Or the E-clip on the link-rod went MIA.
There is a gov. pressure take-off port on the extension housing just below the speed-o housing.Pressure varies between 0 and 90psi, depending on vehicle speed, and differential gear ratios.Very generally, the psi should be near zero at standstill, rising smoothly about 1psi per 1 mph. So about 50 psi at 50 mph. This number should also decrease smoothly back to zero at 0mph.
