Probably not the case but another issue that can cause this is an alignment where the "thrust angle" is out of whack. Earlier this year when I replaced a good portion of my suspension front and rear, I had this happen. After I got it aligned the problem went away.
Also is your steering wheel centered when the car is going straight? If it's off by too much that could be the problem.
