Rear tray for my rusty '86 pickup

[mongoose2231]

No need to read it all. It has new ome springs and bushings in the back. The noise did not appear immediately after the lift in the back. It kind of gradually came to be. Perhaps after the lift in the front It got worse. But not sure how they correlate. I'd have to get shims to change the pinion angle. Do t want to be cutting and welding anything yet.ill remove rear shaft and drive without to see.

Removed driveshaft, drove in fwd and it no longer makes any vibration. I need to speak to Tom Woods to see if I can get one of their custom dc shafts. Pfft, I wonder why the vibration didn't show itself right after the new lift and it only showed now, two years later.

Wear and tear?

Spoke to Tom Woods, they said to try balancing the shaft before I buy a dc shaft.
Imma try doing that first.
