problem #1

Sep 302008

G6 3.5L

  • Automatic transmission
  • 19,884 miles

I bought the car used with 30,000 Km on it. Three weeks after I bought the car it developed a squeak from the rear drivers side wheel. Whenever going over small (at normal city speeds) bumps or speed bumps at slow speed a distinct high pitched squeal can be heard.

The dealership can't seem to find anything, when they lift it off the ground (on the lift) the squeak goes away for about a week, then comes back. They have tried hubcap gaskets, replacing clips in the rear bumper, greasing the parking brake cable to no avail.

The squeak isn't present when the roads are wet.

I am convinced it is something in the upper suspension as it is most present when going over a speed bump at low speeds. As soon as the rear tire starts to travel up the speed bump it squeaks.

Any thoughts would be greatly appreciated!
