Please help me identify this noise..

[flexion]

hola!

I need a little help from the lx community ;)

My 300c started to make strange noises, and it gets worse every day. I think the noise must come somewhere from the rear right suspension, maybe from the KW-v2, I don't know exactly.. you can hear it on every little bump in the road and it sounds like something is seriously broken.
Today I went to the chrysler dealer, he checked all the bolts on both sides, and also the exhaust, but everything seems to be okay.. he couldnt help me and after nearly one hour he gave up..

here's a video of that noise: (well, audio quality is not the best, but you can hear it @ 0:01 / 0:10 / 0:16 / 0:20 and 0:29..)

it is much louder when you sit in the car.. the microphone of video camera isnt really HiFi capable ;-)


you can't hear much in the second video, there are too many background noises, but I uploaded it anyway:

Outside.wmv (http://homepage.swissonline.ch/swissoffline/skit/outside.wmv)

any ideas what kind of noise this is and where it could come from?
does this sound like a broken damper?

thanks a lot! :beerchug:

Check out my post dealing with an issue I just resolved. I took it to a dealership too, and they checked everything, but somehow missed the sway bar end link bolts that ended up being the issue.

Well, my issue was with the front.
The sway bar end links require a 21mm open ended wrench and a 10 or 12 mm socket. I put a breaker bar on it so I could get tighten the hell out of it. Fixed the problem for me. Just putting a wrench along on the nut won't let you turn it to tighten, you need two wrenches or wrench and ratchet to do it.

Did you upgrade your sways? Maybe the sway brakets are loose.

Also, check your rear Cradle Bolts. I put a 2ft long breaker bar and tightened them suckers down as hard as I could.

Hopefully you find your problem! Good luck!

thanks for your input! I'm glad you got rid of your annoying noise ;)
I think I will take the car to the dealer again to check that, but I will wait until one of the other service guys returns from holidays. I dont want the same person to look at it again and pay for nothing.

I have replaced the front swaybar bushings twice in 107,000 miles, when they go you hear a terrible clunking, it sounds like the wheels are going to fall off. I have had Japanese cars that wore the rear bushings and they sounded as bad. Grab the bar where it goes thru the bushings and shake it. If thats it, the bushings are cheap and easy to replace.

update: today I went to another chrysler dealer (http://homepage.swissonline.ch/swissoffline/skit/300c-kw-kaputt.wmv), but again, it was a waste of time. there must be something wrong with the KW dampers.

tomorrow I will meet with the KW guys..
damn, 13 months old KW-v2, less than 10'000km and already broken!?

There could very possibly be something wrong with them. If there is, I hope KW takes care of you! Good Luck!

back from the KW shop. still clueless.
got a 4th appointment next week to put stock suspension back on it...

omg my AWD car will look like a russian tractor without lowering.

damn.. this really starts to s*ck.

update: removing the KW setup didnt help, the noise was still there. WTF!
but now they found out the noise is coming from the driveshaft.
paid 400$ for this analysis.. but I still got that annoying noise.

argh...
