I have 1992 300e with 147,ooo miles when you hit a bump it feels like the car looses its grip.The car has continental tires with good tread left,I replaced the front struts.the front bushings look good,the front ball joints do not have any play by trying to move wheels in and out with car jacked up.In the rear of the car some of the bushings look a little dry-rotted but not too bad.Can anyone give me some advice? Thank you.
