I've got an 87 Cherokee with the 4.0l. I have removed the pan, removed the rear-most bearing containing the bottom portion of the 2 piece rear main seal and I can't get the top portion of the seal to budge... Tried a punch, a little bit longer screw driver, but to no avail... I feel like something longer in there would allow me to get a better swing on it since I'm in such a tight spot, but kinda afraid to hit it too hard.. don't want to scar any metal parts. Anybody got any ideas?? Thanks

 

It takes a pretty good whack with a punch and hammer but once it moves it will slide right out.

 

It is a real pain, best bet is to find a small metal rod as close to size as possible to the seal and give it a good wack, i had the top part of mine get stuck too. What was said before me is what you want to do

 

push on it and turn crankshaft with harmonic balancer nut will spin right out install same way use plenty of oil on seal when installing
