Hi, I'm trying to help diagnoise a problem my good non mechanically inclined friend is having with his F250. whenever your driving it and hit a small bump at slow or high speeds you here a thump or rattle in the front end like something in lose or worn. you can feel it in the floor boards slightly. i've done some searching and the only other similar sounding problem i saw in another forum was the cab mounting bolts were loose. Also if it makes a difference this truck has about 95K miles on it. thanks in advance

it could be your sway bar bushings on the front end

 

try tightening the shock absorber mounting bolts

 

try getting your ball-joint check. i have the same thing and had the same problem, new ball-joints no more problem
