Common Uses

  • Replacing a worn front inner wheel seal
  • Addressing grease or oil leakage at the hub area
  • Restoring proper sealing around the shaft and housing bore
  • Repairing noise or contamination caused by seal wear
  • Supporting axle and hub maintenance on Chevrolet Chevette, Pontiac Acadian, Pontiac Fiero, and Pontiac T1000 models

Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation to confirm the correct match. Clean the bore and sealing surfaces thoroughly, and inspect the shaft for grooves or wear that could affect sealing performance. Use proper seal installation tools to avoid distortion and ensure the seal seats evenly in the housing.
