Installation Notes and Tips

Confirm rear-position fitment before ordering and match the vehicle year, make, and model exactly. Verify the 5-bolt hub pattern, 4 flange bolt holes, 68 mm inside diameter, and 148 mm outside diameter against the original part. Because this assembly is pre-greased, it is ready for installation, but proper torque procedures and clean mounting surfaces are still important for a secure repair.

For Nissan Altima rear hub replacement, Nissan Pathfinder rear wheel bearing service, or INFINITI QX60 rear hub assembly replacement, compare the original ABS and mounting configuration before installation.
