i have a 2000 f250 4wd with 7.3l about 2k miles...... there is a vibration in front end while driving from 40 mph on up during braking the front end will bounce between 45-40 mph there is no evidence of rotor issues in brake pedel. i have changed all shocks new tires new wheels. what the problem and whats the fix?

 

sorry 200k miles

 

jack the front up and grab the tires at the top and bottom and check for any loose play. could be the front wheel/hub assy bearings going bad.
