What causes differential bearing failure on the PK5/PK6 gearbox?

The PK5 and PK6 gearboxes are prone to water ingress through a worn breather or corroded casing. Water contamination destroys the grease in the taper roller bearings, causing rapid wear, noise and play. This leads to the characteristic whining or rumbling noise from the differential area, and ultimately to bearing collapse if left unaddressed.

What are the symptoms of a worn differential bearing on the PK gearbox?

Symptoms include a droning or whining noise from the gearbox that changes with speed (not engine speed), vibration through the gearlever, and in advanced cases clunking or knocking from the differential area. The noise is often worse on overrun or during cornering.
