Hello, I have a 2002 Impala LS that has started to make a tinging or ringing type noise. This noise is produced when the car is in gear and rolling. The faster I go, the faster the tinging/ringing noise gets. Specifically I have to load the drivers side suspension (front) to get the sound to really pick up. I had thought it might have been a squealer on a brake pad, but I changed those to no avail. I check the steel clips that hold in the pads, and they are clearing the rotors. Everything else looked alright when I was under the car yesterday. Anyone have any ideas?
That was my next guess. I axle looked fine and I didn't see anything that was wrapped up that could cause the sound. When I was torquing down the lug nuts, I could barely hear the sound. Most of the wheel hubs that I have hear go made a loud, roaring sound. This sounds like a midget is under the hood tapping the rotor with a ball peen hammer while I am driving down the road.
I forgot about this post but wanted to add an update. It turns out that sheet metal shield for the ball joint was tweaked a bit and was making contact with the rotor. When the wheel was loaded, the contact was much stronger and thus increased the intensity of the sound. A few seconds with a big screwdriver and everything was back to normal.
