Installation Notes and Tips

Confirm bearing cap diameter, snap ring style, and rear shaft application before installation. This part is specified for rear shaft all joints and uses an outside snap ring style, so matching the original driveline configuration is important. Clean the yoke bores thoroughly, verify snap ring seating, and grease the joint after installation if required by service procedure.
