Speedometer does not function properly

My speedometer is not functioning properly. It will work acurately sometimes and other times it will read over or under what it should. Sometimes it ceases to function and sometimes it will climb over 100 mph. Does the instrument cluster need to be replaced or can the speedometer be repaired. If the cluster needs to be replaced can I put a new one in myself? If I do I assume it would need to be recalibrated by the dealer??? Thanks !! Richard Brown

it sounds s if the speedometer sensor has gone or is going out. I would not start with changing the instrument cluster its probably the speed sensor gone bad that is a cheaper fix
