U.S Federal law mandates that the mileage on a replacement speedometer must match the mileage on the removed speedometer. To replace the speedometer, start by disconnecting the battery negative cable. Then, remove the instrument cluster and, if applicable, the clock reset knob and retainer. Take out the screws holding the mask and lens to the backplate and remove them. Disconnect the speedometer cable at the back of the speedometer. After removing the attaching screws, take out the speedometer from the cluster. To reinstall, place the speedometer in the backplate and secure it with the retaining screws. Apply silicone damping grease to the speedometer drive hole. Put the mask and lens back in position and secure them with the attaching screws. If applicable, reinstall the clock reset knob and retainer. Finally, install the instrument cluster and reconnect the battery negative cable.

To remove and install the instrument cluster in a vehicle, start by disconnecting the battery negative cable. Then, remove the steering column shroud and the cluster trim cover. Next, detach the PRND21 cable from the shift cane and remove the plastic clamp from around the steering column. After that, remove the screws holding the instrument cluster to the instrument panel and disconnect the speedometer cable. Disconnect the cluster electrical plug from the printed circuit and lift the cluster away from the dash panel. When installing, apply silicone damping grease in the speedometer head drive hole. Connect the electrical feed plug to the printed circuit and push the cable onto the speedometer with a twisting motion. Place the cluster back in position on the instrument panel and secure it with the retaining screws. Install the plastic PRND21 cable clamp around the steering column, ensuring the clamp locater pin is engaged in the slot. Adjust the cable clamp until the indicator pointer is centered on "D" while the transmission selector is in the "Drive" position. Finally, tighten the clamp screw and reconnect the battery negative cable.
