Get a professional front end inspection done on a proper alignment bench. The key is to find an experienced front end technician. (forget Pep Boys, Sears, Firestone et al).

Call the best body shops in town (you know, the guys that fix the Lexus, MB's and BMW's) and get alignment shop recommendation.

Some will inspect for free, others will charge you $20.

The alignment bench allows sideways movement of the wheels and allows the alignment technician to place jacks at certain points to isolate the suspension components.
