Knocking noise in frontend of 2007 saturn 2 when going over bumps slowly. why?

SOURCE: Passenger side "clunk" from front wheel while turning

Check your sway bar link kit and sway bar bushing also check control arm on passenger side . It could be one of them , they can make noise if they are worn out . It happened to my car too and I fixed the problem.

I agree. I see sway bar links go bad and make nosie much more often than struts on Ion's. Take it to a service center you trust.

This one really fires me up! First go back to Discount tire and "speak" to the manager. Tell him you want the actual problem fixed and that you want the cost of that repair subtracted from the cost of the tires since you didn't come in to buy tires in the first place. If he won't agree to that, DON'T pay them any more money to take pot-shots at fixing the problem. Take it to another shop but make sure to let him know that you'll be contacting his regeional manager, the BBB, and your local news papers consumer rip-off column writer. That said, it's very possible, depending on the miles on the vehical, that you may have a worn or bad ball joint or somehow something in the suspention has come loose, ie: pitman arm, control arm, shock, etc... The only way to know is to have a reputable professional inspect the front end.

it is the intermediate steering shaft. there was a bulletin but no recall on this. there is an upgraded part that needs to be installed

bad strut mounts are a common problem with the aura
