Our Front Differential Rebuild is a must needed upgrade over the stock components. However, there’s a few front differentials that need a little extra TLC with 4WD.

Send your front diff to us and our certified tech will troubleshoot and correct the noise. This price includes installing our upgraded bearing kit, custom shims to set the lash on the ring and pinion gears and also bench load test your diff before we ship it back.

***You are responsible for shipping the diff to us!***
***We use assembly lubrication when building and bench testing your diff. Please make sure to fill your diff with oil once you receive it.***
