Welcome to Allpar. The speed sensor is driven off the right side front CV axle. The inner axle is machined with a worn gear to drive the plastic speedometer pinion gear. Many times the speed sensor is OK and it is the plastic gear that wears out and skips teeth.
Also check the connector and wiring at the sensor, sometimes the wires will drop down and rub against the rotating axle and ground/short out.
Diagnose first.
