    I would gladly trade your rear end problem with what I need to do to my truck. Z-train checks in here , you could try to send him a PM

    my last suggestion is to put the carrier on some blocks, find a bolt to put in where the broken part of the pinion shaft is broken, make it a short bolt and hit it hard, if you have drilled through the roll pin that is giving you so much heartache maybe it will break the pin and you maybe can get the pinion mate shaft Call 1 800 THE NEWS, and ask for Clark Kent, if he isn't to busy maybe he could fly over and get that apart for you. Never lose your sense of humor and never give up

    I have tried to give you the info needed to do this, any H190 rear end from another truck will work, I would prefer 4.11 gears myself, has to be from a truck because axles are different on the 510' s I used one in my truck from a 510 wagon, but had to change the spider gears to use it. That pin will come out, don't give up

    on the video, he says that one end of the pin is "staked" should be able to see where the pin is close to the surface. Drill down far enough to remove the staked area and then drive out from other side Try Datsun spider gear change in to your search engine That is how I found it, It is a video from Mike Klotz, aka (Bluehands)

    Type rear spider gear change in your search engine on you tube there is a video by Mike Klotz covering this close to the end of the video he shows what he did to remove the roll pin, try it, wont hurt

    welding your differential should be your last resort, fine for racing but for normal daily use I would not advise it If the punch you are using is a smaller diameter than the roll pin and going inside the roll pin you will just be expanding it and you could be pounding on it forever with no luck

    They can be a bear to get out, get some penetrating oil, I like Kroil, get a good quality punch or 2, the same size as the roll pin. Did part of the pinion mate shaft come out when you removed the ring gear? When you get the roll p[in out finally you won't believe the small thing that is kicking your ass, don't let it win!!!!!!!!!!!!

    Did you get it apart? I don't know where to get new parts, maybe someone has an old differential lying around that could have a good pin the roll pin should be available at any parts store. Try an ad in the classifieds, maybe you will get lucky

    Remove the bearing caps and then give it a whack with a hammer and block of wood. it should come out. remove the ring gear and the pin should slide out. you will be able to see if the pin is broken or just the roll pin broke off. those small roll pins can be very difficult o remove sometimes, Your video looks like the pin is broken, still need to get the roll pin out to remove both parts of the pin. That is probably all you need to fix the rear end
