01 f150 at 50-55 mph the front end starts shaking violently. Feels like Mike Tyson is beating the crap out of me.
I've replaced inner & outer tie rods (both sides) new shocks. Wheel bearing hubs. New tires. What's next? Any ideas??

 

Jack it up and figure out what is loose before throwing money down the drain.

Could be a misfire too.
