asked by on

over speed bumps the back bounces more than the front. changed all 4 corners struts. but only changed the front sway bar links

My car has 230000 miles.
My car has an automatic transmission.

Rear sway bars are to help the rear of the vehicle to be stable when driving around turns or maneuvers and when towing another vehicle. The sway bar should not affect the vehicle when hitting bumps unless the links or bushings are worn or broke and even then they will mostly make noise.
