Carefully remove the rotor (or hub) from
the spindle taking care to prevent the
outer bearing from falling out of the hub
assembly. Remove the outer bearing
and set aside. Invert the hub assembly
so the inner seal is visible. Remove the
inner seal and discard. Replace with a
new seal at reassembly. Remove the
inner bearing and set aside.
Wipe each bearing with a clean cloth.
Be careful to remove all excess and
contaminated lubricant. Wipe the
spindle clean with a clean cloth.
Examine all bearing and spindle
surfaces for discoloration or pitting. If
evidence of either, replace all affected
components. In the case of evidence of
water contamination, replace all
bearings and seals immediately.

temperature lithium based NLGI #2
wheel bearing grease. Reassemble in the reverse order of disassembly.
Remember to
install a new seal and a new spindle nut locking device
.
DISC BRAKES
Reinstall the caliper over the rotor and
secure with the stainless mounting
bolts. Apply blue Loctite to the
threads of the slider bolts. Torque to
20 lb. ft. if coarse threads, 35 - 40 lb.
ft. if fine thread.
Install the wheel. While rotating the
wheel, torque the spindle nut to 20 lb.
ft. Loosen ¼ turn and retighten by
hand until snug. Securely fit the
spindle nut locking device.
Torque the wheel lugs to 80
– 95 lb. ft.
Repeat all of the above for each
wheel on your trailer.
IMPORTANT - BLEED YOUR BRAKES
Bleeding the brake hydraulic system at each caliper should be part of
annual trailer maintenance
. Brake fluid absorbs moisture and becomes
ineffective at converting hydraulic pressure to braking action.
It is possible
for the brakes to become ineffective or even lock during operation if the fluid
is not serviced annually.
