Judging from some of the threads I came across in searching I'm leaning towards my issue being a problem with the actual speedometer, I just wanted a second opinion before I drop 30$-50$ on one.
Sometimes my speedometer is fine, sometimes it isn't, lately it's more wrong than right. You'll be cruising about 20-30 miles, often it'll be fine, then you go 40-ish (I suppose) and it does weird stuff, like peg itself past 60 mph. Then it wont work appropriately again till you stop, sometimes that doesn't even correct the problem.
I went ahead and checked the speedometer cable first, it appears to be in good shape, and actually appears to be relatively new, its a barcode on it thats still white, and the sheathing is bright clean plastic, and when you turn one end, it turns the other.
Next I checked the speedometer (gear) adapter, I took it off the transfer case, and aside from being leaky from a bad seal from someone overtightening it, it appears to be moving correctly, I put a similar seal on it to stop the leaking, greased it, and reinstalled it.
I guess by the process of elimination and judging from other threads that leaves the speedometer itself as the culprit. I don't really know how to test it, other than driving the truck and observing whether it works or not, which I do all the time.
Anyone have any other ideas? Anything I missed beyond those parts? Should I go ahead and buy a new speedometer? Could it still be the cable despite outward appearances and the fact the speedometer is receiving rotation?
