    What need to be replaced to do this? My impression that diff + diff housing is enough. But one wrecker told me that whole axle need to be replaced because it is different inside. Is it true? Also is all diff from 80 series interchangeable? I mean all cars have the same final ratio (i.e. diesel / turbo diesel / petrol; auto / manual trany; different modifications GLX / Sahara etc.)?

    Thanks

    Boston Mangler recently completed an excellent write-up on this. Should be in the 80's FAQ by now, I'd think.

    Edit: I just checked, and it is not in the 80's FAQ. Mods, *please* add Boston Mangler's writeup. He spent a lot of time on it, it is very thorough, and it should definitely replace the comparatively useless retrofitting thread that's already in the FAQ.

    You need a diff, RH axle shaft, some studs, Wiring (either home brewed or factory), difflock ECU, difflock switch, dash indicator bulbs and sockets.

    Is there a way to print Mangler's writeup so it fits on 8 1/2" x 11" paper? I've printed it, by the right side is cut off.

    Thanks,
    Rookie2

    Try copy and pasting it into MS Word, that has helped me print stuff like that in the past. There is also a "Print To Fit" option somewhere in the print menu!

    Rookie2,
    If you haven't tried the Firefox browser you should. It will print OK using FF. If this isn't an option for you then PM me and I'll create you a PDF and e-mail it to you.

    BM,
    The mods work hard to keep the forum running smoothly and posts in the appropriate place. If you'll treat them with the respect they've earned I am sure your life here will be a lot easier.

    If you'll recall, you and I had an off-line discussion after you came crashing in here acting like a juvenile. We quickly mended fences and I have no problems with you but you shouldn't publicly lash out at the moderators and expect nobody to say anything.

    I suspect KSV may be down under based on the references for 80s he gave. Dan, you got the international shipping set up?
    :D

    If you are only swapping in a pumkin and bit, you will also have to cut and grind on the housing and weld in some extra meat in another and drill and tap some holes. The easiest way is to take the whole axle houseing with the diff and just swap it out. Saves alot of work and buying the stuff at higher rates fi bought in single parts. later robbie

    Thanks :)

    Thanks - does not work, cos I am in Oz :)

    I have not decided yet what to do - fit factory ones or 3-rd party. I like to have factory lockers, but prices from wreck just ridiculous - he wand sell me whole lot for price almost twice higher than fully fitted 3-rd party!

    Thanks again

    If he is only doing the rear, no "Meat" will have to be added and no holes will have to be drilled.

    That is only for the front!

    I STRONGLY disagree here!!

    NOTE: I am speaking about the REAR diff (which he asked about) not the front! The front is a different story!

    front is the hardest part if you don't have the whole axle assembly for elocker. I did drill, tap for the 4 new studs location, and grind notch to fit the the 3rd into the stock housing. The rear went pretty easy since it was a complete swapped.

    Anyone know if the 95-97 had the harness (pl?) that Boston Mangler references that his 93 has?
