PART 8: MAINTENANCE AND SERVICE
PB1319 (CAT. NO. 5296 ) —125— 22-01691 (R02/02)
Wheel Bearing Lubrication
Oil-lubricated Driven Hubs
Use hypoid oil, A.P.I.-GL-5 SAE 80W-90 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 differential oil level
by adding oil until its surface is even with the bottom of the filler hole (see
page 116
).
Oil-lubricated Nondriven Hubs
Use CD50 synthetic transmission fluid SAE 50W or equivalent. A min-
imum of 9 oz (270 ml) of lubricant is required for proper lubrication of
an LMS™ hub; 10 - 13 oz (295 - 400 ml) is required for a non-LMS
hub, depending on wheel design Allow time for the fluid to seep
through the bearings when initially filling a hub. When properly filled,
the fluid level will lie between the fluid level line and 1/4” above the
line. (Note: Remember to replace vent plug when done.)
Grease-Lubricated Hubs
Repack the hub bearing with clean wheel bearing grease after disas-
sembling, cleaning, and inspecting.
Universal Joint Lubrication
Refer to the Spicer Universal Joints and Driveshafts service manual
and lubrication specifications.
