I concur. Dealer should include it in the job. You want to be sure that there are no issues down the road with suspension/wheels/bearings that could have been avoided. It is also a good opportunity for you to have alignment check free of charge.
I to agree anytime you get work done on the front suspension or steering system you need to get a wheel alignment. That also goes true if you notice that your car is not steering properly( pulling to one side)
