In addition to local auto dealerships, most auto service centers can perform front end alignments on a vehicle. Local mechanic shops are likely to perform this service as well.
Pep Boys, Merchant's Tire & Auto Centers, Firestone and Sears Auto Center all provide front end alignment service. Some of these companies can also provide price quotes on their websites before customers make an appointment. This is a good way to shop around for the best price and to get an idea of the type of warranty and service included. It is good practice to check that the technicians servicing a car are ASE certified, to ensure the job is performed properly.
