5-675X Universal Joint 49.2×154.8 mm | 1710 Half Round M675X
Description
5-675X universal joint is a heavy-duty greaseable cross-bearing kit for Spicer 1710 Series half-round driveline assemblies. Dana’s nominal specifications list 49.225 mm bearing cup diameter and 154.788 mm length on both axes. This combination uses bearing-plate caps on one axis and plain round caps on the other, so it should not be confused with a standard full-round 1710 joint.
The photographed 5-675X universal joint kit contains one cross with four installed bearing cups, two retaining straps, two locking or bearing plates, mounting bolts and side-mounted grease fittings.
Product Features
Designed for medium- and heavy-duty commercial drivelines, the 5-675X universal joint combines a robust steel cross with serviceable lubrication and mixed bearing-plate x round cap construction. The 1710 half-round layout provides positive mechanical retention through the supplied straps, plates and bolts rather than four identical external circlips.

Applications
The 5-675X universal joint is intended for commercial vehicles and equipment using compatible 1710 Series half-round driveshaft yokes. This family is commonly sourced for North American medium- and heavy-duty trucks, buses, construction machinery, agricultural equipment and other off-highway drivelines.
Fitment and Installation Check
Before installing a 5-675X universal joint, measure the bearing cups, both lock-up dimensions and the center-to-center spacing of the bearing-plate holes. Confirm that one axis uses bearing plates and the other uses round caps with straps. Compare both grease-fitting positions with the yoke clearance and inspect the original hardware for thread and length.
Clean the yoke and cap seats before assembly. Press the cups evenly without forcing the needle rollers, install the correct retaining hardware and tighten fasteners to the driveshaft manufacturer’s specification. After assembly, check that the cross articulates smoothly and lubricate it with the specified grease before service.
Ordering Information
When requesting a quotation for the 5-675X universal joint, send the quantity, equipment or truck application, driveshaft series and photos of the removed joint. Include cup diameter, lock-up span and bolt-hole spacing when the original number is unclear. MR Driveline can review drawings or samples for production confirmation and provide neutral or customized packing for wholesale orders.
Frequently Asked Questions
Is the 5-675X universal joint the same as every 49.2×154.8 mm cross?
No. A dimensional match alone is insufficient. The half-round bearing-plate layout, bolt spacing, seals, lubrication points and supplied hardware must also agree with the original driveshaft assembly.
Does the kit include the hardware shown?
The photographed kit shows two retaining straps, two locking or bearing plates, two groups of four bolts and grease fittings. Confirm the final packing list on the quotation or purchase order.
