1982 chevy 4x4 axle ratio

[ElGracho]

Axle code GQ1 - Standard ratio depends on the powerteam (combination of engine and transmission), drivetrain (4x4 or 2wd) and the GVW. You can't just say 4x4 standard ratio is x.xx, you have to take into account the engine and GVW. Some heavier half tons had different standard ratios than the lighter ones.

Like 1969k10stepside said, the best way is to open up the diff and look at the numbers stamped on the ring gear. It won't have the ratio spelled out, but it will have numbers of teeth on the ring gear and pinion, you just have to divide.

Remember, these trucks are 20 years old at the youngest. Almost all have over 100k miles and could have easily worn out there original axles and had others swapped in somewhere along the line.
