vibration in front end
 

i have an 05 lariat 4x4 5.4 only when i ve been driving for awhile i start getting vibrations on left turns. it feels like im going over a rumble strip but only at a certain point in the turn on three point turns its a little tough but it dosent really vibrate. it only does it when im on the gas. any one have similar troubles. all the front end seems ok like the universals and the shafts.

sounds like u have a cv joint going.
