I have a 2005 5.4 f150 and recently when I make a corner my truck will shutter and shake. It is only when the steering wheel is half turned that it does this and if I turn it past that point it will stop but for the majority of a turn it shakes and makes a noise. any ideas on what it could be?

 

If the shudder is in the steering wheel it could be the power steering pump. If it feels like it's in the seat of your pants, it could be the limited slip clutches in the rear axle of the truck. There's a special additive you put in the rear end.
