finger pointing

[RLCollins]

Do you remember as a child, that one person in your life that pointed a wobbly index finger at you when you were bad? Well; it reminds me of what my speedometer is doing. It pulses between two and three miles an hour at any given speed :hmm:

The speedometer has not been used in approximately two years. Does the speedometer cable need to be lubricated? What would you use? OR am I looking at this wrong? What would you do? :hmm:

I would start by tracing it back to the transfer case... Looks for pinches, hard turns, or anything that would make it bind.

Thanks Rob I will try it :yes:

Disconnect it at both ends and throw some grease on it. That fixed it for me.

It could be a kink or tight bend, or lack of lube, or both. For lube, I think probably something like the white lithium grease that comes in the spray cans (such as we use on the door hinges) might be a good choice. I just checked the FSM and I can't find any mention of a lubricant for the speedometer cable, so you're kind of on your own.

Might try somthing like this it's for boat steering cables.

IIRC, we used dry graphite back in the old days.

[RLCollins]

yep - I hear you Godblazer, I have to agree with you, Eagle thanks for looking it up in the FSM, Gary is thinking along the same lines, and so is KYMJ. And The results are in - there is a four out of five vote for lubricant. :yes: So I will try it, and also check the cable for kinks. It's great to see people of the same page. :bowdown:

:agree: Yes, graphite's the best because it doesn't gum up. :cheers:

Had the same problem with a '38 Buick.Greasing the cable helped but not entirely. Finally removed cable and housing from car. Cleaned thoroughly, Cleaning solvent and .22cal bore brush thru housing,good soaking and wipe down of cable. Make dern sure ya get all the solvent out B4 reassembling.Reassembled using graphite and white lube mixture. Worked great for a week. Then the speedometer head quit. Sometimes I feel like going into another racket. :mad:

another thing that causes jumpy speedos is a mis-clocked speedometer cable adapter on the transfercase.

 

it's offset to allow for differences in diameter in different speedo gears due to the variety of teeth needed for any given tire to gear ratio....so it must be clocked right to get proper contact on the worm gear in the transfercase/tailshaft housing.
