I am getting vibration from 25 mph to 55 mph in the drive train. When shifting to a lower gear going down a steep road I get a clunk. Sounds like U joints but they don't look loose. When I turn the drive shaft that is in front of the transfer case I hear a noise in the transfer case. Can U joints be bad but still appear tight? Can a transfer case be rebuilt like other components?
