Maintenance
Standard Bearing Lubrication
Bearings should be lubricated every 12 months or 12,000 miles. If the axles have
been submerged, the bearings should be repacked immediately. Service the bearings
with lithium grease meeting NLGI No. 2 standards. Use this procedure:
1. Place a quantity of grease into the palm of your hand.
2. Press a section of the wide end of the bearing into the outer edge of the grease
pile closest to the thumb, forcing grease into the interior of the bearing.
3. Repeat this while rotating the bearing from roller to roller.
4. Continue this process until you have the entire bearing completely filled with
grease.
5. Before reinstalling the bearing in the hub, apply a light coat of grease on the
bearing cup.
E-Z Lube Bearing Lubrication
If your axles are equipped with the E-Z Lube feature, the bearing can be lubricated
without removing the hubs from the axle. The feature consists of axle spindles that
have been specially drilled and fitted with a grease zerk in their ends. When grease is
pumped into the zerk, it is channeled to the inner bearing and then flows back to the
outer bearings and eventually back out to the grease cap hole. Regrease using this
procedure:
1. Remove the rubber plug from the end of the grease cap.
2. Place a standard grease gun onto the grease zerk located in the end of the
spindle. Make sure the grease gun nozzle is fully engaged on the fitting.
3. Pump grease into the zerk. The old, displaced grease will begin to flow back out
the cap around the grease gun nozzle.
4. When the new, clean grease is observed, remove the grease gun, wipe off any
excess, and replace the rubber plug in the cap.
5. Rotate the hub or drum by hand while adding grease.
