CHEVY SPEEDOMETER NOT WORKING PROPERLY

2002 Chevrolet Tahoe

Electrical problem
2002 Chevy Tahoe 85000 miles

Noticed the speedometer sticking at first, then jumping way beyond actual speed vehicle is going. When we shut engine off the speedometer often sticks at 20-30-50, does not go back to 0. Now the speedometer has gone beyond the 120mph and jumps back and forth.

What can be causing this and how can we fix it--hopefully without having to take truck into the shop.

Thanks
