Rear seal replacement tips
The rear seal sits where the output shaft leaves the transmission case, and it holds lubricant at that point. Leaks here usually show as oil on the transfer case side or around the rear crossmember. Because the seal runs against a rotating shaft, a worn lip or a scored sealing surface can cause leaks even when the seal looks fine.
Replacing the seal is best done with the transmission drained or supported, and the shaft surface should be cleaned and checked for grooves. Use a seal driver that fits the seal so it seats evenly, and avoid damaging the lip during installation. Refill with the correct fluid after the job and check for leaks on a test drive.
- Inspect the output shaft for grooves
- Clean the housing bore before pressing in the seal
- Check the drain plug and fill plug seals as well
