Just a quick note for us northern latitude guys. DO NOT use white lithium grease on the cable. You will have troubles when it gets cold out (cold in MN is different than cold in Tennessee).

When I worked in the shop and had a customer complaining about a jittery or noisy speedo cable we would pull it from behind the speedometer, clean it, then lube it with a graphite based lube that won't freeze up in the winter.
