My M1009 speedometer was really jumping around and at time would stop working altogether. I disconnected the speedo cable from where it enters the transmission and attached a drill to the inner square metal cable. While you spin it, check to see if the guage is working. If so, the problem is in the gear assembly. A trip to Autozone was unseccessful in getting a new gear unit. So, I decided to attempt a repair.
Use a 10 mm socket to remove the bolt from the retainer and carefully remove the entire assembly from the transmission. There is an o-ring around the bottom and the fit is quite tight. Pull firmly to remove. Inspect the white or yellow plastic speedometer gear for wear. Mine looked new, with no bent splines or chips. I then looked at the end where the cable attaches. It should also be square. Mine was square but was quite a bit larger than the cable.
Take a small amount of JB Weld and put into this hole just before inserting and connecting the cable. Be very careful to only get it in the center of the opening. This will make a very tight and secure seal with the cable. I left it to dry overnight and awoke to a rock solid speed reading on the guage! Time was less than 30 minutes and the cost pennies!
