Installation Notes and Tips
Verify shaft, housing bore, and width dimensions before installation. Inspect the sealing surface for scoring, corrosion, or debris, and clean the bore thoroughly so the seal seats evenly. Use proper installation tools to avoid distorting the lip or damaging the nitrile sealing edge. Confirm the replacement matches the vehicle’s original seal dimensions and application requirements before assembly.
