Well, it ended up being the speedometer itself. The shaft that control the needle was broken & the spring came unwound. It was a pain in the butt but we finally got the issue resolved...kind of.
For awhile, the thing was making noise. It finally went away after some driving time. The needle wiggles a bit until you get up to highway speeds.
A new problem has been detected. The speedometer is now off. If it says you're going 45, it is more like 55. If it says you're going 25, it is more like 30. When the other cable was rigged up, it seemed to be steady & not fluctuate.
I wonder if there is some sort of cailbration adjustment on these things???
Also, where all should I lube on these things???
I put some dry graphite around the base of the cable where it goes into the rubber sleeve. Is there a place to lube in the back of the speedo? Perhaps where the cable plugs into the little brass looking thing? Or maybe around the outside diameter of the little brass thing?
Any ideas & help is much appreciated.
THANKS!!!
