I have a 91 civic DX with about 90k on it. Lately (now that its colder) I have been getting a buzzing noise from somwhere behind the guages at speeds greater that 30. So I took off the cover to get behind the guages and drove around. It seems like the speedo cable has a ton of vibration in it.

Any ideas? Is there a way to lube it or should I replace the sucker?

Thanks
