i drive a 2009 civic lx-s. last spring i hit a fairly large rock in the the road which threw off my suspension and bent the drivers side knuckle, after getting that fixed and the car aligned ive noticed that the rear tires are almost completely bald. the wear on the rear tires is even and there is no feathering. at highway speeds when the car hits standard bumps in the road the rear of the car sways to the left. anyone know what this could be?

 

start by replacing the bad tires. start with the easiest and safest problem.

 

was there anything abnormal in the alignment after you replaced the knuckle?

i think you need to have the car checked out again. theres still something wrong.
