Lubricate Wheel HubLubricate Wheel Hub
The axle is equipped with the E-Z Lube® system,
which makes lubrication easy without the need for
removing the hubs from the axle. The grease ttings
are conveniently located on the outside of the axle.
Grease is pumped into the tting where it is channeled
to the inner and outer bearings. (Figure 5-12) The
suspension system should be lubricated every 12
months (or more if used in severe conditions).
NOTE: Only use lithium complex NLGI No. 2 grease
with EP, corrosion and oxidation inhibitors,
a viscosity of 80 minimum, and a dropping
point minimum of 419° (215° C).
DO NOT use a pneumatic-powered
grease gun as those inject grease too fast, which can
force grease past the seal or even dislodge the seal.
Figure 5-12. E-Z Lube® System
To lubricate the suspension system:
1. Remove rubber plug. (Figure 5-12)
2. Place a standard manual grease gun onto the tting,
ensuring the gun nozzle is fully engaged to the
tting.
3. While rotating the hub, pump grease slowly into the
tting. (The old grease will ow back out of the cap
around the grease gun nozzle.)
4. When you see clean grease owing back out,
remove the grease gun, wipe off any excess grease,
and replace rubber plug.
