There are usually a few shops in just about every city that specialize in suspension and alignment. These are the places that a good auto body shop sends cars. Try to find the alignment shop that's been in business for at least 10 years, dong the same work and owned by the same people.
Ask around at places that DON'T do their own alignments, find out who is the best alignment shop in town, then call the shop to find out if they'll do a 4 wheel alignment for you. Then let THEM decide if the front wheels need alignment as well. If you've found a good shop you need to let them do their job.
