Disconnect the negative cable from the battery, then remove the speedometer cable from the transfer case by taking out the retaining bolt and pulling the cable free. Detach the cable from the routing clips in the engine compartment and pull it up to create enough slack for disconnection from the speedometer. Next, remove the instrument cluster screws, pull the cluster out, and disconnect the speedometer cable from the back of the cluster before removing the cable from the vehicle. Before installation, lubricate the speedometer end of the cable with spray-on speedometer cable lubricant available at auto parts stores, and then proceed with installation in the reverse order of removal.
