Installation Notes and Tips

Inspect the output shaft, seal bore, and surrounding surfaces before installation. Clean the sealing area thoroughly and verify the seal dimensions against the application before pressing it into place. If the shaft surface is scored or worn, replace or repair the affected component so the new seal can seat and seal correctly. Confirm rear-position fitment for the specific vehicle and build date, especially on the 2004 BMW X5 application noted from 10/01/03.
