When grease is pumped into the zerk, it is channeled
to the inner bearing and then flows back to the outer
bearing and eventually back out of the grease cap
hole refer to Figure 5-2. The procedure is as follows:
1. Remove the rubber plug from the end of the
grease cap.
2. With a standard grease gun filled with a qual-
ity wheel bearing grease, place the 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, dis-
placed grease will flow back out of the cap
around the grease gun nozzle.
4. When new, clean grease is observed,
remove the grease gun, wipe off any excess,
and replace the rubber plug in the cap.
