DODGE TRUCK INSTRUMENT CLUSTER GAUGES SPEEDOMETER

My Speedometer Stoped Working And Also My Abs Light Is Flashing On The Dash? What Could Be The Problem, What Is Needed To Fix?

The Speedo Doesn't Work Right. It Doesn't Start To Move Until About 20 Or 30. All Other Gauges Work Fine

My Speedometer Goes Crazy Anytime I Drive. Its Driving My Miles Up Considerably. I Can Be At A Light And It Says I'm Doing 30 Mph. Thoughts?
