We’ve decided to bring you our own version of a ‘how-to’ video.
If you’re rebuilding or re-gearing a GM/AAM 9.5″ rear axle (same as a 12 bolt and semi-float 14 bolt) this video may be of use to you.
This video format assumes the viewer already has some general knowledge of what it takes to install a set of gear in an axle.
Specs:
*Ring Gear Torque – 75 ft lbs
*Bearing Caps – 80 ft lbs
*Pinion Bearing Preload –
15 – 22 in lbs with new bearings
7 – 9 in lbs with used bearings
*Backlash – .006″ – .010″
For break-in procedures, check out this video from Yukon Gear and Axle.
Let us know if this video actually helped, or if it was the worst possible how-to video you have EVER watched.

I'm having a hard time understanding the difference between the gm 9.5 14 bolt and the gm 9.5 12 bolt axles and diff compatibility. Do you know if 9.5 gears and carriers can be swapped between the two?
Thanks for the video… now I know I don't have space or tools… FULL FLOAT SWAP HERE I COME!
Tips for setting pinion depth without having to pull and press the outer bearing a bunch of times ?
Did the 9 1/2 diff ever come limited slip? Swapping a 3/4 ton drivetrain and axles into my 1/2 ton cateye for a trail rig
excellent – I need to do one of these
So, pinion depth remained the same?
if you leave the top bolt in the diff cover you can break the seal and drain the fluid without dealing with cover…
Questions .comments. concerns….. spoken like a n.c.o..
Nice vid. Y'all should have threw in one of those 600 dollar tru tracs in while you were at it.
Hay Chris, if we don't forget to do something once in a while ,We don't get to look back and laugh at each other over a few beer's ,keep doing the good work you do.
Nice video! break in process?
The part no one ever shows is what the "happy paint trail" should look like. I know to add or remove shims to adjust, but Iv never seen anyone explain what to adjust to, what kind of trail I should be looking for in the gear paint.
Science , and dam y'all made that looks easy
Glad to see all that liberation going on!
In our country vehicles don't have a C clip inside the differential.
I never realized the 3/4 ton Burbans were leaf sprung. Did you consider putting a full float 14b in it?
I like tacos….lol…
