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.
