Removal the instrument cluster from the dashboard
1. Remove the ground cable from the battery.
2. Apply the parking brake, then raise the front of the vehicle and secure it on stands.
3. Working underneath the vehicle, move the speedometer cable to the left of the gearbox. Loosen the retaining ring bolt and remove the speedometer cable from the gearbox. In this case, the speedometer cable can be removed into the vehicle interior when the instrument cluster is removed.
4. Using a piece of strong steel wire with a hook on the end, insert the wire into the gap between the instrument cluster and the instrument panel and, hooking the wire, pull the instrument cluster out of the instrument panel enough to expose the speedometer drive cable (see fig. Removing the instrument cluster from the instrument panel).
