Rear main seal

Asked by Aug 01, 2011 at 09:10 PM about the 1991 GMC Sierra 1500 K1500 4WD Extended Cab LB

Question type: Maintenance & Repair

Hey I have 91 GMC sierra k1500, i just recently found out that my rear main seal is done for. I called a couple places to see how much it would cost to get fixed, but from what I've been hearing on the prices......i would rather do it myself. So i was wondering if there is any possible way of doing this without pulling the engine or the transmission?

One or the other has to be removed This is the seal around the crankshaft end so you need to get at it one way or the other. The usual way is removing transmission and transfer case, flywheel and its right there in a unboltable housing. Good Luck
