This video chronicles what I went through to diagnose a whining noise coming from the 10 bolt (8.5” 30 spline) differential of my 1990 C1500 truck (GMT400/OBS). The noise has been there ever since I installed a new carrier and gears last year.

I cover checking backlash, measuring pinion depth, bearing inspection, gear tooth patterns, and fluid inspection.

I hope you find this information useful!
