One positive of not having installed a stereo(yet) into my vanagon is that I
can hear all the noises.  This morning I noticed a ticking noise that comes
form the speedometer.  Could be the cable too.  My tripometer, odometer AND
speedometer all work fine(the speedo bounces a little bit at speeds below
30.

My request for advice is:
What should I use to lubricate the speedo cable to see if that is the source
of the ticking noise(and maybe that lower speed bounciness)?
I was thinking wd-40(thats what I used to loosen up the heater control
cables on the dash and they work super now) but if it has some dry lubricant
in there I don't want to make a gummy slurry of stuff, anyone with
suggestion on what to go buy at my FLAPS in particular....

thanks,
