Review on 🔧 Efficiently Adjust Bearing Preload with OTC 6602 Differential Preload Wrench by Jonathan Ulsth

I've been involved with cars all my life and I've never heard of such a tool. What I thought was an easy fix turned into a nightmare! Why? Because I didn't have a tool to preload the diff bearings. 2 days of searching and trying to do something on site were in vain. finally ordered it from Revain, received it in 2 days and it took (no kidding) 3 minutes to loosen the bearing preload! Remember I already disassembled my diff, but it's a lot easier with the right tool. Buying works great.
