so the truck is wigging.. the abs light and brake light flash at me wile i drive.. when i go to stop the speedo stops at 5mp flickers up to ten then slowly bounces back to 0
replaced the vehical speed sensor in the rear diff.. replaced battory checked connections ect.. please help
thanks nate

 

Double check the connections. I had the positive battery cable that runs from the driver side to passenger side go bad. Mine also would blow up my passenger side battery too though. But I got the same problems you did

 

isnt their brake sensors on the front wheels also mite check them

 

When my car does this (2000 BMW), it's a wheel speed sensor. Grime can get in there and muck things up.
Haven't had this problem on the P/U so far.
