Back in 1985, I found a "differential man" in my area. He came highly recommended, and by folks that I knew were honest. He rebuilt a Sure Grip for my '65 Imperial, and explained that if it made any sound or was "too tight" after I installed it, he would like to have the car in his garage for a day to fine tune things. He was good enough at what he did that it was right the first time, as I hoped and he knew it would be. Ever since, I have allowed a reputable shop to do the work start to finish. I am past the days of changing that part of the car myself. I drive cars a lot of miles, and I have had to have the differential rebuilt in two more Imperials, a 1981 Buick, a 1976 Ford Pinto, and a 1980 Lincoln. Each of them turned out perfect.
The shop that suggested a junk yard isn't all that wrong. If there is a way to test the part before hand, or at least thoroughly inspect it and what it came out of, there is a good chance it will be silent when you install it, since it probably wasn't the reason the car was junked. There are times when I prefer a good used part to a newly "rebuilt" one, and a third member is one I would consider under the right set of circumstances and out of the right car.

I then reinstalled it. I NEVER like leaving my precious car with mechanics unless absolutely necessary.

Did the owner of the shop test drive the car before you paid for it and picked it up? There should be no sound from the differential.

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.

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. -------------- Original message -------------- From: PAUL WENTINK <randalpark@xxxxxxx>
It isn't suppose to make any noise. Paul W. -----Original Message----- From: Chris Strohmeyer To: mailing-list@xxxxxxxxxxxxxxxx Sent: Sun, 17 Feb 2008 8:58 pm Subject: IML: sure grip whine Hi again all!  Well, I just had my sure grip rebuilt because of a whine by a
reputable
rear end shop here. I took it out myself and handed it to them. Replaced all bearings and clutches, but not the ring and pinion
because
it looked good to them. $540. worth all together. They showed me the clutches and they were in terrible shape-broken and such so it needed doing.  Guess what, the whine is still there! The rebuilder drove in my car
and
said it's the ring and pinion. He was wondering if this might be the nature of this beast? They said they'd be willing to drop in a used ring for $150. more with no guarantees on the whine because it's
used.
I really don't want to sink more $ into this if I can help it for a
new
one  What are your opinions about this possibly being normal and is there any magic oil that might quiet it down a bit?(besides bananas?) Anyone?  Thx, Chris Strohmeyer 67 Imperial Convertible/haze green/black top/green interior  ----------------- http://www.imperialclub.com ----------------- This message was sent to you by the Imperial Mailing List.
