'07 Toyota Camry. Noticed in recent months it was drifting to the right - sometimes quite badly depending on the road. The steering wheel would be straight as it did so. It had its service last week, so I told them to check the alignment. They did, and reported the alignment was indeed out. They fixed it and test drove it - all good. However, it now seems worse than before 
Obviously I'll be taking it back. Just wondering what could be going on? Tires maybe? I think they rotated the tires and checked pressure as part of the service. Could it be a sign of something more serious and expensive?
Just want to be prepared for any technical explanations they throw at me, as I know nothing beyond the very basics.
Thanks!
