Thank you for all the comments, all helpful, will try to sift through the best and least complicated but thorough as possible. My 54 1/2 ton as some of you know have
completed a complete aesthetic and mechanical restoration with exception of the driveline (yeah I know should have done it sooner but shoulda- woulda).

I can tolerate the limited speeds but the driveshaft vibration is tough to take until I do it. I believe I have acquired the most difficult to find part which is a
good 53 gear carrier. Have to acquire the rest in time. Wish I could do it now, the full resto budget was a killer.

Have decided to pull the entire torque tube and carrier assy out, (seems easier to adjust run-out, backlash and ring and pinion contact.

Hate to spend another $500 for the kit if bearings are in decent shape. Anyone know if shims have become available somewhere.
