popping from the rear..... haha

[inferno19d]

Ok, my first of many noobish questions. I am getting a popping sound from the era end of my 2011 sedan. I have look under and around the shocks, sway bar, end links, etc and can not see any obvious issues. I have upgraded the tear sway bar to a pertinent 22mm and have yet to upgrade the end like.ks, could this be the issue? Your input is greatly appreciated.

When does it pop?

Does it pop when it's hot?

On a more serious note, try and record the sound from inside the car and then from out side of the car. If you cant see anything that might be rubbing or hitting then one idea is too push down on the truck/stand on the bumper/trunk and jump up and down, thus putting load on the rear end. If anything this should get it too "pop" again so you can start to figure it out. First step is always replicating the problem.

I have popping on mine and i'm reasonably sure it's the swaybar mounts.

I've got every noise you can think of coming from mine, first bushings, readjust end links...tighten...what do I know.

 

[IGOTASTi]

Strange, lol.

I have tried to replicate the sound while the car is stationary and I have not been able to. It does not make the sound when it is 95 plus in temp. It seems to do it more the cooler it is outside. I have pushed up and down on almost every inch of the car trying to see if the popping is coming from the shocks, struts or the mounts with no luck.

Try removing/unbolting the sways for a quick trip. This will make your car handle VERY differently, so dont push it. But if you still hear popping, it's not the swaybar.

My car pops from the rear when I floor it then step on the clutch...:tard:

I agree with the others and checking the area's you've modified/ upgraded first.

I am going to put it up on a lift tomorrow and re-check the areas I modified and then go through the process of trying to trouble shoot the issue if i can not see anything... I was just looking for ideas of anything else it might be.

Yours sounds more like when the rear struts start clunking in the old GDs...

Nope, pretty sure there are other factors to the clunking, clanging.

Sounds like the common drivetrain clunk, upgrade bushings and use subframe bolt kit

Coming from the rear? Check to ensure proper clearance of the exhaust with the other components. That Perrin Exhaust has that collar that is used to hold the exhaust over, we have heard about these sliding letting the exhaust to interfere and clunk/clank.

To the Original Poster, When do you notice the noises? on turns, accelerations, braking or what?

The popping sounds from the rear end sound like they are echoing from the trunk... I have only upgraded a rear sway bar. The popping doesn't come from the up and down motion of the car, more of the side to side movement. So I am thinking it is the actual mounts or the end links. I had it up on a lift and could not see a damn thing wrong...

Just so you cover all bases, check your rear axle nuts and re tighten them.
