MAINTENANCE AND LUBRICATION
Figure 4-12: Outboard Mount Hub and Drum
i. Place the drum over the hub and brake shoes
being careful not to damage the threads on the
studs
(See Figure 4-12.) Make sure the drum
seats flat against the hub flange and mates
properly with the hub pilot. There should be no
interference between the brake drum pilot
chamfer and the corner radius on the hub. If
interference exists, the hub will not be able to
function properly.
j. Install inner bearing, cone, and seal.
IMPORTANT
DO NOT MIX NEW CUPS WITH OLD CONES OR NEW
CONES WITH OLD CUPS.
k. If studs are marked “R” or “L”, right hand (R)
hubs should be installed on the curbside of the
vehicle, left hand (L) hubs should be installed on
the driver side.

WARNING
l. Place the hub or wheel over the axle spindle
being careful to align the hub bore with the axle.
Do not damage the seal. Support the hub
assembly until the outer bearing cone and
spindle nut are installed, to avoid damaging the
seal.
m. Install the outer bearing cone and inner spindle
nut, tightening the nut until it is snug against the
outer bearing cone. Remove the hub support
allowing the hub to rest on the bearings.
n. Install and adjust bearings (See “Wheel Bearing
Lubrication and Adjustment” on page 4-21.)
o. Install the hub cap with the proper gasket.
Tighten the cap screws of the hub cap to 15 to 20
ft-lbs. of torque.
p. Remove the filler plug and fill the hub cavity to
the recommended level with a gear type oil.
Failure to use the correct stud on the correct side
may cause loosening of the hub studs during
operation, resulting in loss of a wheel.
