SYMPTOM/CONDITION
Customer concern for grinding or ticking sound in speedometer.
DIAGNOSIS
Road test the car to verify the condition. If vehicle is warm (above 60 degrees) the noise may not be readily apparent..
The sound may be caused by interference between the cable housing connector and the dash panel opening. Use the following procedure to correct the
interference.
REPAIR PROCEDURE
1.
Disconnect the battery ground cable.
2.
Remove the instrument cluster (refer to the 1983 Front Wheel Drive service manual for Removal Procedure (#81-270-3004).
3.
Release the spring clip and push the speedometer cable housing back into the instrument panel housing far enough to gain access to the
speedometer cable opening in the instrument panel. Cover the cable housing to prevent chips from entering the cable.

4.
Using the side of a 1/8" drill bit or small rotary file and an electric drill, enlarge the hole (Figure 1) in the instrument panel to approximately 1" in
diameter. (You are in effect removing the boss molded into the panel.) This will prevent the interference between the speedometer cable housing
and instrument panel.
NOTE:
PAY PARTICULAR ATTENTION NOT TO DAMAGE THE WIRING OR OTHER ELECTRICAL COMPONENTS DURING THE
GRINDING OPERATION. DO NOT TRY TO USE A HOT KNIFE FOR THIS OPERATION.
Use a vacuum cleaner to remove the grinding chips from the instrument panel.
