For years now, there's been a rattle coming from under my center council. It ONLY happens when the car is in gear but stopped. It could only be heard in the car, not from under it or under the hood.
At first it wasn't too bad so I didn't pay much attention,then last year it started to sound violent. I crawled around under there and everything looked good, so I changed my transmission mount over winter thinking that might be causing the problem, after doing some tech searching and asking around on here. I was worried it was something that was going to cause more problems down the line. When I got the car out for the year it helped slightly, but the rattle was still there.
I realize exhaust would be the first place to check, but for one the rattle was there with stock exhaust and didn't change when I installed my LTs. Also I didn't think it would have been getting progressively worse if it was exhaust, it would be more consistent.
I now have Pacesetter LTs and ORY and there's at LEAST 3/8 an inch seperation from everything else on the car.
I finally got fed up and put a piece of rubber hose around a clamp to see if it was banging somewhere and moved it to a few different locations to pinpoint it. finally, I cut a piece of hose and flattened it out and wedged it between the exhaust crossmember piece behind the transmisison and presto! no more noise!
I realize it should have been one of the first things I checked, and will pry be flamed for not doing it sooner, but had to share my good news! It was annoying the hell outta me.
