Thanks for the RPO codes, my truck has salvaged t case, front and rear diffs. I tried the chalk trick on the drive shaft and really didnt know what to look for. Thanks for the codes.

: You need to look in your glove box, or roll the rear tire and watch the drive shaft, I think its when the drive shaft make a complete turn, your cross that with how many times the tire turned or reverse, can't remember. Here is a site to check your glove box codes

: I would bet they are 3:73. If you 4x4 a lot and dont drive the highway a lot, then the 4:10 would serve you better, although if it is reverse, then the 3:73 will serve you better. Also, if you are running 33" tires or higher, the 4:10 will serve you better too.

: : How can you tell the difference between 4:10 gear pack vs the 3.73 gears? I think my ring and pinion need to be replaced and want to order the same gear set that I have now. 87 4X4 350.
