speedometer still bouncing

so i changed the speedo cable and speed sensor in my 93 ranger, but still getting the speedometer bounce. what could be next? the speedo housing in the cluster? lubed the inner cable, made sure nothing is kinked or sharp bends. Put in a new vehicle speed sensor while i was at it just bcuz. cruise control does not hold a steady speed either but i think the 2 are not related. I'm leaning towards the cruise control servo as to why it does not hold a steady speed. Most of the time once i get to around sixty i'm basically driving by ear bcuz the speedo bounces from 60down to 55 and back up.

My guess is that your speedometer head is in need of lubrication, causing the speedo cable to load up and then unload repeatedly.

I put in a new speedo drive gear. All back together, no leaks, no bouncing needle, cruise control works now and holds a steady speed. so nice to have the cruise back. I think i'll send back the servo as its not needed now. only negative is the speed is off. speedo says 60, gps says 64. oh well. I really think the problem was the yoke nut was loose. The old gear looked as good as the new one. There was a lot of play between the yoke and the transfer case, the nut was pretty loose. all tight now and no play.
