There is a squeek that comes from the driver side area (maybe under the car?) when I either get into the car or hit a bump or something that causes gravity to weigh down my car momentarily. What could this squeek be coming from and how do I fix it?

 

could be a bad bushing somewhere,like upper/lower control arm,maybe a sway bar bushing,could be the springs in the spring pocket macking a squeak noise,its hard to tell.

jack the car up,put it on jackstands and try to move parts around,maybe jack up on the tire a little bit to see if u get a squeak outta any of the control arm bushing or the spring.

-OR-

drench the whole underbody of ur car in WD-40
