I have noticed that when I press the brake the truck seems to "drift" a little one way or the other. If you go into a curve and turn to the right it will drift a little to the left and vice versa for the other side. I just replaced the driver's side tie rod end and the 2 big sway bar bushings that mount to the frame. (One on each side). The 1st time I felt it I thought the front end was hydroplanning a little. Scared the piss of me. Lol.
