ABS light on 03 Sports Trac

[Westsign]

Hi,
My ABS light just came on yesterday.
I need some input on how to test Wheel Sensor or anything else that would help.
Thanks

Check your tone rings on the back wheels. they like to break. Also have a real good look a the front ones, and check the hubs too, to make sure they aren't loose.

Where you recently on a dyno?
What are the condition of your tires?
Is the wear even?
Same brand/size/model/DOT date on all 4's?
