What Is the 1710 Universal Joint?
The 1710 universal joint from Jiukai 9K Driveshaft (part number 48.01) is manufactured to the identical dimensional standard as OEM cross kits used in Class 6-8 heavy trucks, linehaul tractor-trailers, and vocational mining equipment. Cap OD 48 mm (1.890″), snap-ring span 127 mm — the same numbers your factory yoke was bored for.
All three OEM references — Spicer 5-1710X, Dana 1710, and Moog — — share exactly the same SAE 1710 series dimensional envelope. Our Jiukai 48.01 is manufactured to the same standard and installs without modification into any yoke or flange originally engineered for those references. When you order from universaljoint.net, you receive a part whose every critical dimension has been independently verified against the SAE 1710 specification before leaving the production line.
Common applications for the 1710 series include Class 6-8 heavy trucks, linehaul tractor-trailers, and vocational mining equipment. Well-known vehicle platforms that use this cross kit include the Peterbilt 389, Kenworth T680, Freightliner Cascadia, Volvo VNL, Mack Anthem, among many others. The universal joint size chart above details every SAE series alongside our Jiukai model numbers for rapid identification.
Measure the cap outer diameter (A) and snap-ring span (B) on your existing joint. The 1710 series uses a 48 mm (1.890″) cap OD and a 127 mm span. If those figures do not match, visit the grease and maintenance guide to identify the correct series, or get a freight quote for direct assistance.
Key Features of the Jiukai 1710 Cross Kit
The journal cross is forged from Cr-Mo steel and heat-treated to a core hardness of HRC 28–35 with a case hardness of HRC 58–62. This dual-zone hardness profile is optimised for the competing demands of impact resistance and surface durability in rotating power-transfer applications.
Bearing caps are ground on a CNC cylindrical grinder to h6 tolerance, giving a +0 / −0.013 mm deviation across the cap OD. The result is a controlled interference fit in standard yoke bores that eliminates rotational play from the first revolution.
The absence of a needle cage allows the maximum number of rollers to occupy each bearing cup. More rollers sharing the same load means longer fatigue life under the bending stresses imposed at working angles, compared with caged-roller designs carrying fewer needles.
The 1/4-28 UNF Zerk fitting is positioned to remain accessible in the installed position, allowing re-greasing at scheduled intervals without driveshaft removal. This feature is particularly valuable on commercial vehicles where downtime directly costs revenue.
Black manganese phosphate coating provides 240-hour salt-fog resistance during transit and storage. The micro-porous phosphate layer also acts as an oil reservoir in the break-in period, reducing initial adhesive wear before the grease film is fully established.
Every batch is produced under a quality system certified to ISO 9001, ISO 14001, and TS/16949. CE marking demonstrates compliance with European machinery and safety directives. Written dimensional reports and material certifications are available on request.
1710 Universal Joint Dimensions vs Neighbouring Series
The 1480 universal joint below shows your series in context. The highlighted row is the 1710. Use cap OD (A) and span (B) together to positively identify any cross kit — a single dimension alone is insufficient because some series share one value while differing in the other.

Applications
The 1710 U-joint cross kit is the OEM specification for the following driveline positions and vehicle categories:
- ✓Class 6–8 linehaul tractor-trailer propshafts (Peterbilt, Kenworth, Freightliner, Volvo)
- ✓Tanker trucks — petroleum, chemical, and food-grade tankers
- ✓Refrigerated trailer tractor drivelines
- ✓Logging and timber-hauling truck driveshafts
- ✓Bulk cement and bulk powder tanker propshafts
- ✓Mining haul truck drivelines — medium-capacity surface mines
- ✓Class 8 fire-fighting tankers and heavy rescue vehicles
Snap Ring and Packaging
The 1710 series cross kit uses an external snap-ring (C-clip) with a groove width of 1.75 mm. Snap rings are included in every shipment. The ring seats in the groove on the outer face of the yoke bore and is the primary axial retention method for the bearing cap.
An inside-snap-ring variant (suffix -IC) is available for yokes whose ear design does not accommodate external retention. Contact [email protected] for availability and lead times on non-standard configurations.

1710 Universal Joint: Linehaul Performance and Preventive Maintenance
Class 6 to 8 linehaul tractor-trailers accumulate 150,000 to 250,000 km per year in North American and European long-haul service. The 1710 cross kit must consistently achieve 600,000 to 800,000 km between replacement events to remain cost-competitive against sealed-for-life alternatives. Reaching the upper end of this service life range depends primarily on two variables: maintaining the greasing interval at 30,000 to 50,000 km and ensuring that the driveshaft operating angle stays below fifteen degrees throughout the vehicle service life. Modern air-ride suspensions and low-profile fifth-wheel assemblies typically maintain operating angles below eight degrees on level terrain.
The 127 mm snap-ring span, the longest in any standard SAE series, provides geometric resistance to bending loads from banked road curves and crosswind forces on tankers and box trailers. This bending resistance is a function of geometry alone and cannot be replicated by substituting a harder steel in a narrower-span cross kit. A driveshaft separation at highway speed is one of the most dangerous mechanical failures a heavy truck can experience; preventive maintenance, including a visual driveshaft check at every PM service and Zerk greasing at the scheduled interval, virtually eliminates the risk.

1710 Universal Joint: Failure Warning Signs
A failing 1710 universal joint in a Class 6 to 8 linehaul truck typically provides 50,000 to 100,000 km of symptomatic warning before catastrophic failure, but the consequences of ignoring those symptoms in heavy truck service are severe. The initial sign is a vibration at cruising speed, often experienced by the driver as a steering-column shake at 90 to 100 km/h on smooth motorways. As the bearing clearance increases, the vibration broadens to a wider speed band and a clunk develops during throttle transitions when load changes direction through the driveshaft. Late-stage failure is a rapid progression from metal-to-metal grinding to yoke separation. Linehaul fleet PM protocols must include a driveshaft lash check at every service; any rotational lash above two degrees should trigger immediate scheduling for replacement at the next available shop opportunity.
Fleet Maintenance: 1710 Universal Joint Service Guide
For Class 6–8 linehaul operators, a disciplined 1710 U-joint maintenance programme is a direct cost-reduction measure. A failed cross kit in an over-the-road tractor causes an average 6–10 hours of roadside downtime plus towing costs. Inspect all 1710 cross kits at every PM service: push the driveshaft laterally at each yoke and check for cap movement. Any visible cap rock confirms bearing clearance has opened beyond the serviceable limit. Re-grease every 30,000–50,000 km with NLGI Grade 2 EP grease; if the previous greasing interval produced dry or discoloured purge, the cap seal has compromised and the cross kit should be replaced at the next available shop visit.
When fitting the Jiukai 48.01, use a heavy-duty hydraulic press. The 48 mm caps require significant force to seat past the bore chamfer; never hammer cap faces directly. Confirm 1.75 mm snap rings are fully seated in their grooves by measuring with a depth micrometer if necessary. Grease the Zerk immediately after installation, confirm purge at all four seals, then log the installation date and odometer for the next maintenance cycle.
Bulk Procurement of 1710 Universal Joints for Truck Fleets
Owner-operators and fleet managers running Class 6–8 linehaul equipment typically replace 1710 cross kits at 500,000–600,000 km depending on route type and maintenance discipline. Planning stock for a managed-maintenance programme requires a reliable supply chain partner. Jiukai ships ex-works from Haining with a 15–20 day production lead time and maintains a standing stock of the 48.01 for spot orders.
Volume pricing is available from 20 pieces upward, with progressive discounts at 50, 200, and 500 pieces. All shipments include a packing list, commercial invoice, and certificate of origin.
