Need help guys...ckunk sound when coming to a stop

[Doubeleive]

And he told me 7 1/2 hours labor to do it. That doesnt sound right to me. A rear end replacement shoukdnt take that ling right?

no it doesn't take that long I would guess closer to 4-4 1/2 (roughly) the wheels have to come off then the calipers, rear sway bar, then the rear cover, pull the pins and axles out to get the carrier out. maybe more time if the pinion needs to be done as well.

Thats about what I thought after watching some videos. I think im just gonna buy a whole new rear end and put it on. Heres a question though whats a good gearing for a rwd? 3.73? Or 3.42?

@swathdiver could probably give you more info on that, I guess it really depends on if you plan on towing with it or not. but you shouldn't be having to replace the entire rear end unless it has 300k+ miles or has some other issues going on there pretty hardy and just replacing gears bearing and seals usually get's it down the road for a long ways

It has 208000 miles probably wont tow that much but i plan on trying to make it quicker down the road, not drag fast but quick you know? I was just wondering what ratio would be better. I wanna go ahead and just put a whole new deal in it just to be safe. All the ones with 3.73 say 4wd only, but then say it fits my submodel so idk. Mines rwd so idk if that would matter since. Idk the difference on a rear end made for 4wd and one made for just rwd

Yeah, even at 1,200 for a stock rear end rebuild is still questionable, they better be putting a good selectable locker then I could see it and a new quality gear sets. 650 to 850 would be more reasonable. Now 1.5 to 2k that better include the reach around.
373's is a nice compromise, even better and less of a headache since you wont have to regear the front diff since you don't have one What gear ratio do you currently have?

Thats what im not sure. I bought it used. I think i checked and it said 3.73 but im not 100% all the 3.73 says its 4wd only. All tje rwd say 3.42 and all the prices i say for all new are about 1200 to 1600. But idk exactly where to shop for one besides jegs or summit. This is all new to me lol

 

[Erickk120]

You can get them rebuilt at some reputable shop, its faster and as long as they know what they are doing it might be even cheaper, Really depends 4wheelparts would be a good start, I would give them a call and see how much they want for a regear. Regear pretty much means new gearset and bearings pretty much everything in the diff, outside of the carrier and axles, do you have an open diff or g80?

there should be a rpo list in the glove box that list describes all installed features on the vehicle, you can google for definitions or just post a picture up on here.

If I'm reading those codes correctly, it's a 3.73 ratio, posi locker
