Im getting tierd of the high speed vibration. Was going to wait for the eaton install but have to wait on that. Who did you order your shims from and how much? I would like to start with the 1* and move from their. Still dont know if thats the problem, Thanks.

 

You're talking about pinior angles? Start with a 2* shim. It'll be easier to find. Symptoms of pinion agle issues usually show during high torque events like taking off or under heavy throttle, not while just cruising at any given speed.

 

I just want to try it, it happeneds at about 70 mph and up.Maybe inside the rear end. Just feel its cheap to try it. Or take drive shaft back to balance again.
