Here is a link to a PDF from the NHTSA from Ford about the 2020 F-53 Motorhome Chassis - Bent Or Damaged Rear Axle Tone Ring(s) that might be of help.
I'm also going to move this thread to the Class A forum as the question fits there better then Tech Issues.

Thanks for the information. I have a 2020 F53 chassis on my 2021 Fleetwood Flair with this exact problem. Hard to diagnose if you don't know about the Tone Ring. I replaced the Wheel Speed Sensor first. Not the problem. Tone Ring!....never even knew it existed. Defective Tone Ring shuts down ABS, Traction Control, Hill Assist, and Cruise Control at the same time.
