procedure for
maintaining Hub Lubrication
wHeel Hub lubriCation
Your hub/spindle is equipped with a lubrication system. The
bearings can be periodically lubricated without removing the
hubs from the axle. The advantage to this system is that new
grease saturates the inner bearing and outer bearing while
pushing out the old grease, unlike systems that just push new
grease on top of old grease.
1. Remove the rubber plug from the grease (hub) cap.
2. Use a standard grease gun on the grease fitting located at
the end of the spindle, or behind the hub, making sure the
grease gun nozzle is engaged on the fitting tightly.
3. Pump grease into the fitting, while slowly turning the
wheel. Grease will flow out of the hub around the spindle.
4. When the grease appears to be the new clean grease,
remove the grease gun and wipe off any excess grease.
5. Replace the rubber plug in the cap.

A complete inspection and greasing of wheel hubs is required
annually or every 2,000 miles, whichever comes first.

REmOvAL/REmOUnTinG FOR THE wHEEL HUb
Removing the hub for inspection or maintenance should be
done in a safe location away from moving vehicles.
1. Safely elevate and block trailer so that it will not move.
2. Remove the tire/wheel assembly.
3. Remove the grease cap from the hub by prying around the
edge of the cap.
4. Bend the locking tang washer to the “free” position.
5. Remove the spindle nut in a counterclockwise direction and
remove the spindle washer.
6. Remove the hub from the spindle. Be careful not to allow
bearings to fall out of the hub.
7. Clean bearing and cup surfaces, repack with lithium marine
grade grease.
8. Place hub on spindle in reverse order as listed above. Rotate
the hub while tightening the spindle nut to approximately
50 ft lbs. This translates into full hand pressure with a 12”
long set of pliers or 12” long wrench.
9. Loosen the spindle nut. Do not rotate hub.
10. Finger tighten the spindle nut until snug, backing out only
to line up the locking tang washer.
11. Bend the locking tang tab in place.
12. Replace grease/hub cap.
13. Test hub with wheel mounted for excessive play or
tightness, readjust if required.
