Saturn SL2 Problem
Average Mileage: 130,000 mi (100,000 mi - 160,000 mi)
I'm pretty sure all cars with lots of miles on have this problem. I replaced all 4 struts and now my car drives awesome!
Note: I did have to install 4 "shims" so the car would pass alignment. A shim is a special bolt that is sort of wobbly in the middle, it lets you adjust the angle of your struts just by spinning the bolt.
A little weird, but my car drives better than new now.
