I just replaced front end, lower and upper control arms, ball joints, front sway bar end link, outer and inner tie rod ends. New brakes and shocks all the way around. Now, when I drive there is a popping and rattling sound from the slightest bump in the road. It wasn't doing this before the parts change. I don't think I have anything loose that I have replaced. I sprayed WD40 on rear suspension rubber and bushings, to see if that helps, as those bushings are worn and need to be replaced. Didn't help. Still pops and rattles. Any thoughts on what to check?
