My brother just purchased an 89 4X4 and we were just wondering what the front and rear axle ratio might be. Where exactly should I look as I could not find a code on the door jam? Some codes and a place to find the codes would be greatly appreciated. I am sure this has been asked before but would appreciate again any help. Thanks

If you look inside the glove box there should be a white sticker with a bunch of 3 letter code's. These are know as your RPO codes (basicly they tell you what options your truck came with)
There are a few places on the net where you can enter these and find out what you got. i'll see what I can dig up for ya.


*edit*
here ya go try this ..enter them one at a time all may not come up but many will
