Speedo Gauge Help

[Canadian1968]

My speedo was jumping all over the place at low speeds it would steady out a bit at higher speeds but there was still some wobble of about 5 - 10 mph.

I bought a brand new Mopar replacement cable , installed and took it for a drive. It still jumps like crazy at low speeds and will steady out a bit btter at about 50-60 MPH ( according to the gauge) . There is a clicking sound as well when driving.

I am waiting for some decals to redo all my gauges, so i will be pulling out the cluster and completely disassemble it. What can I look for in the speedo? I read the cluster resto thread and it mentioned something about the brushes being shot , the gauge is pretty much garbage??? It doesn't explain at all how to check for this.

Thanks???

I could be wrong but it still sounds like the cable is binding a little or the gear . Did you make sure the cable is well lubricates in the casing ? or check out the gear and condition of it in the tranny ?

X2 pull the cable and lube it with some white lithium grease

I pulled the gauge out. When i turn it manually I notice that it binds at a specific point each rotation. Also the gears that connect to the odometer are not moving at all , and I can't even turn them by hand. I think this is what is binding up the gauge.

I can't seem to remove the two gears that connect the odometer. Metal part part of the housing stops me from removing one of the gears, and the other is held in place by at tab that goes threw the gauge housing. I dont' see how I can remove it with out breaking off the tab and since I can't remove the other gear I am kinda SOL .

Maybe someone can help??

I'm a litle late to this post .... but you might want to give APT Instrumants a call. They specialize in rebuilding these speedos, and do a good job. They fixed mine, and it works great!! Here is their web address for reference:
