I want to replace the gasket between the front and rear differential housing. I am at the point where I have the 8 screws removed and gasket broke loose but the 2 halves do not seem to want to come apart and I do not want to damage anything. I did not remove the axles and did not separate the transmission as I didn't see a need to do that. Do those items need to be removed? Anyone have experience in this area? Help is appreciated.
