Right rear axle came out of differental while travel'n 70mph
Axle is very bent and tube end that holds break shoes is now in a half moon shape. might have damaged the bottom of the shock and I know the break line hose is ruptured (had to put out the brake fluid after it caught fire)- how
I tell what damage might be in the differental itself? (haven't pull cover plate off, yet, don't really know what to look for, especially the "c clip" I keep hear'n about
when assess'n the total damage; what should I be look'n for?

Have you had a four wheel alignment done recently? Do you replace all the links in their entirety, or just the bushes? If just the bushes, try an aftermarket set of poly bushes?
what happened just before 70k? Did you have a crash? Did you damage the axle/housing (bent rear axle)?
please tell us how you solved this problem as it could help someone else in the future..thanks.
`right one of two problems ,firstly remove the rear drums and check for a fluid leak as a slight smear of fluid will cause the exact problems you describe ,if the rear shoes are dry then push the cylinder each side to make sure its not seized ,secondly check the load sensing valve which will be under the chassis above the back axle,if that appears ok and not seized then remove the master cylinder and take the piston out and check the rubbers and the cylinder bore for wear ,but mainly this fault is caused by the brake shoes having a slight amount of brake fluid contamination and it causes the brakes to grab
you have to remove the four bolts in the brake back plate ,then remove the rear cover on the diff ,then strip the planet gears ,then on the end of the half shaft is a horse shoe shape clip ,pull this out then the half shaft comes out
These are most likely part of the accident damage. While you are fixing this double check to make sure that the axle on the side that was hit isn't bent as well. Also check the axle tubes from the differential to make sure they aren't bent either. An accident that had enough force to break a spring and bend a driveshaft is strong enough to bend the other parts as well. Been there, done that, got the T-shirt. Check the axle and tubes carefully and be sure. Hope this helps.
Put rear tire's on jack stand's, remove left rear tire, brake caliper and bracket and slide off brake rotor, then remove rear end cover get a pan for fluid to drain into,there will be a set of gear's through the gear's on the right side of the ring gear there will be a pin about 13/4" in dim. and about 5" long at one of the end's there will be a small bolt that hold's that pin with an 8mm head going through it, remove that bolt,slide pin out, go over to axle push in (do not turn axle) go back under truck remove horse shoes clip at end of axle, then side axle out, install new axle and refill with gear oil some take a anti-slip additive.Goodluck
There is a vacum switch in the transfercase on the drivers side. you can get to it with a wrench, but it will make you work for it. Part store is like $45.00 GM like $90.00, Same part.
Rear bearing. remove the differental cover and drain fluid. Remove the C Clip that hold the Axle in. Slide the Axle out and inspect to see if you need a new one. High mile axle has a worn grove where the bearings are and changing the bearing alone does nothing. You ight get away with a finding a bearing to match your axle if it's worn.
Remove the oil seal and then the bearing from the axle tube.
In-stall in revers, note use lots of lube on the seal and be careful not to nick the seal and bearing.
Fill differental with oil and run around the block, not hard and re-check the fluid. May want to go with syntetic oil or add lucus. Less maintance of oil changes to differental.
Good luck and hope this help.
Rear I take it. Cover off. Push in slightly on axles & look at end of shaft inside housing. Small lip, then groove, then rest of axle to outside. Inside that groove should be a half moon "C" shaped retainer that needs to be taken out, then axles should slide right out if it's like a standard axle.One on both, just push axle in, and you should see it. Let us know.
remove the calipers and rotors. check your e-brake shoes inside the rotors. also check your axle seals, if they are leaking. make sure, that no gear lube is present. If all is dry, than check the breather valve which is installed into the r/h axle tube on top. make sure, that it is free and spinning, because that's how the rear seals in titans blow out. The breather gets stuck and rear end doesn't breathe and youe axle seals will blow out and all other seals in rear end. common problem w/breather getting stuck.anyhow, check your e-brake shoes, they may have fallen apart.
Axle bearings? If so then you used a slide hammer with the half moon shaped adapter. the half moon spins straight to go into the bearing and then turn to catch both sides and then you pop it out. pinion bearing have to have the front yolk of the rear end taken off and the rear pan to gain access.
