Since I bought the 72 the speedo has always been messed up. It used to not even work but I messed around with the cable a bit and it started workin. Now the problem is the needle bouces till I get up to 30 then its fine and accurate. Ive dumped some cable lube down the cable from the speedo head and it helped a little but didnt stop it. What do yall think would help it?

Sounds like the cable is binding. A new cable might fix it

Hmm ill have to see ifn I can find me one.

Did your cable lube run out the other end.? ( lube the entire cable )
If not force it through with compessed air

Yeah it did go all the way through.

here you go, good people to work with

Already looked there and every other place online and nobody has one for a 4wd f250 with a stick.

take it out and soak it in pb blaster blow it out let it sit then lube it again if that dont fix it then it really need to be replaced. or use ure gps if ya got one and have it display vehicle speed my garmin is acurate to 1 mph

Alright Ill give er a try and see if I can get er to work.

Messed with the cable and its still doin it so I found a whole new cluster on ebay for 30 bucks with all the gauges and no idiot lights. Im gonna swap the heads and see if that works. I also wanted to have some spare gauges just in case mine quit. The bezel is also in alot better condition than mine so thatll get swapped.

No one has any? You sure about that? Uh...see below.

Unless the speedometer cable's housing is crimped, you do not need to buy a complete new cable.

Inside the housing is a woven steel core. Autoparts stores sell a "universal" woven steel core replacement kit.

Buy one a those, cut it to the correct length, install it in the housing.

NOTE: Too little...or no grease at all...will cause the cable to bind up. Too much grease will cause the same thing.

When you replace the woven steel core, put a thin coating of white lithium grease on it.
