Christmas came early for me - ABS codes

Hey, when crusing on the highway I got this beatiful sight, with cruise control & speedometer not working:




The codes are all related to wheel speed sensors, the question is, should I also replace rear wheel bearings & ABS rings? Weird thing is that when I left the car sitting for one hour, everything was working after that - no lights on the dash.. So I'm honestly not sure if its just ABS sensors or something worse going on. Thanks for any help & advice.

I would just reset the codes though it mght take a few tries. Also if you're traction starts flashing which it might eventually, you'll have to put a washer on the wheel speed sensors. It's because rust forms underneath the reluctor ring that pushes it into the sensor. It can destroy the sensors when this happens.
