G80 on its way out?
I was driving spiritted but not hard by any means on my way to work this morning and my truck started making noise from the rear like wawawawawawa. The loudness and the frequency of the wawa are both proportional to the speed. It would be loud if I went fast but I can't feel it at all. Anyway, I turned around and took it real easy back to the house and got my little gas saver to drive to work. Does it dound like the locker might be f-ing up? I'll take it apart tomorrow and see if I can find the problem.

do you mean the differential or the housing? Is it time for a new eaton?
Here's a pic of the diff still in the truck.
I'm hoping to not have to change out the gears. Although, I have considered swapping out my 4.30s for some 3.73s for fuels sake. But I'd have to do the front too and none of this is in the budget. I'm going to pull the diff out this afternoon. Wifey has me doing another project this morning and it's ont like I can get a new diff today anyway.

I got it. I guess you just have to beat the axles in with a big hammer sometimes. You'd think I've never done a set of gears before.
Anyway, I got the diff out. There doesn't seem to be anythig wrong with anything. Just two bolt heads that broke off for some weird reason. Maybe I over torqued them or something. There is still a nice preload on the pinion bearings and the backlash was at .009" before I took it apart. I didn't check the gear pattern but I'm not worried about that. They were quiet.
Just because nothing was damaged doesn't mean I'm going to put that G80 back in. I never liked that thing and I know I'm going to break it. I'm pretty sure I'm going to order an Eaton LSD or maybe the Yukon version. If anyone wants to trade their 3.73s for my 4.30s, let me know now. I'll do it but I need fronts and rears.

Well, even though I'm about the only one in my little thread, I guess I'll keep it updated anyway. My new Powergrip posi should be on it's way today from Ron's along with a new set of ring gear bolts. I don't know who I talked to at Ron's but he was very cool. The prices can't be beat either.
