Design and Construction
The 5-12265X cross and bearing kit is precision-machined from high-strength alloy steel, heat-treated to withstand torsional shock loads typical of performance and work-truck environments. The bearing cups feature tight dimensional tolerances to eliminate driveshaft vibration at all operating speeds. The sealed design eliminates the need for routine greasing, ideal for set-it-and-forget-it applications.
Series Compatibility
At 0.750" cap diameter, this joint pairs with 19x48-rated yokes and flanges. Notes indicate application in: steering u joint. Always torque companion flange bolts to specification and check phasing after installation.
Installation Guidelines
- Clean yoke bores thoroughly before pressing in new bearing cups
- Use a proper U-joint press tool -- never strike the cross with a hammer
- Confirm snap rings seat fully in grooves to prevent cup walk
- No greasing required -- sealed bearings are pre-packed at the factory
- Check driveshaft runout after installation: max 0.010" TIR recommended
