To cure mine I:
– Balanced my wheels/tires & set my alignment
– Checked my suspension bushings, transmission cross-member bushings, the trans mount, and engine mounts
– replaced front & rear u-joints
– set pinion angle parallel parallel to the transmission/engine
– replaced axle bearings
– ensured my pinion flange nut wasn’t loose
- took D/S to transmissions shop. Balance was fine, but D/S was not true. They used a heating and cooling technique to true it. However, they could only get it to .008" & there is still a noticeable vibration. This is/was one of the factors that eventually drove me to swap in a T56 which will end up replacing trans, both yokes, both U-joins, and the driveshaft. *fingers are crossed*
Putting it on a lift and running the drivetrain is a technique I've used... I've even crawled under the car a bit before deciding that doing so just wasn't worth the risk of some garment getting caught up in a rotating part and getting myself mangled. Plus, when the suspension is unloaded all of the angles change and bushings are unloaded. So, while it might work, it might not reveal anything.
