the car was bouncing all over the road. the car made noises the rear. it would shudder as you hit every pot hole. what happened was the seal in the strut had let go in the rear causing the spring to take the full load and suspension. so i changed all the struts in the car. the struts are only good for 60K miles. Its really it considering it has a sport tuned suspension. all bumps are still hard with new struts from ac delco. i need to change them again at 190K. once again this car has shown what a piece of crap that it is. i have dumped to much money into this car. its not a lemon but it might as well be.
