[T3] Noisy Tranny

[Keith Park]

It’s a freeway flyer, I think they changed 3rd and 4th, I know 4th is
lower... id have to check the spec's again.
Question is what bearing, and what caused it... they shipped it back to me
in a cardboard box so the input shaft could have taken
A hit and damaged the bearing or it was shot to begin with.  Now the
question, how long will it last?

SO much work to fix this now....

Rebuilding VW trannies is really hard. I suspect that most of the rebuilders
out there don't bother with all the checking and reshimming that a careful
job requires. Bearing dimensions are extremely precise, so you can skip the
shimming if you're only replacing bearings, but I would not be surprised if
the rebuilders end up mixing and matching ring & pinions to use as many old
parts as possible.

If you asked for a change in final drive ratio, I'm willing to bet that you
got a different (used) R/P set with the shims it came with, but no new
shimming to fit your case. That's not a good choice.
