I fixed this problem by trading in my 2010 Camaro for a 2011 SS with the revised strut towers. Been over every road surface that used to make my 2010 sound like it was falling apart and not a single issue with the 2011. GM wouldn't have redesigned the strut towers if there wasn't a problem with the initial design used in the 2010.

I am glad the noise is gone, but the mount is the same 2010 to 2012.

There is a 'loose lumber' TSB for the Mustang and the Mustang has a bolt in strut mount.

I said strut tower, not mount.

So, you are saying these are the same?

2010 to mid-2011:



Mid-2011+:

Mid-2011+:
The fender structure you see under the hood is clearly different in the model years. The actual mount, the strut mount bearing plate on top of the strut that fits into the body mount is the same year to year. It has not changed in mounting style or function from 2010. What I am saying if that if it were the strut mount cuasing the noise there is no reason to expect any change.

The reason for the changes in the towers revolved around the development of the Vert. The Vert introduced the strut tower bar, the under chassis braces and revised sub-frame bushes. The strut assembly has not changed It still uses a reataining plate to keep it in the car when lifted or airborne. The strut reatining plate still articulates. The strut retaining plate rubber still leaves a 'wear' mark underneath it.

Short answer -- yes the mount is unchanged

I can't speak for GM and won't. I can an all too often do offer my opinion on a variety of C5 topics

I personally have done between 50 to 60 ZETA suspensions over the last four years. More than a few were making front end noises when I became involved. Aside from the strut hydraulic whoosh, they have all been resolved. I am not aware of any design flaw and don't feel there is one. That doesn't make me right. A bad bush here, a ball joint there, failed endlink, loose CA, ball stud, endlink, RA nut, sway bar strap nut do not combine to define a design flaw. I have yet to see a failed Camaro strut / mount bearing plate, though I have seen quite a few in the G8. That is why the mount was redesigned for the Camaro. The G8 mount was a carry over from the Holden Monaro and long over due for an update.

By now you know I call it like I see it. I don't believe the redesign of the towers has anything to do with the noises that have been reported in this thread and others. Once again, that does not make me right. It is just what I have seen first hand and my Dealers report to me.

Just did a scan back through the main suspension noise thread...and noticed that nearly everyone complaining about these sounds had a 2010 or early 2011 model. Finding it odd that this issue has died down for the most part and no one with a late 2011 or 2012 model is complaining of suspension noise.

As noted in my posts there was a running change made to the upper insulator -- Flat rubber ring to steel with urethane.

When I had mind to the dealer he compared my 2010 with a 2011 on the lot and said the same issues were on the 2011 models.
So are you saying the strut tower revision really didn't do anything to correct this problem,if so why would GM have changed the design.
Thanks for all your input,I don't want to trade it and take a big lost in the purchase of another 2011 and end up with the same issues.
Other than this annoying noise the car is fine.
IMO, speaking only for myself, GM redesigned the towers to compensate for loss of strength when the roof is removed on the convertible. It is the same reason they added a strut tower bar and the cross bracing underneath. They all compensate for open air motoring. The constant between the front ends in regards to noise is the strut assembly Strut, coil, insulator, washer, upper spring perch / bearing plate, washer and nut. Once in the car a retaining plate and nut are added. Upper insulator aside, the design is not changed.

I do know that the Camaro strut mount is designed with a bias toward performance and durability at the expense, to a degree, in Noise, Vibration and Harshness (NVH). Given the performance numbers we achieve in our Pedderised Camaros and the Ring time of the ZL1 they gave done very good job. None of that addresses the pain in the but noise some experience. My frustration is I really believe our process works from replacing the upper insulator to making sure everything is tight.

Will GM replace this in a TSB issue, if I requested it or will they again say there is nothing wrong with it.The strut assembly would have to be removed to replace this insulator.is this correct?

Thanks for all the support
I have not been able to locate a TSB on the black flat rubber ring replacement with the new steel and urethane insulator. That said, I have personally worked with three different Chevrolet New Car Dealers to resolve front end noise by doing exactly that. It worked.

Cheers
Again thanks for all the advise and help in trying to solve this problem.
The strut does have to be removed to install the new insulator. The way I found out about the upgrade is we ordered a couple of mounts from GM to have on hand for R & D. When they arrived they had the steel and urethane insulator. We double and triple checked with GM and found the new style had superseded the old style. You can't buy the old style rubber insulator from GM. I am at SEMA and have asked the guys at the office to dig up the part number.

The pop/thump sounds may have something to do with the gap between the top strut retainer and the strut tower. My experience was, when I jacked the front up I would sometimes hear a mysterious thump or two. Couldn't find anything loose but I noticed that the gap between the strut tower and retainer was not there with the front jacked up. Trying to find out if this gap was normal, I ran into this thread...
