When I brake it vibrates very bad. Also when I make a right turn and hit a fairly new curb or high curb like my parents drive way the right front tire sonuds like it is going to rattle off. Is it the lower control arm and ball joint?

The locknuts were rusty and one way and hard to get off. I ended up pulling out my grinder it was a nightmare. And despite the part stores insistance the bushings were right they weren't. (Thank you canadian tire) Drove it 15 miles the noise is back without the vibration. Do I change the bushings next? And I know I have done them at the same time as the link!
