Ok I was driving my dads pickup today. I noticed going down the highway at 60 mph and I noticed the steering wheel shook back and fourth ever so slightly. Less than about half an inch from center both ways. The vehicle dosent shake or anything that I can feel. Is this just a normal thing or could there be something possible wrong with it.?? 2005 xlt crew cab 5.5 box 5.4.

Mine does the same. Could be less than perfect wheel balance, uneven tire wear, or any number of things. If it gets worse I'd say go get it checked out.
