While i was waiting on Fedex (who never showed) I figured I’d tear everything apart. It turns out when I did my ZL1 diff/axle upgrade a piece of the old axle washer broke off and recently worked its way onto the wheel speed sensor’s tone ring (which is built into the wheel bearing).
Turned out to not need any new part for this fix. Cleaned it up and reassembled.
I found this video on uou tube which was helpful. I thought the axle had to come out to get to the wheel bearing, but thankfully not, and it was pretty easy.
