Speedometer shows 00's

[Marc Haibeck]

The gear can't go farther forward than the sensor mount. It's now located on the output shaft somewhere between the sensor and the drive shaft slip yolk. If the drive shaft is removed the gear can be removed from the output shaft.

The OE gear has 13 teeth and is grey plastic material. It is retained with a spring clip. In the late '90's there was an aftermarket metal 14 tooth gear that was pressed on. It was used for speedometer correction with a 3.90 axle gear set. Sometimes it was incorrectly used for other ratios.
