Brian,
Hi, I'm the one with the GPWhite Cab (We've met locally).
I'm starting to have the ring & pinion bearing noise, too.
I've driven my car with another east side shop, which said the repair could wait based on the noise level,
but it's starting to bother me especially after reading this thread again and seeing that expensive "wall picture".
So you were happy with the Monty/AA combination to have your trans. repaired, right?
I've been to Redmond European with my other car, so I'll go this route unless you have other suggestions.
I'll have GT-LSD installed at the same time.
With the other shop, I was given a rough estimate of much more than it cost you, fyi.
Any suggestions are welcome.
