Over the course of about half a dozen turns at HHR today, my steering progressively locked up to the point where I can't move it. At all. Like it's welded. Unfortunately had to be hauled off which was a trick given that I can't make the car go in any direction other than about 10 degrees to the left.

Doesn't seem that a steering rack should go bad in 5500 track miles (what's on the odo). Or maybe that's not unreasonable.

Aside from replacing the rack, thoughts on other troubleshooting? Google has been little help.
