Trying to find out where this vibration is coming from. Removed front prop and took it for a test drive. Vibration still there. Took rear prop off took it for a test drive, no vibration. Prop looks all ok UJ's, seem fine. Now I'm wandering if its the rear diff or something in the transfer box. All wheel bearings seem good. Anyone know where to get a rear diff for a 1990. 200tdi, 110? I was getting a klonk from the rear diff when I engaged power which sounded like the A joint but I know that is fine.
