Speedometer - Rattle Noise
Bulletin 84-10-23
Date
Sept. '84
Ref.No. 84-302-10
SUBJECT:
RATTLE IN INSTRUMENT CLUSTERS
MODELS AFFECTED:
1984 REGALS AND RIVIERAS
1984 BUICK G AND E CAR INSTRUMENT CLUSTERS
Cause:
The speedometer frame is rubber mounted for noise reduction. This can allow the speedometer dial flange to make intermittent
contact with the plastic retainer, generating a rattling noise. This is especially true when the speedometer neck is exposed to
speedometer cable lateral stress. See illustration.
Field Fix:
In the event a customer comments on a rattle, cut off a piece of rubber gasket (1-3/8" long, 1/2" wide) and attach it with adhesive
to the area shown in the illustration.
Production Fix:
Effective 4/16/84, the addition of a rubber channel gasket to the speedometer dial flange was made. Both procedures will
eliminate the rattle..
