I have a '92 GT that has had a bouncing speedometer needle for several years, gradually getting worse. I recently purchased a new cable and housing from LMR and installed it over the weekend. Installation was straight forward with no issues. Unfortunately with the new cable the bouncing is as bad or worse. I've read over JRichter's (thanks Joe, again) thread explaining the mechanics of the speedometer system but can't seem to find where the problem is.
The gear at the transmission end of the cable is not worn nor does it show any damage.
With the speed sensor and gear out of the transmission I can feel the inner gear and did not notice any damage or wear to it either.
The cable is securely locked into the speed sensor and the clip is tight. There is no movement where the cable meets the sensor.
From inside the car the cable, when not connected to the back of the speedometer, can be easily taken out of the housing and put back in with no friction. The cable spins freely within the housing until it is seated into the bottom of the housing then stays in place.
The cable snaps into the back of the speedometer cleanly with no issues.
The cable gear and transmission (FRPP Heavy Duty T5), including inner gear, were both changed out 10-15 years ago.
Any advice is welcomed.
