I started hearin a squeeking noise from the rear driverside. Now it is louder and heavier. Any ideas?

Gonna have to hold your computer closer to the car so I can hear it! :)

The place to start is with an inspection at a tire and alignment shop. If you want to try to find it yourself, there is a tool you might be able to borrow or rent from an auto parts store that borrows them called the "Chassis Ear". It is a set of six microphones, a switch box, and headphones. You clip the microphones to suspect points, then drive around while listening with the headphones. You can move the microphones around to zero in on the source of the noise. Be aware that many mechanics have never seen or even heard of this tool. Suspension and alignment mechanics use it to find rattles, squeaks, and other noises.
