popping in front end when I hit a bump

As far as I know, GM is still investigating the noise.

I can tell you that we are seeing the upper strut to spring grommet tearing on OE struts on a regular basis. But all the ones that I have seen do not have a noise complaint. In fact, I have not driven a Camaro with any front end noise issues. Guess I have been lucky.

But GM is working on it. Has been a while and I do not think they have updated it as of yet.

This noise is not supposed to be there. My dealership resolved my issue after three attempts.

I had the sound turning left from a stop. after numerous attempts to fix it, the GM engineers told the dealership the struts, and the whole strut assembly needed to be replaced. Afterwards, I have been clunk free for three months.

See if they will do this for you.

Mine's not stock, but I eliminated a bit of the noise. I found the Pfadt rear end links on the lower frame were only hand tight!! They sure did loosen up from when I installed them! The upper rear end links were a bit loose, but not that much. Front were good and tight, but one side of the Pfadt sway bolts were loose. I guess I missed that one the last time I tightened it all up. Also, the passenger side end link was kind of twisted, so I straightened it out and that stopped a lot of the popping on the front right side

Next time I will be removing all the end link bolts and loctite them :( Didn't have the time this past weekend. i can't bring mine in for any suspension TSBs or otherwise since there isn't much left that's stock!

mine is in for the same front end noise that only happens when I'm going over a road that's bumpy. Something rattles like it's loose.... single bumps don't hear anything. I drove the car with the service guy in it and he heard it. Let see what happens

Can you look at your invoice and list the p/n of the replacement pieces for us.

Mike, not sure if you're directing that at me as I don't have OEM replacement parts, mine are all Pfadt components. And the coilovers are KW's.

Thanks,

But when I turn into my drive way (which is on an incline), it does it. Or the occasional slow speed pot hole/speed bump. Real annoying, makes the car sound cheap.

Mine also has this same problem. I have been watching the many post that relate to this problem for almost a year while I wait for a fix from GM. This is a specific noise you can hear but also you can "feel" it in the front end whenever I drive at low/slow speed over speed bumps or pot holes. There is no evidence of this same problem in the rearend, just in the front and it is getting worse. Also, there are sounds and popping noises when I turn into my driveway, which is also on an incline. It makes the car feel cheap and not put together very well. I also do not beleive it is a normal characteristic of the suspension or frontend.

I have taken the car to the Chevy service dept. several times--the most recent was last month when their tech reported the problem could not be recreated/heard. Initially they did hear the noise and when compared with new Camaros on their lot they also heard it. But I was told there is no fix for the problem and so I would have to wait. I'm still waiting.

By the way I am also still waiting on a fix for the hesitation/poor/jerky acceleration at lower speeds. And now the OnStar (when trying to make a phone call) causes the radio to freeze so that it won't shut off even after the car is powered off and key is pulled. The radio sits for hours apparently powered on, with no sound but the display is on as if it were tuned into a station with the volume turned off. Cannot use OnStar at this point. This problem started after a fix/reprogramming was done for the air conditioner.

If anyone has luck with a fix for the front end popping/klunking noise I would love to hear about it.

GM has PIE0054A out there since March 29, 2010. This is a info sheet to the dealers telling them to contact them when they have a clunk, pop, or rattle in the front end that is not obvious. So GM is still working on a cause and fix.

I roadtested a Camaro where the owner would turn the steering wheel as far as it would go, and back out the driveway. This caused a noise that is really not that fixable. The are on the spindle stops and metal to metal. Hitting a bump creates metal to metal vertical contact. Adding a little grease there may help. I know this is not everybody's issue but is just one specific example.

thanks

I have just returned home from an afternoon of shopping for a new car. I won't accept this and the other problems mine has. Especially since I have had these issues since the car was new about a year ago. I actually gave the Dodge Challenger SRT8 a good going over but I hate that the only interior scheme includes black leather.

This is my third Camaro, second SS and I am so very disappointed. I love this car's look and still hate to part with it. But I enjoy driving way too much to drive a car that "bothers" me if you know what I mean. If only Chevrolet understood that most of us who bought these cars are picky down to the gnatt's ass about how our cars perform.

Gm will find a fix for the clunking and popping front end problem faster if everyone with this noise will take their car into their dealership and ask for TSB PIE0054A.

Also ask that the engineers be called as directed by TSB PIE0054A.

No action gets no results.

You are on the right track. I think the challenge is potentially getting lack info from the dealer.

I have 3000 miles on my RS. At about 1200 miles is when I started hearing a clunking noise on bumps at slow speeds coming from my drivers side front. Took the car in, and dealer told me they couldn't hear it, and sent me on my way. In the mean time I have taken it to 3 different mechanics, and they have all heard it. Have taken it back 3 times, and each time they can't hear it. Last time I road with the service writer, and I could see his facial expression change when he heard it. They had my car up on the rack for 2 hours just to tell me they couldn't find anything that it must of just been tire noise, and that it is normal. When I read a copy of the ticked the service writer had put on there that he did not here it on test drive. I call bull poop on that. He also told me that all the print outs from this forum didn't mean squat to GM, or that dealer. I have talked to a rep from GM and they told me "You have to take it up with the dealer".

I was born, and raised in a Chevy family. My pops is a retired Chevy mechanic of 50 plus years. This is realy putting a sour taste in my mouth, and don't think I will buy chevy again.

You do have other alternatives. If you look in your owner's manual, there is a section on how to resolve disputes. You should contact GM customer relations and explain your concerns. Ultimately, you can seek 3rd party arbitration through the BBB. You will have to demonstrate the noise to them.

Follow up report. My car will be one year old this Saturday with 9200 miles on it, and the noise started after about 300 miles. It continuse to this day. I have had it in several times and had strut mount TSB performed. Still they tell me there is no "fix" yet. Keep asking your dealers !!!!!!!

On the other hand.... I know the noise is still there, but I hear it less these summer days with the sun roof open, windows down and my "driving music" playing throught he sound system. I really dread those cold fall /winter days when the windows will be closed and the noise will be once again, irritatingly evident.

Let's keep bugging our local dealers! They fixed my transmission bolt "back-out" problem, I know they will eventually fix this too.

Thanks! KenCarGuy
