Each axle has two integral pivot assemblies which attach the axle to the frame. Each of the four pivot assemblies requires independent lubrication.

There are remote grease fittings for pivot bearing lubrication. The front axle grease fittings are located on the right front frame rail next to the frame level cylinder.

The rear axle remote grease fittings are located beside the right boom lift cylinder.

Wipe dirt and grease from each remote grease fitting.

Remove cap and apply 4 shots of grease to each fitting.

Each axle has two king pins. Each king pin has an upper and a lower grease fitting (total of 4 king pins on each axle).

Apply 4 shots of grease to each fitting.
