Full Description
Rebuilding a Series 2R driveshaft? The 5-2011XU from UDS brings OEM-level precision to aftermarket drivetrain service. With 1.000" bearing caps and a greaseable cross kit, this universal joint resists the stress of high-angle misalignment while maintaining smooth power transfer across the full operating rpm range. 5-2011XU is the correct-fit choice for yokes and shaft ends specifying Series 2R geometry.

Dimensional Compatibility
The 5-2011XU is dimensionally compatible with all standard Series 2R yokes featuring 1.000"-diameter bore and the ISR snap-ring groove pattern. Confirm that both the transmission-side and axle-side yokes specify Series 2R to ensure correct bearing cup engagement depth and adequate retaining ring seating.
Grease Specification & Inspection
The 5-2011XU includes a grease fitting (Zerk) at the center cross, allowing lubrication with standard NLGI #2 moly or lithium-complex grease. Purge old grease at each fitting until fresh grease appears at all four bearing caps. For on-highway applications, re-grease intervals of 5,000 miles or 3 months are typical; off-road and severe-duty applications warrant shorter intervals. Avoid over-pressurizing the fitting to prevent seal extrusion.
Interchange & OEM Equivalents
Install the 5-2011XU using a hydraulic press or cross-kit driver to achieve proper bearing cup seating depth. Snap rings (OSR) or internal clips (ISR) must seat fully in their grooves before the shaft is placed into service. Post-installation, rotate the driveshaft by hand to verify no binding across the full range of joint angle.
- Match series (Series 2R) on both yokes before ordering
- Replace both joints on a two-piece shaft simultaneously for balanced service life
- Inspect bearing cup snap-ring grooves for burrs that could prevent full ring seating
- Confirm phasing of double-cardan or two-joint shafts after assembly
