ok after driving on the highway for 30 miles when i get off sometimes the steering gets very stiff and the brakes feel like they want to lock up, but then they suddenly free up and everything is fine. So im guessing their is an issue with the power steering but where do i start to fix it????

When I posted I didn't notice your truck was a 6.5.

So, I don't think my post is of much use to you.

wouldn't it work the same though?
