It is important to maintain proper torque to provide safe and
secure attachment of the wheel to the hub/drum. Be sure to
use wheel nuts that are compatible with the coin of the wheel.
Improperly torqued wheel nuts can cause the wheel to separate
from the wheel mounting surface during operation. This could
result in property damage, serious injury, or loss of life.

7. AXLES
The axle beam (tube) itself requires no maintenance unless it has
become bent, causing unusual tire wear, camber or toe in/out. If this occurs
the beam needs to be replaced or realigned to prevent continuous tire
wear. Special alignment equipment is required to correct this condition.
A. Bearings
Wheel bearings are enclosed with a dust cap on outside and a seal
on the inside, protecting bearings. Beginning in year 2004 a new method
is being used called “Ultralube®”, containing a grease zerk behind a
black rubber cover or dust cover, allowing the owners to place grease
into bearing with a grease gun.
1. Remove the rubber plug from grease cap
2. Insert grease gun on the grease zerk.
3. Place three to five shots of grease in each
zerk every 3000 to 5000 miles. Over
greasing will put grease on brake shoes.
4. Reinstall rubber plug.
The Ultrulube® system DOES NOT remove the need to repack
bearings as listed below. We recommend repacking once each year
(every other year maximum) or 6,000 miles. Also inspect bearings and
hubs for any damaged components when you have it apart.
All wheel bearings in your coach are pre-greased at the point of
assembly. At six months or 6000 miles of use, inspect the bearings for
lubrication and wear.
Wheel bearings require visual inspection, cleaning, repacking, and
inspecting the overall condition.
