I got new tires put on the truck and wanted an alignment done. Shop said passenger side ball joints, tie rods and whatever that ball joint off the pitman arm is called are shot. I have an extended warranty with Ford so I took it to them. I told what the tire shop said. After a very long week they said yep, needs ball joints and tie rods along with a rear axle seal and a bunch of other parts. OK, I get it back and they didn't replace the center joint off the pitman arm. The did do an alignment, originally the steering wheel was pointing to the left, now at slow speeds it's straight but on the highway it's pointed to the right. Plus the truck steers like an old Mack truck, slow and heavy. The truck has stock wheels and tires, air pressure is at what Ford wants, 75 front and 65 rear. I decide to find out what's going on down there so I took this video:
2005 F350 Steering in motion - YouTube
It's 12 min long, mix of city and freeway driving. There is play in the pitman arm connection but what you don't see is the steering wheel see sawing translated into movement of the pitman arm.
So, I've going to guess that I have a bad steering box or a box that needs adjusting. That ball joint needs to be replaced and possibly the front U joints too? Dealers getting it back tomorrow, I hope they figure it out.
