  • '84 Rear end

    Ok need a little help my uncle has a 1984 Z28 with the 5.0L H.O. engine. he siad the diff locked up (the tires wont spin) on him going to work the other day and all the fluid leaked out so something big happened. I have not got a chance to look at it yet but was trying to find out the diff spec's the dealer said its too old to give them the vin number for info. from my understanding there were 2 types of axles used a chevy and borg warner also 4 gear ratio's as well 3.08,3.23.3.73,3.42

    How can i find out which one he has? Thanks

      my suggestion is to join a 3rd gen website, and tell them about the car, and they could narrow everything down for you.

      are there no rpo codes that could give you a clue?

        ya looks like im just gonna have to take it apart next weekend hopefully there will be a tag still on the rear end with info on it. just thought i would try here first in case someone had input on it since the dealer was no help.
        Thanks anyways guys.

          NO tag on GM rears unless it says " Limited slip differential fluid only". If it's the Dana You'll know as soon as you look at the cover.

            I haven't looked at my haynes or 85 service manual, but if the rear is anything like the 2nd gens, there will be some numbers on the pass side of the axle iirc, that can be used to determine what type it is. also need to know what tranny he has for ratio

              I'm betting he has the 3.23 rear.
