So doing my header install I noticed the inside of the passenger side tire is wore out like the car is riding on it. The car has stock suspesion on it. Could this be a bad strut? The car has had an alienment done before I got it 2 years ago. When I drive the car I do notice a knocking noise from that side. Or if i push down on the car i can hear that strut making a knocking noise. Bad strut??
