Oil filled front hubs

[Mody n Domy]

I have a 2008 Workhorse W-22 with about 38,000 miles. At what point should the oil be changed in the front hubs?

The fluid should be changed every two years. I use
synthetic gear oil 75-90 per freightliners spec.

If you decide to replace the bearing lubricant, the screw cap is intended to be the drain and rotating the wheel to align it at the bottom will achieve the best results. To refill, remove the rubber plug in the center of the seal and add fluid to the bottom of that hole. Wait a while for the oil to level itself and add as needed. Replace the rubber plug. This method will prevent you from over-filling, which WILL create a sticky mess when the oil heats up and starts weeping out around the rubber plug.

FWIW, I have more miles on my 2009 W-24 and have no plans to replace the fluid.

The Workhorse Gas RV Chassis Maintenance Guide says to check the level during tire rotation or once per year and if the fluid is contaminated it must be changed. In the 10 years we had our W22 I never had a reason to change the oil in the front hubs.

The Chassis Maintenance Guide used to be available as a sticky in the Workhorse forum on this site.
