Speedometer Clicking, Advice Please

Speedometer Clicking, Advice Please
1970 442 with cruise control: My speedometer emits a clicking sound about 50% of the time when I am driving. Neither outside temperature nor the speed I am going seems to make a difference as to when the speedometer clicks. It either clicks or not, upon start-up.
When I first checked the connection at the gauge, there seemed to be plenty of a greasy cloudy-colored lubricant in the connection. So I cleaned it out and re-lubed the connection with distributor cam lubricant with no improvement.
I read in another post here tonight that liquid graphite is the proper lubricant.??
Two other questions:
1) would having the additional (shorter) cruise control speedometer cable have any special effect on how it works or how it should be lubricated?
2) should I lubricate both or all, cable connections?
Any ideas would be appreciated.

Pages 4B-24 and 4B-25 of the 1970 Oldsmobile Chassis Service Manual covers diagnosis of the speedometer system. Ten circumstances are shown which can cause noise. Repair procedures, including lubrication, are shown for each condition.

Thanks and One More Question
Ozzie:
I overlooked that section in the Chassis Service Manual. I did not know you could pull the whole cable out of the shaft to inspect and service it. I was only lubricating the two ends and the coupler at the gauge.
