Problem is with my 97 but I'm sure you guys will know based on most trucks. At low RPMs(2000 and below) the steering gets real tight. Like I will turn a little to the left and it feels like the tire hits a block then suddenlly someone removes the block and it turns fine. I'm thinking power steering pump or just bad steering components since its an IFS and theres a lot to go wrong under there. I'm gonna regrease steering stuff today and see if that helps.
