Sorry. The rear axle bound up so I stopes to check it when I got back it and pit it in gear it wouldn't move so I put it in four wheel and it still wouldn't I gave it some more gas and I could feel something let loose which was the rear drive shaft. My guess is I blew the rear and when it locked it caused my drive shaft to twist and break. Planning on pulling the rear cover off the diff to check out inside for damage. The rear shaft is in two pieces. So I know I'll need a new one.

driveshaft i cant help you with,

rear it all depends on whats broken, take her apart and find out what she needs. its strange that it would lock up like that...

I destroyed the stock rear in my duramax however that won't cause it to seize just not not move. I've also broken an axle shaft and that also won't cause the things he's speaking of.

He could of broke the pinion causing it to seize but then the driveshaft would spin free...it must have somethin to do with the ring and pinion without the pinion shaft itself breaking..... Like if something jammed the gears

ouch, similar to mine but a little more carnage.

pull both axle shafts to inspect for damage/swisted splines. if those are ok (probably are) you should be good to go with a new differential, carrier bearing, and driveshaft.

if the trucks planning on being a street/strip warrior may i recommend a Detroit trutrac diff, works wonders in my truck

you guys think i can get away with just throwing a new g80 in it and if i do that dose i have to adjust the back lash or no since its the same gears i have the idea of what to do with backlash i have just never done it personally
