I have a 95 F150 that vibrates wildly on the right hand side at about 40mph if i happen to hit a bump. i have replaced the bearing's and the tires. Everything feel's tight underneath. the shock on that side seems to be good and the spring. any ideas?

 

have you check your ball joints? and does it cause steering issue like the wheel does a slight rapid left to right and back motion?

 

it's a severe up and down jumping.
