Maybe a dumb question but I'll ask anyway. Just had my 15 P90DL in for service and they performed a lot of work on the rear suspension (air) and I'm assuming other things as well. The car now seems to pull to the right. How do I find out if they messed with the front of the car short of contacting service advisor. Isn't this online somewhere? I did not receive any paperwork at SC. 1st time in SC after owning two MS's!
