Can anyone recommend a shop that can rebuild my 8.8" rear? It's several years old now and I figure its due (I know for sure the pinion bearing and seal has 220,000 miles on it.)
Now that I think about it, I can do everything EXCEPT set the pinion gear. Can anyone do that or does anyone know of a reliable shop that can install it to the correct Ford depth (it's a Ford gear set.)

Standard Transmission and Gear in Fort Worth can certainly do it but you should be able to find someone closer.
Call Richard Painter. He can set it up for you.
Dallas Mustang may or may not want to touch it
I could do it, but have zero time for my own crap right now...
Same here, but I've never set up a pinion gear, and I don't have the correct tools to do it. Perhaps we could work something out for just the pinion?Quote:

Really? How do you set the pinion depth correctly?Quote:

The crappy part about setting the depth is that it is properly measured to the centerline of the main caps, so if you can devise a method/tool to accurately locate the centerline of the main bearings/caps/axles, you just add shims under the pinion until you get the distance from the top of the pinion to that centerline correct. The pinion is the easy part. The backlash is the hard part.
When I installed 3.73s I just miked the old pinion + shims, then measured the new pinion and added whatever thickness of shims I needed to match the total length of the old one. That will result in the same depth. Just don't do what I did and think that the inner bearing race is seated just because it's flush with the case...
To me the backlash is the easy part. Just move shims from one side to the other until your pattern looks right. The best thing to do once you find the right amount of shims is to buy a single shim per side that's the total thickness you end up with, rather than multiple shims that can shift around.

Has anyone ever used this?

It's a gauge that sits ON the pinion shaft and provides a measuring surface between the bottom of the bearing pocket and the gauge itself. There are models specific to the rear end being set up (#10006 is the one for the Ford 8.8.) At $30 at Summit, it's cheap enough for me to grab and do the rear end myself. If I install the pinion and can't get a good contact pattern, I can always have a shop re-do it.
David Painter (Richard's Brother) has a shop in S. Ft. Worth, he did my tranny and rear end. (817) 447-1900
I'll use him every time in the future again. Too many guys do it themselves, don't save enough to even justify the trouble, and complain about failures. I just can't go that route.
