hi, i picked up a used 05 ss/sc 2 weeks ago and i noticed today that a rattling sound was coming from the rear driver side of my car when i am between 2000-3000 rpms and then again around 3000-4000. i'm pretty sure that everything on my car is stock. i'm almost certain it is something to do with exhaust and think that it may be my heat shield that is loose on the muffler causing the rattling, but i am not very experienced with cars. Is it common for the heat shield to come loose on these cars? Also, what are some other possibilites that may cause this problem?

Thanks

 

i dunno about the ss/sc but mine came loose at 50kms the same day i picked up the car. but mine is a 2.4ss/na

 

very well could be a heat sheild. it's easy to check, get under the car and just feel around the heat sheild. if the sheild is touching either the body of the car, or the pipe, that's your problem. all you have to do is bend it away from what it's touching.

 

man, i have the exact same thing, no idea what it is, been goin on for about a month now but it doesnt seem to affect anything at all just annoying to hear it.. took it to the dealership and they supposely alligned the exhaust and heat shield? which did nothing.. so i gave up since its not all that noticeable.. hopefully when i get my new exhaust ill get it fixed.

btw if u get it fixed pm me and let me know how.. thanks

Why don't you just jack up the car and find what's rattling? Did you try what D4u2s0t recommended?

 

I took the car to meineke because i couldn't find where the heat shield was touching anything and the mechanic there said that he couldn't really hear the sound but he did notice that the catalytic converter was falling apart because he noticed little pieces of metal coming from the exhaust. do you think that the cat could be the cause of the sound i noticed? I'm taking it to the gm dealership tomorrow to get a new cat because i'm still under warranty.

 

could be, if you heard metal bouncing around. the cat is covered for i THINK 60,000 miles or something like that. they should fix it no problem.

 

does it only do it while driving or does it also do it at idle and while revving the rpms up?

 

I had my cat go bad and it makes an annoying rattling sound when It's going or gone. Drove me nuts till I finally broke down and took it to the dealership. I would get it replaced under warranty.

 

**** i think this might be my problem too... is there any way u can find out for yourself bc the dealer is actin like its the heatshield but it's still makin the noise?
