Intermittent Stabilitrak/Traction Control message no CEL

[worryle55towmore]

My 2013 Silverado 1500 4WD with 145K miles is acting up. I swapped out a rear wheel bearing, and now I'm getting random Service Stabilitrak and Service Traction Control messages. The check engine light isn't on. Any thoughts on what might be the issue?

Sounds like a wheel speed sensor issue, check the connector and sensor at that rear wheel; cleaning or reseating it usually clears the Stabilitrak and traction warnings.

I agree with @tiger.star, the ABS sensor might not read correctly after you swap a wheel bearing with one that isn't OEM or a good quality aftermarket.
Since you only replaced one, the computer might be getting a weird signal from that corner compared to the others.
Check the wiring carefully for any nicks or pinches. If that looks good, you might have to swap in a better quality bearing or get a scan tool that can read ABS codes and see what's going on with the wheel speed sensors.
It could also be a loose or damaged ABS sensor wire.
