Lubrication

Wheel Bearings

The Bigfoot is available with or without front brakes.
There are two different lube procedures depending on
whether your vehicle has front brakes.
Refer to the lubrication chart for grease specification.
Front Axle without Brakes
There is a grease fitting located on the inside face of
the hub.
1: Clean the exterior of the grease fitting so that
debris is not injected into the bearings.
2: Remove the bearing cap.
3: Inject grease until a small amount is extruded
through the outer bearing.
4: Reinstall the bearing cap.
5: Using a tool similar to the one shown below, slide
it under the seal so that it is between the seal
lip and the spindle. This will allow grease to slip
through the seal so that the pressure does not
pop the seal out of the hub.
6: Inject grease until a small amount is extruded
through the lip around the tool.
7: Wipe off any excess grease.
Front Axle with Brakes
1: Remove the hub from the spindle. Refer to the
front axle section for information on how to remove and install the hub.
2: Remove the grease seal and discard.
3: Remove and thoroughly clean the inner and outer bearings.
4: Thoroughly clean the inside of the hub and bearing cap.
5: Pack the inner and outer bearing with grease.
6: Insert the inner bearing into the hub and install a new grease seal.
7: Reinstall the hub on the spindle.

WARNING
Incorrect lubrication of the front wheel bearings may
result in contamination of the brake pads and rotor.
This will significantly increase stopping distance and
may result in severe bodily injury and/or property
damage.
If the brake pads have been contaminated they
should be replaced.
