2011 super duty psd has new tires, new wheels, no lift or leveling kit and from speeds of 45-50 the front axel seems to bounce and is really annoying. Has 90,000 on it but has been an issue for quite some time now. Also have a friend with the same year and model truck having the same issue. Any suggestions??

 

Bad tires. Put the wheel assembly(tire and rim) on a balance machine and look for the hop. Or it could just be out of balance. A good tire tech will find the heavy spot in both the tire and rim and install them 180* from each other then spin balance. If the tire has a hop no amount of balance will eliminate that.

 

Are you sure it is the front? Many Super Duty models exhibit a rear wheel hop at those speeds. Search for "wheel hop" or "vibration".
