ABS, STABILITRAK LIGHTS ON 2020 YUKON SLT

[Bigell]

…On my 2020 Yukon SLT- here’s the issue::::The Stabilitrak and Abs lights came on last week, this was after a couple of really bad snow days. Code reader kicked out 4 codes that indicated the right front wheel speed sensor had a problem.
U0422-71, C0040-05, 08, 3A. I changed the sensor, cleaned out the area and installed GM sensor. Drove the car around the block but the same lights were still active, even after I cleared the codes.I plan on taking it apart and cleaning the area with brake cleaner thoroughly. Am I headed in the right direction?? Any help is welcome, smart comments are welcome also.

if changing the sensor did not fix the problem then it could be or most likely is the hub.
you could verify with a scanner and looking at all 4 sensor data at the same time
otherwise the hub may be making noise or may have other signs of wear such as being loose
you can check it by jacking up the wheel so it is off the ground, grab the wheel at 12 & 6 and see if it has any play, also check at 3 & 9 but there will be some play because of the steering. also spin the wheel and listen for ticking noise or grinding sound.

Generally when a speed sensor fails, the hub is generally trash as well. I know it used to be common knowledge that if one of the hub sensors is bad, the hub generally needs to be replaced
