If you can find markings (usually on the passenger side axle tube on GMs), you can usually find something online to decode them. It's usually a 2-character code. Here's a page with examples from old Nova rear ends: https://www.novaresource.org/axle.htm. If you can't find that, you can always pull the cover and count gear teeth.

The codes on the front axle may not necessarily translate the same as the rears but I'm in no way a 4x4 guy so I really don't know on that. I'm assuming the front axle is still factory? You can probably find some info online about what kind of axles you could get in those trucks. I would think it would still be stamped with a code somewhere though.

22 Eargesplitten posted:Does anyone know where to find the gear ratios of the various transmissions and years? I've got a '92 with a 5 speed manual and no tachometer. I've never driven a V8 before so I don't know what different RPM sound like. I'm going to be towing soon so I expect I'll want to be in 4th for that but I want to calculate RPMs to make sure that I don't sit near redline. I swear for a generation that talks about "hur hur kids today can't drive stick" everyone that owns one of these chose the automatic. Your truck probably has the HM290. If that's the case, here's a nice paper with some good info on it: http://tcase.rsgear.com/articles/1993_03.pdf
