ABS issue 2008 ProStar

[Waterloo]

Going down the road, out of nowhere the warning buzzer goes off in the dash. The Traction Cotrol and ABS idiot lights come on along with the jake brake lighting up and flashing. What is going on? ABS sensor going bad at the tone ring or something worse? I just had a wheel seal replaced on my rear axle, that is the only thing I can think of that may cause this.

Are there any issues with driving the truck like this, say for another week?

Thanks guys!
