Got my AV back after 1st dealer oil change and the steering is looser. Chevy reccommends lubing ball joints each oil change so I don't know if that had anything to do with it. No on center feel now. The steering however is easier to turn know in parking lots. When it was new the steering was very heavy in parking lots but was just right for highway cruising. Does anybody think the steering is overboosted at higer speeds.
