Tone Ring

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.

Toe Ring?

What the heck is, are, tone rings?
