If you don't notice the pulling then don't worry about it.

Pulling is caused by a variation between the left and right hand camber and castor. pulling can also be cause by tyres as previously mentioned. Rebuilding you steering box will have no effect on any pulling problem.

I wouldn't worry about it unless to are wearing tyres or you notice the pulling. do you have a print out from the wheel alignment or do you know what the toe, camber and castor were set at?
