WHEEL LUGS
I
WARNING: Wheel lug nuts must be applied and maintained at the proper
torque levels to prevent loose wheels, broken studs, and possible
separation of the wheel(s) from your trailer. The lug nuts on the wheels of
your Jayco trailer must be maintained according to the torque values
listed in the chart contained in this section. Over torquing and under
torquing wheels are both dangerous.
I
WARNING: Towing, especially during the break-in period, can cause
wheel lug nuts to loosen. Failure to maintain proper torque of the wheel
lug nuts could lead to separation of the tire and wheel while driving,
possibly resulting in property damage or personal injury.
After your first trip, check the wheel lugs periodically for safety. Check the wheel lugs after
winter storage, before starting a trip or following extensive braking. All lug nuts are
13/16”, except on the eight (8) lug wheel, which are 7/8”. Be sure to use only lug nuts
matched to the cone angle of your wheel (usually 60° or 90°). The proper procedure and
sequence for attaching the wheels and torquing lug nuts is as follows.
1. Start all nuts by hand to avoid cross threading.
2. Tighten the nuts in the sequence shown in Fig. 4.
3. Tighten the lug nuts equally in stages as indicated in the chart.
4. Torque the wheel lug nuts before the first road use and after each wheel removal.
Check and re-torque after the first 10, 25 and 50 miles (16, 40 and 80 kilometers).
Thereafter, check and maintain the torque as defined in this section.
Wheel Torque Requirements
Wheel Size 1st Stage 2nd Stage 3rd Stage
12-inch 20-25 35-40 50-75
13-inch 20-25 35-40 50-75
14-inch 20-25 50-60 90-120
15-inch 20-25 50-60 90-120
16-inch 20-25 50-60 90-120
Digital or dial torque wrenches are the best to assure the proper amount of torque is being applied. Also
review the axle manufacturer’s operation and service manual supplied with your trailer or contact your
independent, authorized dealer for further assistance.
