can someone give me a ballpark figure?

 

It depends on 2wheel or 4wheel. 50 bucks for 2 and about 100 for 4 with a lifetime warranty hopefully.

 

Depends on if you have added a camber kit and want the camber adjusted, as well. Otherwise $25-30 for 2-wheel and $50-$60 for 4-wheel is average for a quality shop to check the readings, adjust toe-in as necessary, and road test the car to check their work.
