I thought it was the speedo so I grabbed a known working speedo from my stash and it still made the noise but not as loud. Next I removed the Speedo cable from the truck and removed the cable to clean and grease it. When I reinstalled it the noise was still there but not as bad.
I am leaning towards the speedo gear housing being the problem but visually the housing and gear look fine. It seals so no leaks.
Has anyone had a similar problem like this before.
I want to get this issue resolved because my 17 year old nephew has been asking me all winter to let him use my truck for his prom. Well I agreed and his prom is this coming Saturday.

Try another cleaning-and-greasing. Sometimes heavier(or lighter) grease than that
designed for it will work better. Is cable long enough to try a slight re-route? Try using nylon tie straps to shorten/reposition the sharper bends. HTH,
