The procedure is in the manual, but don't overdue it or you can cause binding and accelerated wear in the steering box.

Make sure to at least tip the technician $20 if you do this. They make so little doing a full alignment job, if you arn't going to have them do the work it really puts a dent in their paycheck to only do free inspections. Plus if you come back afterwards to get the new parts lined up they will remember you and treat you better.
