When I drive my car, I've noticed that the back end bounces back and forth. This is most noticeable when driving at lower speeds, 20-30MPH, but I can feel it at higher speeds. What could be the problem?
First check your lugs nuts to see if they are tight, have the wheels balanced, I suspect one or both are out of balance. How are the tires? Worn unevenly? Maybe worn shocks?
First thing to check is lug nuts, tire pressure and condition of the tires.
Go behind you car, preferably with a helper, and push down on the rear bumper with all your weight, hard push as possible. The car should go down, come back up and stay there. No or VERY little bounce. If it continues to bounce up and down, your shocks are bad. '07 Altima has shocks on rear and struts front
