Having some vss problems need help

So I just acquired another 7.3 in hopes of fixing it up so I can sell my cummins, because I regret selling my last 7.3. Anyway this one has all the symptoms of a bad vss... O/d light flashing, abs light on, speedo not working, rough shifting etc.

So today I replaced the vss in the rear diff, old one was cracked, so I figured this had to be the issue. Once I replaced the sensor I started the truck and the abs light was off, until I accelerated then everything came back on, so I just parked it. Any idea why a new sensor would "fix" this issue only temporarily??? I'm stumped

Pull the new one and see if has been damaged by the tone ring.

Think the metal shavings could be effecting the sensor?
