Steering wheel sticks when turning right, despite just getting aligned.

[wrestling160]

After wrecking my 4runner on a curb a few months ago, I replaced the rear axle which was bent. I took it to have the alignment checked, and they performed the alignment. The steering wheel sticks when turning right, and there is a slight pull to the right. I'm curious as to what could be wrong with the suspension, considering they were able to perform the alignment. Any insight?

Oh, and there is an occasional grinding noise when the wheel is turned completely to the right...
