    Hey guys discovered on friday that my rear diff is leaking. Looks to be a slow leak, I'm thinkin it's the seal, for at the time I had bigger problems to take care of and didn't get a close look at it. Then didn't get back till late last night. Dave or Alan or anyone else replaced this seal before? Is it easy to do? Do I need any special tools? Where should I get the seal from? I know this should be in the tech section but I like askin you guys first. Thanks for the help

    Chuck

    If it's the rear diff cover, just clean off the old gasket material and use black RTV. If it's the pinion seal, you need to remove the flange and pop out the old seal with a screw driver or other implement of destruction. Lastly, make sure the fill/drain plugs are not leaking.

    I hope your not talking about the seal where the driveshaft connects Chuck. Because my spare one leaks there and I asked about replacing it and basically got told what a pain it was and how hard it was. So then I welded the other one and put it in instead. Of course this one is leaking from the drain plug so I have to take a look at that at some point.

    No Ibelieve it is leaking around the large mounting plate. Do I need another seal or Just the Black RTV? Also where can I get a pinion seal, probably just go thru Rick, cause I've look on line and can't seem to just find a pinion seal.

    you don't want a pinion seal if it is just the diff. cover that is leaking, I use the black silicon too and it worked fine for me.

    Chuck I think I have them both. There is a rubber one and a cork one. I cannot remember which is which. If you need it let me know. I replaced mine because the PO didn't believe in seals and when I did the locker I put a new one on. I'm pretty sure I bought extra though. I'm going to use one when I do the Cut and turn next weekend. Yes I'm going to do it myself. It doesn't look to hard. And I'll save some money doing it myself as well as time.

    I prefer cork

    Black RTV stuff works great. Just don't get carried away.
    A small constant bead around surface at contact area.
    I prefer OEM cork. Very clean install. Good time to remove the fill / drain
    plugs and use new gaskets there too. I think the plugs are 22mm.(duh...it's 24mm)
    A six point socket helps on the stuck plugs.

    Just doin some rereading over my post, Dave you mentioned new gaskets for the drain and fill plug. Is that an actual gasket or new washer with that RTV stuff? Can I buy and make my own gasket or should I order a gasket specifically made for that. Sorry for all the questions, I just wanna do this job once and have the leak stopped.

    Thanks Chuck

    what's in a name?

    Uh.....the drain/fill plugs use washers not gaskets.
    I've just found that they get pretty deformed over the years
    but if they aren't leaking.....forget about it!
