Rear deck tick/pop
 

Guys,

Looking for some advice on the matter. I had the rear tick/pop issue resolved under warranty at the dealer. The issue has come back after one month...however now it's really random and happens once in a blue moon. I particularly notice it when I throttle out of a corner and get the chassis to flex.

Anybody have recommendations on how they resovled this issue? I read something about a chassis ear that helps. Is it worth chasing the issue down? At this point my car has problem been torn apart many times - which I know can lead to more rattles.

I was thinking of maybe just living with the issue for now until I dynamat the rear trunk area...but I hate covering up problems.

Have you tried using WD40?

I tried to myself and the issue didn't go away. I think mine was more major and required separation of panels to stop the ticking.
It's at the dealer now...there is a Canadian TSB on the matter and they are performing that regardless.

Try putting the rear seat down and see if the noise still happens. If it stops, then it might be this.

Ya I'll have to try this. The only thing is the sound is not a single pop/click sometimes its pop pop click tick etc.

The dealer may have followed the TSB for rear deck pop but didn't crack a weld spot enough or get all of it so you still are left with part of the issue. Or not enough grease was used.

I still had the popping/clicking in the rear even after doing the TSB fix. It would stop popping if the rear seats are folded down. It turned out to be the rear seat. This fix worked for me: http://www.ft86club.com/forums/showp...0&postcount=30

Lower rear seat then slowly position it near closed and use your fingers to feel underneath if the gap is even. I used the "flaps" on the rear of the seatback to gauge the space. The flap on the driver side of mine was touching the rear latch while the passenger side was not, meaning the seatback was uneven. I just loosened the 12mm bolt in the photo shown in the link, pulled the seat forward, then retightened. Problem solved, easiest fix ever.

First you need to make sure that the rattle is really coming from the rear deck.
I suggest you ask someone who is small enough to sit at the back and try to listen where the rattle comes from. It might be not from the rear deck.

There is separate thread in issues/Warranty/Recall section about this.

I'm assuming it is because the sound it's making is the same as before where the fixed my rear deck and it went away for a month. It's a pretty distinct sound but I could be wrong.

Hey so i checked my setback and eureka the flap is touching on one side and not the other...the setback is definitely installed unevenly.

Here's the tricky part to me though...when i dropped the seats I actually heard more noise but it sounded different. Is this normal?...I imagine the seats up adds some rigidity vs them down.

This makes me think that the noise actually is coming from the rear deck. When my rear deck was making noise, the noise got louder and sounded different when I put the rear seat down. I think what FiRStsc10n said is true for your case.

I would try to get as much spots as possible from inside of the trunk and see if that gets rid of the noise. Kind of like this.

If that doesn't get rid of the noise, then either you or the dealer is to remove the rear deck cover and get the rest of the spots from the top. Like this one.

So i went for a drive and I still hear ticking...so I think you are right. Did you crack the welds yourself? Dealer has visited the issue twice and I doubt they cracked every weld...it sounds like guys have cracked 50+ welds on their own.
How do you know which welds to crack? All of them? lol.

If they already had tried 50+ spots instead of just the 2 spots shown in the TSB, then I wouldn't try it on my own. I would bring it to them one more time and see what they say.

I was lucky that mine had only one spot that was making noise, which is here:

When I pressed the red circled spot with my thumb, it made the cracking sound. I just sprayed some WD-40 as shown in the picture. The noise didn't come back since then and it's almost 2 years now.
