My speedometer in my 48' has always been quiet and all of a sudden it started screaming one day after being parked for the winter in my clean & dry garage. could it be the cable or speedometer or something else ? it seems to only make noise at 60-65 MPH, at lower speeds it seem to be quiet so far. Ive had other issues with cars, but this is a first with a speedometer. I hope someone out there has some knowledge about this issue....

That is the overspeed alarm, telling you your going to get a ticket! In reality, I would suggest you lubricate the speedo cable by disconnecting it from the back of the speedometer, and at the "turtle on the driveshaft. Pull the cable out, clean it, lubricate it. some suggest dry graphite lube, while others use white lithium grease. I'm sure other will respond to your query with ideas. Be careful when reconnecting the cable to the speedo and turtle, as the connectors are fine thread and easy to cross thread. I learned that when I did the cable on my '46 Coupe.

I suggest that the "screaming" you're hearing is internal to the speedometer itself.

Rusty at Speedometer Service in Colorado repaired the speedometer in my '39 p/u. Excellent workmanship, fair prices, fast turn around and reasonable shipping. He also made a cable to connect the speedometer in my '54 Ranch Wagon to an AOD trans. Give him a call. You won't be disappointed. IMO Check him out on the HAMB and Ford Barn for additional positive reviews. https://www.speedoservice.com/ 719-632-3165 ______________ No signature

Good suggestions by MG and bat. One thing you may want to try before sending your speedo out, is when you have it removed, put a couple of drops of 3in1 or clock oil on the perimeter of the shaft that the cable fits into. Then take a piece of 1/4"x4" wood dowel with one end cut square to the size of the speedo cable end, chuck it in a variable speed reversible drill, then making sure the drill is turning in the right rotation, insert the square end into the speedo and run the drill speed up while watching the speed indication to see if you can get to the 60-65 MPH and what the result is. If the noise is gone, lube the cable, reassemble and road test. I always appreciate ideas and suggestion for doing work on my old cars, but I find that testing and troubleshooting before buying new parts or sending something out for rebuild, can save a lot of $$ and time.
