I had my '05 S60 R rear bearings replaced with new OE from Viva by good friend's mechanic (not volvo dealer). The new ones ride very quiet but I've got a strange hop when the car now corners around the highway at speed. For example going on a highway bend at 65MPH, normally I've never had my anti-skid kick in, now the light is usually coming up and the steering feels nervous. The anti-skid lights flicker as I'm in the curve and its mostly on left hand curve. The tires I'm currently on are winter Dunlop WinterSport 3D M+S. I remember the old Rosso's were bad with the hop but I've never really had the hop issue with the Dunlop. Soon I will be swapping to summer tires, both sets run on 17" pegs.

Any clues I can look for or codes to pull? Maybe a 4C sensor is loose when the bearings were swapped?

Probably just needs an alignment. Also, you may have bent a accelerometer bracket while messing around back there. The wheel bearing has nothing to do with 4C.

Thanks, I'll take a look when I swap winter/summer wheels.

Definitely alignment.
