Installation Notes and Tips

Verify bearing cap diameter, cap-to-cap length, and snap ring style before installation. This joint uses internal snap rings and ISR-style bearing caps, so the driveshaft yoke must match those specifications. Clean the yoke bores thoroughly, pack the joint with grease before service, and confirm smooth articulation after assembly. Always compare the removed part to the 5-3229X before pressing in the new joint.
