You say the differential lock does not work? From the link above, it is a manual shifted lock. If you work the external lever, will the axle lock??? Your's has a vacuum cylinder to work the lever?
The solenid turns the vacuum cylinder on and off, does the vacuum cylinder work? See link above.
Is cylinder adjustment correct? See link above.
I see question is still open, did you see my response?
