this will help you to figure out your ratio using the A/TR code found on the ID plate on the inside of the driver's door jam.

It's not part of the VIN. With that VIN you could have one of many different gear ratios. You need to find the axle code.

It needs to be from a vehicle with the same axle code(and ABS if that's what you have). Or from another 4WD truck or 4Runner with the same gear ratio(and ABS if that's what you have). 2 or 4 wheel ABS has nothing to do with it, because it's a rear axle(since if you have 2 or 4 wheel ABS, the rear axle has ABS either way, that's why it's not even called 2 wheel ABS, it's called rear wheel ABS, or 4 wheel ABS if the front has ABS too).

Your talking about the cvs. No gear ratio involved.
