 (47 mm × 138 mm, OEM 3-302-3403-01), GUH64 (50 mm × 159 mm, OEM 3-302-3403-06), and GUH73 (50 mm × 165 mm, OEM 37401-1021) are the most likely candidates. However, the exact part number depends on the specific model year, gearbox specification, and driveshaft configuration. We recommend confirming the original HINO part number from the vehicle workshop manual or driveshaft assembly drawing before ordering.
Q4. What are the different types of universal joints and which type does the HINO GUH series use?
The main types of universal joints used in commercial vehicles are: the Cardan (or cross) joint (the type used in the GUH series); the constant velocity (CV) joint, which eliminates the cyclic velocity variation of a single Cardan joint and is common in front-wheel-drive passenger cars and some 4WD front axle applications; the double Cardan (DC) joint, which achieves near-constant velocity output by combining two Cardan joints in series; and the Rzeppa and tripod designs used in lighter passenger car applications. The GUH series HINO universal joint uses the standard Cardan cross-and-bearing design, which is the dominant type for heavy commercial truck propeller shafts worldwide due to its high torque capacity, durability, and repairability.
Q5. What is the expected service life of a HINO GUH universal joint in heavy haulage truck operations on Colombian mountain highways?
In heavily loaded HINO trucks operating on Colombian Andean mountain routes — where grades of 8–12% are common and loaded vehicle weights regularly approach or exceed 35 tonnes GVW — propeller shaft U-joints typically require inspection at 80,000–120,000 km intervals and replacement at 200,000–350,000 km, depending on lubrication practices, driveshaft operating angles, and the severity of road surface conditions. Vehicles that regularly operate on unmaintained access roads to mining or agricultural sites may see considerably shorter intervals. Periodic re-lubrication via grease nipples (on GUH variants that include this provision) at every oil service interval significantly extends joint life on these demanding routes. This guidance is based on general field experience; always consult the HINO workshop manual for the specific service schedule applicable to your vehicle model.
Q6. How does the HINO GUH universal joint differ from a standard universal impact joint or steering column universal joint in terms of design and load capacity?
เดอะ universal impact joint terminology is sometimes used informally to refer to heavy-duty driveshaft U-joints that are designed to absorb short-duration torque spikes from vehicle launch events or road-induced shock loads. The GUH series propeller shaft joints are designed for this category of load, with forged alloy steel spiders and needle roller bearing assemblies that accommodate both continuous rated torque and short-term peak torques. A steering column universal joint, by contrast, operates at much lower torque levels but requires very low rotational friction and zero backlash to preserve steering feel and precision. GUH03, GUH66, and GUH69 — the small-journal-diameter variants in the GUH range — are dimensionally suited to steering column positions, whereas GUH61 through GUH75 are primary driveshaft components.
Q7. When is it necessary to replace the entire driveshaft assembly rather than just the universal joint during a maintenance overhaul on a HINO commercial truck?
Individual universal joint replacement is appropriate when the shaft tube itself shows no distortion, the yoke bores are within tolerance for the replacement cross dimensions, and there is no evidence of previous improper repairs (weld repairs to the tube, elongated yoke bores, or stripped snap ring grooves). However, a complete driveshaft replacement is recommended when: the tube shows visible bending or distortion; the yoke bore diameter is worn beyond the serviceable limit for the GUH bearing cup outer diameter; the slip spline is heavily worn or corroded; or the driveshaft has been involved in a significant impact event that may have introduced hidden structural damage. In Colombia’s mining and construction sectors, where trucks frequently operate over rough terrain with shock loading events, it is good practice to have a reconditioned spare shaft assembly available for rapid vehicle turnaround when the old shaft condition warrants replacement rather than repair.
