rear diff switch-out

I'm planning to switch out the third-member portion of my rear diff this weekend. Can someone let me know if I'm missing anything? My basic plan of attack is the following...

1. Drain Oil, remove rear wheels and remove rear driveshaft
2. unbolt and remove axle shafts (I'm assuming they unbolt and slide out with no special tools)
3. remove old third-member (again, assuming once the bolts are removed and axles are out the member basically drops free.
4. replace new third-member by bolting it back on.
5. replace axle shafts
6. refill with oil

Is there a gasket repalcement involved that I've not considered?

Thanks,
Clay

Also need to remove the caliper bolts and the brake rotors. My brother and two friends did this entire job in about an hour and a half lying in the mud in the deluge @ MAR this year. None of them had ever tackled the job before.

You do not need to remove the brake calipers. After unbolting the drive members, just slide the axles out 6 inches to clear the diff. 3rd is mounted on studs not bolts, you will need to shimmy it forward off the studs and be ready to take the weight. You can use a new gasket or just rtv when installing the new one.

got it. Bill at GBR says he uses permatex ultra black. If I can locate a gasket by the weekend I'll just do the goo.

Just use the RTV, the factory does. They haven't put in diff gaskets, or drive flange gaskets for a few years now. Its all goop, and it works better than the gaskets in these applications.

Just remember that the Diff is a 58lb lump so don't have your hand pinched when the old one comes free. I have spoke to many customers with sore hands after thier diff fell out on thier hand as they were fighting with it.
Good luck
Eric

I was told by Bill @ GBR to use the paper seals at the hubs so that the play in the hub would be minimized. This was stated in reation to minimizing spline wear in the long term. Plus if you jsut spear them with grease you can often reuse them in a pinch.

If that new lump is a locker you won't want/have the stock axles for long.
