When I pull out on dry pavement my traction control takes over causing the vehicle to not accelerate. Even with the traction control turned off, the abs activates more frequently than normal. I read in one forum that the problem was possibly a bad wheel bearing. I jacked up the front end and both front wheel bearings seem to be okay, no movement. When I checked the rear I did detect some movement. Is this normal? Does anybody have any ideas what the problem could be?
