The ABS sensor is also the speed sensor for the speedometer on Rangers from 98 through 2000.
A common problem can be the connection from the interior wiring harness to the rear harness. It is a large 40-pin connector under the driver seat and is accessible from under the truck. Unscrew the center bolt, open it up and look for water or corroded terminals inside. Even if there is none, it is good preventative maintenance to pack this vulnerable connector with dielectric grease, available at Ford dealers and auto parts stores.

I'm not clear on the problem(s). You say that the speedometer is off. Does that mean that it consistantly reads low or high or does it mean that the needle jerks and/or operates erratically? Or is it something else?
Do you have RABS or 4WABS? The ABS light could be due to a failure in some other part of the ABS system that is not related to the speedometer. A Ford dealer has the reader for any ABS trouble codes.

OK, the jerky needle and ABS light sounds like an ABS/VSS problem. Since that sensor has been replaced, it means that you're probably looking at water or corrosion in the connector below the seat. It is a common problem. Not the only possibility but, by far, the most likely.
