Re: front end disassembly.The bump rubber bolt on the lower wishbone must be rusted to the wishbone....many soakings with liquid wrench and hammering does nothing...I'm reluctant to try heat. The manual says to install a 3/8"x6" bolt in place of the bump stop and one on the other side to act as guides when lowering the pan. Others have not mentioned this when doing their diassembly. Is it stricly necessary or can I successfully lower the pan without the guides so I dont have to remove the [censored] bumpstop? Karl
