Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation to confirm the seal matches the axle assembly. Inspect the shaft surface and seal bore for scoring, corrosion, or debris that could affect sealing performance. Clean the housing thoroughly and seat the seal evenly to avoid distortion. Confirm vehicle application details, including the Spicer 205 transfer case note, before ordering or installing.
