Its the front lower control arm. I got a new bolt put in but it only helped my problem a fraction. The wheels still tend to pull wherever they want to go. I have the feeling that some part of the linkages are loose but I dont know what. I already had an alignment and they found nothing wrong. As for the crunching noisewhen I go onthe brakes, I took of the calipers and the sliders were pretty stiff. I cleaned as best I could and then rubbed on a little grease, They slide a little better but when I push them in they still slide out very slowly. Is this normal or are they supposed to slide out immediately. I also noticed that the caliper piston seems to be rubbing an unevencircle into the back of the brake pad. I added a little grease there as well. The noise level has reduced but is still pretty loud. Any suggestions?
