I just bought a 96 Explorer and there is a problem with it. The transfer case grinds and chatters like its not engaging. I need to get this home from about 45 minutes away. If I was to take the shift motor off and shift it manually to 2wd and kept the shift motor off would it stay in 2wd? And would I have to manually change it with the engine running in neutral or just change it not running at all? I'm new to this and have read alot on here but I'm still not sure. Thanks alot.
