Q: I have a very slow leak coming from the transfer case.

asked by on

What is the most common cause for a low mileage car to get a leak in the transfer case? Is there a simple and inexpensive fix?

My car has 104000 miles.
My car has an automatic transmission.

The most common leak from the transfer case is the rear output shaft seal. Of course, the condition of the bushing and/or bearing at that location will have to be verified because excessive play will make it impossible for the spring loaded seal to do its job. If just the seal has failed, and everything else is mechanically in order, replacement of the seal takes 2-3 hours. The seal itself is nominal in cost, probably in the range of $10 to $25 for the part depending on OEM (Toyota) versus aftermarket.
