<VV> EM speedo driven gear squeal

[Eric S. Eberhard]

I have one EM that makes a continual grinding noise both at the 
differential and where the cable connects to the 
speedo.  Unfortunately, this is the ONLY speedo I have ever had on 
any Corvair (and I have had dozens) that is rock-solid.  No wiggle, 
jump, or anything.  I have done as others suggested, removing and 
cleaning and I have tried graphite lube (the best I think for this 
job), WD-40, light grease, bearing grease ... nothing I do stops the 
jumping.  So I just ignore the little noise this one makes, small 
price for a perfectly working setup!  E
