On my 89 cherokee with cruise control, my speedometer needle shakes.
When I bought it earlier this year, the speedo needle has a slight shake and no noise at any speed, but the shake was very small and almost unnoticable.
I went to a junkyard and bought a gauge cluster that looks a hell of a lot better (black and white instead of the blueish one) but after installing it I noticed that the speedometer needle shakes a lot worse at low speeds, and it now ticks behind the speedo.
After searching these forums I found out it could be the speedometer cable, so I took out both the long one from the T-Case to the Cruise Control thingie, and the one from the cluster to the Cruise Control thingie. I couldn't get the actual cable out from the small 6" one, but I was able to get the entire cable out of the long one and I greased it up with white lithium grease. I also noticed that there was a slight crease/bend in the cable right near the firewall that was somewhat hindering the movement of the cable so I took some thick toothepicks and some tape and wrapped them around it to keep it straight and it worked good - no more hinderence.
However after doing all this and making sure it was routed properly and greased up, I reinstalled it and there was absolutely no difference.
Could it be the gauge? I'm hesitant on that because the old speedo did it as well. Could it maybe be the bend still acting up? How sensitive are these cables and how freely should they turn by hand? It turned fairly easily without it connected to the T-Case. I'm kind of out of ideas here without just replacing the speedo cable, which I bet is pricey.
