Axle systems are installed with hubs and drums that are compatible with
many wheels used in the recreational vehicle industry that have matching
bolt patterns. If the original manufacturer installed equipment is in need of
replacement, the wheel manufacturer should be contacted for proof of com-
patibility prior to replacement and use.
Customers replacing original equipment that has not been tested for compat-
ibility must ensure the replacements are compatible to the hub and drum as-
sembly installed. Such elements of compatibility include, but are not limited
to:
Diameter of the hub-mounting surface.
•
Stud length and diameter.
•
Location and number of studs.
•
Center hold diameter for the wheel.
•
Wheel mounting offset from the rim center.
•
Rated capacity of the wheel.
•
Wheel fastener torque.
•
Wheel nut size and shape.
•
Impact of any added wheel accessories (such as decorative center caps)
•
that could affect proper seating of the wheel to the hub surface.
Lug Nut Torquing
Proper wheel nut torque is very important to safe and dependable towing of
your vehicle. The wheel and axle systems used in travel trailers wheels are
similar, yet different, in many ways to those used on cars and trucks. These
differences are important and require special attention to wheel nut torque
both while the trailer is new and throughout the trailer’s life.
Trailer wheels must carry much higher loads per wheel than passenger car or
truck wheels. Each wheel may carry 1000 pounds and higher. Furthermore,
wheels on tandem axle trailers do not steer, and are subjected to very high
side load stress whenever the trailer makes a tight turn. When you go around
corners, especially slow, tight ones, the wheels on your trailer are subject to
these strong side loads. This tends to flex the wheel and gradually loosen the
wheel nuts. Although the materials and manufacturing methods are maxi-
mized for this kind of service, these extra loads can cause stress, which can
result in flexing and loosening of wheel nuts.
