where did you get the sensor? oem or aftermarket?
pull it and check it.
I have removed new sensors that were manufactured too long and the ring in the rearend destroyed it.
also check wiring especially from the sensor to the frame.

Go to ford for the sensor. I've heard of quite a few parts store ones not working.

I had a 97 f-250 7.3. the samething happened. I replaced the VSS sensor. Two days later the samething happened. I pulled the sensor again and it had metal on the sensor. I pulled the cover of the rear end and washed it out with fuel. I got a speaker magnet and put it in the rear end housing to catch the metal if anymore appeared. Replaced the oil. It is still running fine.
Hope this helps.
