12 Bolt Rear End Noise Diagnosis and Repair

Опубликовано 11 сентября 2020, 14:43

This 1972 Chevy Nova with LS power has a really bad noise coming from its 12 bolt rear end. In this episode I take you through the process of diagnosing and repairing this noise. I also cover backlash, pinion bearing preload, bearing installation, setting pinion depth, reading gear tooth patterns, installing new gears, and other tips and tricks to make sure that the differential in your vehicle stays quiet and strong.

I hope you find this information useful!
