    Allright, I know on atv's, you can go online and find every single nut and bolt on a diagram. Then buy what part you want .Well for a truck i wonder if this is possible. What i am looking for is a break down of the inside of the front diff, on my 2003 Z71.It is so easy to look at someting on paper that already broken down , then when you get it apart, you can compare what you have to the paper. Then buy what ya need. Does anyone know where i can find this??

    Re: front diff diagram

    This diagram is very helpful, but how would you go about ordering part of the differntial? According to the diagram I am in need of #51 which looks to me to be the passenger side of the differential or at least I think. When I put my lift on and cut the ear off of the diff I mistakenly shaved downed the wrong set of fins that help dissapate the heat from the diff. I am getting ready to re-gear from 3.73's to 4.88's and would like to fix this before doing so or should I say while I am having it done.

    Re: front diff diagram

    51 is the driver side half of the Case. If you need that then call the dealer. I don't have any part numbers just the sketch and parts list.

    Re: front diff diagram

    Does anyone know which way the front axle drive sleeve (#8 in the picture above) goes. It is beveled on one end. That end seems to fit better against the axle tube #4. When I took out the tube, everything came flying out, so not sure which way it goes. I did put it back together with the beveled end towards the axle tube and everything seems to work fine. Just wondering if I got it right. Thanks for the help.
