I got a front-end alignment on the xterra last spring as the steering felt funny all winter. I attributed it mostly to the ice and being oversensitive. Anyway, the alignment shop told me my rear thrust angle was off. I soon forgot because the roads were dry and things seemed better.

Anyway, it is winter again and it feels funny again (like I have passive rear-wheel steering in left turns). I dug up the alignment spec sheet and I apparently have a thrust angle of 0.32 degrees (right rear toed out and left rear toed in). Is this fixable with an alignment?

I read on Tirerack.com that this often requires working on the frame. I've never been in an accident and I've never abused the truck. I have 30k miles and I guess I'm looking to know whether this is a huge deal (warranty) or a small issue. Cyclemut did seem to think that 0.22 degrees was fixable in another thread. I just don't see how you adjust it.
