If you’re
asking me, Chris, I’d say get it to a shop and have them set the pinion
engagement per the detailed instructions in the shop manual, using a new crushable
sleeve, and check that pinion bearing. There may be nothing else wrong, just
an incorrect adjustment.

Subject: Re: IML: sure grip whine
I got two high recommendations from from car people in
the area. This shop is a rear end shop exclusively. Here's their
link: http://www.rearendshop.com/index.html
The owner sounds like he knows what he's talking about but now I'm a little
suspicious.
Sounds like I should replace the ring and pinion too since
this has been an ongoing problem?

This is the
first mention I’ve heard that the whine is on power only. That is
often the sign of a bad pinion bearing or incorrectly set pinion to ring gear
tooth engagement. The shop that rebuilt your diff should have checked
that thoroughly, and reset the pinion engagement to specifications. If they
missed this, or aren’t aware of the need for it, find a better
shop! Consult your shop manual for specific instructions on this, or if
you don’t have one, copy the appropriate pages from the one on the IML
site.

The whine is power on only. It's always whined while
I've had it. The only thing left to whine is the R @ P. But I guess
it's a shot in the dark with a used one because the shop might think it looks
good but it might whine anyway.
Can someone tell me if the shop should have known by looking
at the R @ P that it would whine? My original complaint was the whine.

I don't think you ever stated, if the noise or whine is with power on,
power off, or coast. If it made the same sound before service, it was probably
repaired before and not set - up right. In that case the ring and pinion
would wear incorrectly, and make noise. If the service done now, simply
re-shimed to the old set-up, or possibly correct, the noise will continue. Any
adverse whine or noise is tell-tale premature ware. If a used ring&pinion
are installed, very careful set-up should be done, or the same problem will
exist, since the gears already have a ware pattern set. The standard
2.76-2.94-3.23 should be whisper quiet. Dave.
