HELP!!!!!! Weird Noise

Aight, I lowered my car back in June and i'm assuming this is the problem. My Rear Drivers side Tire/Rim/Spring etc... That area is making a crunching noise when im driving but only at a certain spot when the tire turns. I'm not for sure if its the spring or what but it sounds like plastic crunching. Its hard to explain the noise exactly. When i took it in they have no clue whats going on. I looked at the spring and I dont know about anyone else i can move the back springs with my hand. I dont know if that is common with lowering our balts. Anyways i looked further and those 2 Circle Pads that go above the Spring have been punctured by the spring from being wet and is ripping now. Has anyone had this problem or Am I the only unfortunate one?

Found This post by a member on a diff site.



Hi Guys,

Thought I would let you know this issue has now been resolved. The reason for the delay was me being away and a few other things came up so it took me a while to drop the car back to them.
So I took it back to Peddars on the weekend as they decided to replace the rear spring to see if that fixed the issue. They jacked the car up and found there where a few rocks between the bottom suspension mount and the spring (apparently this can cause some noise and it seems it was an oversight by Holden not to add a rubber seal there). They cleaned the rocks off and added some more coil wrap to the bottom spring.
Went for a test drive with the manager and the noise was still there, he advised me that the noise wasn’t coming from the springs (previously when going for test drives with the manager the noise hadn’t been audible which was how it always seems to be when replicating an issue so I was glad that it was noticeable this time).
So they did a shock test on the car and put it back on the hoist to give the rear a check over. They found that the rear brake caliper was a bit loose and tightened it (but this may have just been because my pads are low). What they also found which seemed to be the culprit was that the Lynch Pin was loose (Think that’s the name of it). The area where the rear sway bar connects to the body of the car was loose on the left hand side and made a noise when moving it, this was tightened.
We went for another test drive and noise has now gone which is great news. Hopefully the lynch pin isn’t screwed and just needed a tighten, guess time will tell.

Thanks has to go to the guys at peddars for there time and patience.

jeliza had a problem with a spring cap not to long ago. hers was taken care of under warranty. i havnt had any issue with them since i lowered. and i havnt heard of this being an issue. prolly just a freak thing. they couldnt be that expensive to replace if you can find one in a junk yard. if it happens a second time id be worried about it.

Does the noise only happen when turning at low speeds? If so, go on an empty street at a low speed and turn the steering wheel left and right quickly, to see if you can replicate the noise that you hear. It also sounds like you could have the same problem I have. I looked up an TSB on this and it said if you hear a "clunking" noise when turning a low speed then you may have to replace the intermediate steering shaft.

Nope it does it constantly. Picture this maybe a locking nut inside of a cap cover bouncing around at certain spots when the tire turns. It does it when i drive straight turn etc..
Does it sound like it is coming from the center of the car?

Nope its coming from the rear driver's side tire
The best thing you can do is either have it diagnosed or just take apart the rear driver side spring and shock assembly, inspect everything, then put it back together.

Yea thats what i think is the problem cuz i just took off the brake drum and inspected my caliper and it looks fine. I looked at a lot of sites and forums im guessing on Cobalts that the rear springs are sometimes smaller then the stock so that when they sit in there they can move around out of the place where its supposed to be. IDK if that is why

Dealer will charge you about $95 for a diagnostic that will go towards the repairs, if there are any. Other places vary, like $65 or something like that, but also go towards repairs too. If you do go somewhere else request to have a mechanic sit in the back seat or where ever and have him listen to the noise that you are describing that way he can quickly identify the issue and fix it.
