I have a 04 F150 FX4, it has a bad vibration and almost throws you off of the road when you hit a bump. It has almost caused me to wreck several times. I need to get it fixed but what i have changed has not worked. It is only the front passenger side. I have replaced lower control arm, tie rod end and realignment. Need some help bad.

 

My 05 I just bought does the same thing. I was going to start with shocks, but haven't had time to put them on yet
