replace it!

i have also heard that you can lubricate the speedo cable with graphite, but i don't really understand how you can get the core out without ruining the cable.

The core can be pulled and re-lubed if it is in good shape.

You can pull the core either from the tranny or behind the speedo in the dash.

*Recommended method is to unhook both ends
*Pull the core out
*Examine core for any protrusions or kinks. If any are found, replace.
*Otherwise, get some sort of cleaner (W-40) and squirt down the tube from behind speedo until it runs clear.
*Next, take some white lithium grease and spray it into the palm of one of your hands.
*Run the core thru that hand so that it is thoroughly coated.
*Carefully run the core back thru the cable
*Rehook and test it.
*If it still makes noise, the tubing might need replacing or the speedo it self needs some work.

Hope this helps.
