Traction control comes on randomly on right turns

I changed:
- Rear axle bearings and seals
- Rear LSD differential fluid (used 75w-90 synthetic)
- Front right wheel hub assembly (with sensor)
- Rotors and brakes (compressed calipers and bleed out entire system of air)

When I make right turns at higher speeds, the traction control (stabiltrack) goes on randomly. No ABS warning light comes on, only the stabiltrak.

No noises at wheel bearings. No play at wheels. Everything is firm.

Could it be:

- Lack of rear LSD differential GM oil additive?
- Defective new front ABS sensor?
- Some air left in ABS module?
- Some other issue?

Thank you for any help!
