Master Tech Dave Welch shows us how to diagnose and repair problems with your Speedometer. In this case, our trucks speedo was making noise AND bouncing around when driving.

As soon as I reach 35 mph my Speedo goes crazy and makes a weird grinding type of noise
The speedometer went from working, to showing really low, to being stuck at 30mph or so 24/7, I'm guessing that's a gauge issue not a cable issue?
Thanks for the video! I’ve got an 82’ chevy 20 with no speedometer movement at all.
This video has helped a lot just by showing me the system, even if it’s not the exact same issue I’m having!!
For me, and anyone else who might be wondering, when I look at buying replacement cables sometimes they’re labeled as “lower” or “upper” and sometimes they have different lengths.
To know what to buy, is it is simple as removing said cable and just measuring it for length? Or
Is there some other info that idk!
Thanks again!
My speedometer cable is connected behind the speedometer cluster with duct tape. I noticed the cable end that connects behind cluster is cut in order to fit over the end. That’s why it was taped. I seen online speedometer cables with two different ends. I’m not sure which one I will need? My gauge cluster does not have a Clip like yours? What should I do?
Mine is out of calibration..is it still the same way to fix it?
One problem I have been having is a dinging sound like a door bell around 100KM/H in my 1985 s15, also have my speedo going crazy after 110 KM/H it basically goes to 6 O’clock. I will try this out and see if it fixes everything. I also get a low kinda rubber and rubber sound like my cv boot is rubbing, at low speeds.
I will give this a try and see if it fixes my issue
My speedo cable wouldn't turn so I removed it and there was obvious damage, either thermal or mechanical, so I replaced it. The new one seems to be too long so I think I may not have routed it correctly. From the engine compartment, does it route inside or outside the frame rail initially? Thanks.
So my speedometer only works when going around tight turns. Even then it only works for a few seconds after I straighten out. I've tight to tighten it up at the transmission but that hasn't changed anything. It did happen to start working when I hit 90mph though. It's still working so far but its a bit shakey at slower speeds. Any ideas as to why that happens?
Any advice on how to access the instrument cluster?
How to fix a floppy gas petal
Thanks I just learned something I didn't know I could do
Thought I needed a new cable
Tried the drill and speedometer worked. Reassembled evening but speedometer still didn't work. Any idea of what it could be?
I tried pulling out my cable from the top with needle nose pliers by it seems tight, am I just not pulling hard enough?
Can you make a video of the different gauges, and styles , and circuit boards , and wiring harness original stuff
