If you notice wheel wobbling or hear a rattling sound coming from a wheel,
especially at low speeds, a wheel lug nut may have come loose. This prob-
lem is usually caused by improper tightening or by faulty or damaged lug
bolt threads. If you have a reason to believe a lug nut has come loose, safely
stop the vehicle at the side of the road as soon as possible. Put up warning
devices. Remove the lug caps and check the tightness of all the lug nuts.
Tighten all lug nuts to the specified torque, using a torque wrench. If lug stud
threads are damaged or faulty, get professional service help.
Warning
: WHEEL SEPARATION CAN OCCUR
1. On first trip, tighten wheel nuts at start and at 10, 25, and 50 miles.
2. Thereafter, check wheel nuts:
Before each trip.
Following winter storage.
Following excessive braking.
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.
Warning:
Do not mismatch wheels and tires.
