A Hydraulic Jack and Jack Stands are customer supplied.
1. See Page 52, Roadside Emergency.
2. Block the wheels on the opposite side from the tire you wish to change. This will prevent accidental movement.
3. Loosen the wheel lugs BEFORE raising the RV.
4. Place a Hydraulic Jack on the frame close to the spring hanger. Raise the trailer until the tire clears the ground
NEVER attempt to use a stabilizer jack to lift the RV.
5. Set up a Jack Stand under the frame just to the rear of the tire being changed, then change your tire.
6. Follow the Wheel Nut Torque and Wheel Installation instructions provided on the Next Page.
Wheel Nut Torque
Torque is the amount of rotating force applied to a fastener, such as a lug nut. The axle and wheel assemblies of your
RV are designed differently than those on your car. The overall size, weight and center of gravity subject the wheels
to pressures unique to trailering. During normal cornering, the tires and wheels experience a considerable amount of
stress called side-load. Therefore, the lug nuts on your RV frequently require torque maintenance.
•
ALWAYS use a properly calibrated torque wrench to confirm proper torque.
•
ALWAYS check lug nut torque on each wheel before departure, regardless of how short the trip may be.
•
DO NOT allow under-torque or over-torque on any wheel.
•
Tighten the lugs in the correct order for your RV's lug pattern shown in the diagram. (Right)
Find your RV's wheel size on the table (Below). Tightening the lugs should be done in three stages. Determine the
correct torque for each stage, and use the torque sequence shown.
