If you've changed anything with your spare tire recently, it can easily be rubbinng on the metal. Mine has done that, and its an easy fix.

Hello
He's right! When the bushings start to dry out they start to squeak/clunk. If you look into it I am sure that is what it is. Either time for new bushings or just upgrade to newer lower control arms and pan hard bar with grease able bushings so that will eliminate this problem! If you have any other questions feel free to ask and I will be more than glad to help! And I figured I would put a link below to show you what all UMI Performance has to offer as far as rear end packages!

Thumbs up

Glad that you like the products! And thanks again for the business.

Hello
Seeing how it is a daily driver and it is stock ride height (correct)...? You will be fine with non adjustable parts! But if you are planing on lowering the vehicle or going with a bigger wheel you will need adjustable parts, doing so will allow you recenter the rear end or the wheel. If you have any other questions feel free to ask and I will be glad to help!
Thanks
Brad

if it sounds like its coming from the brakes, first thing i'd check would be the lower control arms. at least whenever they made noise for me, it always seemed like it was coming from there. make sure your bolts are on tight. if they're not loose and your bushings are shot... might as well upgrade your lower control arms.

Don't forget about the shock in that location too. Could be worn out.

Its your rear end, but dont be scared you just need to change the fluid. Get it changed out with synthetic and gm posi fluid and it will cure this. Same thing just happend to me.

Bro my car is making the same exact sound at low speeds on bumpy roads sounds like a creek its really annoying. Just bought new sway bars put them on and when i took off my tires to check if it was my bushings they were tightened so hard that the bushings are misshaped i think i should just buy all new sway bar bushings. Dont think my case is the grease i think it could be my bushings what do you guys think?

my rear LCA bushings were shot, and made all kinds of noise, some moog bushings ($55 or so from the autoparts store) and it's better than new back there. (1le style full rubber vs the waffled stock stuff)

While I was back there, i did replace the swaybar end links, and swaybar mount brackets with poly pieces, and inspected the panhard bar bushings, they looked fine. My bilsteins only have 15K miles on them, so the mounts for them are fine.
