### ⭐⭐⭐⭐⭐ Quality is top shelf, just to the right of the dapper dan
*by A***W on December 16, 2025*

Just what I needed for my ‘05 Tahoe z71.

### ⭐⭐⭐⭐⭐ GM 12 bolt truck differential rebuild kit
*by B***8 on January 27, 2026*

Everything was just as described, good quality bearings, very pleased with parts! Recommending the seller items!

### ⭐⭐⭐⭐⭐ Have the proper tooling before you buy.
*by K***R on June 29, 2014*

Everything was of good quality. Koyo bearings I have read are reliable. Plenty of shims for adjusting backlash and bearing preload. And there is a booklet with detailed explanations on tools and technique included underneath everything. Too bad I found it after the fact. I highly recommend buying the proper tooling before attempting a rebuild. It is quite an investment, but you will need a clamshell bearing puller, dial indicator and stand, torque wrench in ft-lb, a dial indicator torque wrench in in-lb for pinion bearing preload, and though possible without but still recommended, a case spreader for removing the carrier from the housing and a bearing warmer to easily install the bearings. Well over a $1000 for all that from reliable brands. Also when setting up your shims, hone out your old bearings (or you can buy setup bearings) and have your old inner pinion race taken to a machine shop to take a few thousandths off the outside (or buy a setup pinion) so that you easily install and remove to add or subtract shims when setting your backlash and preload. It is very time consuming and a lot of patience is required. If you don't have the experience you will install the carrier four or five times to get the shims right, but it is not too difficult if you take the time to do it correctly. This was my first axle rebuild but I plan on doing more in the future, so it was worth the time and investment to do it myself.
