My rear main seal is somehow stuck in its housing. It had a pretty substantial leak so I bought a new one to replace it. By looking at the new one It looks like there's a metal coiled ring surrounded by the rubber housing of the seal. I am thinking of taking a propane torch to the stuck seal, similar to buring a suspension bushing out of it's housing. Has anyone had this problem before? Is it possible to burn this out or could I somehow damage the aluminum housing? Any advice helps.
