Noob needs some quick rear end help
Noob needs some quick rear end help Ok so I bought a good used differential with 3.23 gears 4 channel from the classifieds here in ls1tech, I have a 2001 z28 that I want to swap it into which has 2.73 gears, Im going to swap the whole rear end, just wondering how hard will it be?? Any precautions I should take?
I also want to freshen up the rearend, what should I do before I install it??
Thanks

depends how much you want to do.
I'd AT LEAST put a new cover seal and new diff fluid in it, scrape off any grime n rust, clean it up and give it some paint, move your known good brakes over to it, get new brake lines on it.
Are you sure it's not an open diff? Reason I ask a lot of 3.23s came on v6 cars and could be open diff rearends. I have a gu5 3.23 rearend under my parts car, but I haven't been in it. It spun a tire recently (just one..) so chances are good.
if yours does have a limited slip you don't have anything to worry about there, but.. just check it for leaks, make sure your front seal is good. If you're savy with this kinda thing you could probably put new bearings in it, but I think they gotta be pressed in? depends how much life you want outta this thing I guess.

as much life as possible but if I put new bearing I guess its a little harder task no since I have to remove the axles I believe??? Also was planing on changing the oil and gasket but what kind of oil???
diff fluid. 
I'm not sure a certain brand, someone else can probably chime in there.
Yea, you gotta pull the axles to get the bearings out, and you gotta have a puller or a LOT of patience to get em out, if they work like the old 12 bolts that is. I haven't been inside a 10 bolt yet. I don't think you'll have a bearing failure without knowing it. so it's probably not REQUIRED.. it's just easier to do when the rearend is in the bed of your truck than when it's rolling down the road. plus if the bearings go bad you may need axles.. BUT.. your 2.73 axles will work as spares there so no worries.
I think new fluid and seal, clean it up, it should be good to go if it's limited slip already.
I was kinda thinking about pulling the LSD out of my 2.73 and dropping it in my 3.23, but no idea how feasible it'd be.

Sorry to revive this thread, of course If I posted a new one I would get
But most v6 car's came with a 3.08 gear not a 3.23. Some came I believe with 3.42 "RS?"
having said as much, I have 3.08 in my V6, with ASR. I want a 3.23, it's not a big difference but it will help to do with it what I want. Any suggestions on gear sets anyone? And I would like to keep the ASR if possible...
