Installation Notes and Tips

Verify seal dimensions and vehicle application before installation. Inspect the pinion yoke, shaft surface, and surrounding housing for wear, scoring, or contamination that could affect sealing performance. Clean the sealing surface thoroughly and confirm the replacement seal is seated squarely during installation. For best results, match the part to the exact year, make, model, position, and notes listed for your vehicle.
