Suspecting a leak in the left front axle/hub reduction we attended Hans’ shop. After a thorough wash of the area and a road test there was no sign of an oil leak. The left front wheel was removed and the hub reduction and axle area was thoroughly cleaned of oil and excess grease from the king pins. The boot at the transfer case to the front torque tube was inspected and found to have some oil inside. The front diff was also found to be over full. The decision was made to change all the fluids in the hubs, axles and transmission.
Headlights were adjusted and two air-line fitting adapters to allow the installation of quick couplers for air tools or air lines were made. A full brake fluid flush and tire rotation including the spare tire was also undertaken.
40 kilometers later when stopped to refuel, the leak had re-appeared on the left front hub. We returned to the shop. The leak could now be pinpointed to the outer seal on the hub reduction at the front axle.
All seals in the axle and hub reduction were replaced.
Seven hours later we’re back on the road.
