Hello Folks.
1981 Pontiac Parisienne.
Aftermarket ( I think ) cruise control.
Speedo guage needle jumps + fluctuates.
Cleaned + lubed cable from cruise control box to speedo -- no change.
Next will do same for cable to cruise control box from tranny.
If no change, contemplating taking apart cruise control box + lubing +
cleaning inner gears connecting both cables.

Q: Is this possible .. can CC box be disassembled to clean + lube
inner connecting gears?
There are 4 nuts on side cover where cables connect to box.

The speedo itself checks out OK .

Please reply to NG.
