Steering Stiffness

[Jeffatpm]

My x is being a bit odd lately. When I turn the wheel all the way to the left, about midway it gets stiff. Stiff enought I have to push to turn the wheel all the way.
It does both turning left and returning to center. When I make a corner instead of the wheel tracking back to center, I have to pull the wheel back to center.

I've changed the steering fluid out by sucking out the fluid in the resevoir and replacing.
I did notice the cv axle boot is torn on the drivers side wheel. Has anyone seen a dirty cv joint cause a problem like this, or had a similar experience.
Thanks
Kevin
