Pushing on the Rear tires.......
 

I was thinking that maybe you guys could give me your opion on this.........

I noticed that when I am driving the car and when I pass over some bumps or pull out of the driveway, there are some pretty good sqeaks happin'in :(. So when I pulled the car into the garage, I placed my foot on the rear driver side tire, and pushed inward. The result was a sqeak or grind noise. So I pushed the passenger side tire and the result was the same.

I'm not a mechanic by any means, but could the noise be from dry ball joints or anything like that. Maybe the rear axle may need lubing??? It's a pretty good sqeak!!!

I just wanted you opions before I take it some place and have them charge me up the wazzzoooo...........

I know Mustangs are generally filled with rattles and things, but I think this could be something more serious.
