Re: I think my C10 rear axle has a 2.5? rear gear ratio / is this true
Took the cover off just a bit ago. Found a part number on the edge of the ring gear. The number is as follows:
W GM 1235401 16 41 10 83
Also, I counted the teeth on the ring gear and pinion gear:
Ring gear had 41 teeth
Pinion gear had 16 teeth.
Found a part number on my axle tube: BN3 G300 1
And two part numbers on my center chunk, one on the left and right of the center: what looks like GM36 on one side and looks like maybe 14055251 or 405525 on the other side. Not sure what those mean.
