Wheel Bearing Lubrication
Oil-lubricated Driven Hubs
Use hypoid oil, A.P
.I.-GL-5 SAE 75W-90FE
synthetic gear lubricant or equivalent. A
minimum of 1 quart (921 ml) of oil is
required for proper lubrication of each drive
hub. Add oil through the filler hole in the
hub; if none, add oil through the differential
filler hole.
NOTE
Remember to replace vent plug or
threaded filler plug when done.
Allow time for the oil to seep through the
bearings when initially filling a hub.
Maintain the dif
ferential oil level by adding
oil until its surface is even with the bottom
of the filler hole (see illustration in
Checking Oil Level on page 198).
