"High-pitched howling" noise while turning?

[t2p]

I believe the problem with my VX is in the transfer case .......
.
the transfer case may be sending too much power to the front end ....... (when it should not be) ......
.
this is especially noticeable/problem when making slow speed turns - you can feel the front and rear end 'fighting' ...... hear the additional drive train whine ........ similar to when 4wd low is engaged ..........

Still the same issues here. No solution huh?

Dude you totally scared me resurrecting this thread!

I should update, though - that sound finally went away for me. My post above (#32) said that it came back even after the rear diff rebuild and new tires. Well it did, but just a couple of times, and it's been silent ever since.

Btw, my problem was not the one described by t2p in post #37 - my screech sound was definitely coming from the back end.
