I originally posted this on the SuperDuty forum...without much response. Hoping for more here.

I've seen this topic come up a few times but I have not found the answer that is applicable to my situation.

I'm the original owner. I have had some sort of alignment issue since new. My current symptoms are:

- wearing of outer passenger front tire.
- drift to the right. Have to hold the wheel at 11 o'clock to keep straight.

Maintenance performed:
- new upper/lower ball joints, tie rods, drag link 25K ago. (motorcraft parts)

I bought lifetime alignment from Firestone. I went in over the weekend. They performed alignment check but found it within spec. They also looked for an worn components. None found. Both front tire were down a few lbs.(65Psi). I rotate and re-balance every 4K. Tires have about 6K on them (Michelin LTX M/S 2). I also have dual steering stabilizers installed. Any recommendations of where to look or adjust that could be causing this continuing issue? Thanks in advance for y'alls help.

Could this be a sticking or dragging brake caliper issue? Perhaps the flexible line on that side is beginning to collapse?

 

thanks...ill take a look at that...

 

You might need to adjust the left caster down a little for your pull.
