If the lights are coming on then there's a fault in the ABS/Traction Control System. You'll need to have a shop with the proper equipment so they can address this. I would consider taking it to the shop that replaced the bushing/bearing, as this could be related if it started after that repair.

It could be wiring harness or a hub.
