Installation Notes and Tips

Verify shaft, housing bore, and flange dimensions before installation. Clean the sealing surface and hub bore thoroughly, and inspect the axle and hub components for wear or scoring before pressing in the new seal. Confirm vehicle configuration carefully, especially on Chevrolet K1500 and GMC K1500 models with 8 stud hub setups, since fitment varies by application.
