The car was fine then I jacked the rear up put it on jackstands, swapped my Macs out to Flowmasters to see what it would sound like, which sound 10 X worse than the Macs (too bassy) but ever since then when I pulled out of my driveway I was going straight and I turned left or right and it seemed to almost been sticking and it "clunked" out of the center position, kinda like something was holding the wheel up then it let go and then started to turn the wheels. After it does it a few times it goes away but it comes back after I park and go to drive again, I'm afraid my steering's going to lock up or something. Any ideas?
