The speedometer on my '82 FJ40 started acting very erratic, jumping up to 80+ mph while only going about 40. It is not the plastic gear in the transfer case or cable. I moved the cluster to my '80 FJ40 and it did the same thing. I took it apart and everything looks and seems to work as it should but the part where the cable goes in feels a little gummed up when spinning it. I thought that I would just clean all gears, re-grease, and put it back together to see if that will solve the problem. However, I can't figure out how to remove the gear with the "bell" from the housing. Anyone know how to remove that piece? Also, any ideas on what the problem with the high indicated speeds would be? Thanks!
