After the bearing replacement I had a real rattle-your-teeth vibration at 55+. Dealer first said all the tires were out of round (OOR), then said they weren't.
Finally took the car to my local tire dealer. He knew he was just checking it not selling me a set of tires. Found a flat spot on the left rear (the wheel with the bad, changed bearing) and it was way OOR. Also, the right front was headed in that direction. Looks like either the bad bearing caused the OOR or the OOR caused the bad bearing!
We'll see what the dealer says.
