I took my E70 for a checkup due to some speed-dependent noise. Dealer's tech found that it is a bad wheel bearing (at mere 2400 miles). When I picked up the car, they gave me a report where the tech stated that front tires are feathered. I mentioned some doubts about wheel alignment to the service advisor. He told me that the alignment is ok. Now I'm wondering if I can demand a real alignment check done based on the feathering they found? Does it make me eligible for any tire-related "benefits"?
