Re: IML: Sure Grip Whine/Shops

[PAUL WENTINK <randalpark@xxxxxxx>]

I only deal with shops that I trust and will leave my precious car/cars 
with. That is so that I know that it will be done right when I get it 
back. There are folks who can rebuild and set up the differential 
outside of the car, but that is a skill most shops don't have.

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.

No, I removed the 3rd member myself and handed it to them. I then 
reinstalled it. I NEVER like leaving my precious car with mechanics 
unless absolutely necessary.

If they rebuilt it, they may have adjusted something incorrectly, but a 
good shop would not have released the car until the the work was right. 
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.

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. 
 
 
Thx, 
 
Chris

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.
