Speedometer needle shaking? Check driveshaft

After months of having the speedometer needle violently shake and bounce during highway speeds, I added grease to the driveshaft fitting, and the needle finally stopped shaking. It’s been months and it’s now a smoother ride and the needle has been steady ever since.

I know the cable requires lube every so often, and I understand these are two separate parts, but if you continue to have this problem, give it a try. I thought I’d pass this along, it worked for me!
