:banghead I have a 95 Bronco with a 4" stage two lift (extended radius arms). The problem I'm having is when I shift to 4 wheel drive I get a terrible vibration. The vibration also occurs when the hubs are locked and not in 4 wheel drive. I thought it might be the transfere case, but I was wrong. I just had it overhauled last week and the vibration is stil there. I have new front wheel bearings & new front drive shaft U joints. Due you think it could be the drive shaft angle? Could it be axle shaft u joints, there the original ones 130,000 miles. What are exceptable dive shft angles? Any and all help or suggestions would be great.
