it is likely a early 1952- 1956 era 9.3 rear. You have to pull an axle shaft.
if the axle shaft is 10 spline it is Pontiac 16 spline Oldsmobile
or vise versa...Have to check that out more. Hang on will try and get some research on it. Jim

Re: 8.2. Buick Carrier Gear Pattern
looks good to me . Button it up. Or you can keep putting some gear oil on till you get a absolute pattern with out the frosting effect . I always put my marking compound in a little plastic little mixing dish and some gear oil mixed... thins it out and also makes it go further. As is it looks pretty...

Re: 8.2. Buick Carrier Gear Pattern
It is sometimes a trial and error. if you have .007 adding .002 to the pass side and removing .001 -.002 should do it. BUT that depends on how much preload you have on the carrier to depend how far it will actually register on the dial indicator. (hope that makes sense.) MATH IS EASY IN A PERFECT WO...

Re: 8.2. Buick Carrier Gear Pattern
If these were GOOD running original used gears - and all you did was a re bearing of the rear...USE the original shim and the back lash is going to be wider than .007... more like ..009...DOES not seem like this is a huge difference...but you would be surprised what it can do. Making sure your carri...

Re: 8.2. Buick Carrier Gear Pattern
Sorry for the delay Holiday stuff. You need to squirt some gear fluid onto that pattern to make the pattern come through better. NOT a ton at one time... To me it appears what you have looks pretty close. The oil will make the yellow compound move off the tooth where it meshes revieling the way it h...

Re: GM ring & pinion gear set
nothing I can see on that gear has any issues. Yes you can do a scotch brite pad wire wheel etc to remove that surface stuff.

Re: 8.2 Buick Rear end Axle Bearings
Ok, So you have a 1970 rear. It takes the A9 / set9 axle bearings. The crush sleeve is a small top and bottom. I think we can retro fit a sleeve for that. The 1968 - 1970 is ALL buick alone. It has a larger 1.875 shaft diameter pinion and it has two different size carrier bearings also. WHat bearing...
