So I attempted something I’ve never done before last week, changing the differential gear oil in a GM Corporate 10-bolt live rear axle. Not as fun as I thought it was going to be. I assumed there might be a low drain plug to allow the draining of the gear oil, but no, you have to take off the differential cover to drain the gear oil.

It was fun getting my hands dirty though, seeing as how I’m behind a computer most of the time.
