International Roadcheck: Wheel Ends
Event Dates: May 17-19, 2022
During the yearly International Roadcheck event, the CVSA focuses on a specific aspect of a roadside inspection. During 2022 Roadcheck, the focus will be on wheel ends.
Wheel end components support the heavy loads carried by commercial motor vehicles, maintain stability and control, and are critical for braking. Violations involving wheel end components historically account for about one quarter of the vehicle out-of-service violations discovered during International Roadcheck.
During inspection of wheel ends, inspectors will:
- Check for cracks or unseated locking rings, studs or clamps.
- Check for bent, cracked or broken rims on the inside and outside wheel rims.
- Check for loose, broken, missing or damaged wheel fasteners and elongated stud holes.
- Check spoke wheels for cracks across spokes and in the web area or slippage in the clamp areas.
- Check the hub for lubricant leaks, missing caps or plugs.
- Check the inner wheel seal for leaks.
- Check the tire and valve stem for leaks.
- Check for proper inflation, cuts and bulges on all tires, including the inside tire on a dual set.
- Check for regrooved tires on steering axle.
- Check tread wear and measure major tread groove depth.
- Inspect the sidewall for improper repairs, such as tire plugs.
- Check for exposed fabric or cord.
- Check for tire contact with any part of the vehicle.
- Check for markings on the tire that would exclude its use on a steering axle.
- Check for debris between the tires.
- Check for tires touching one another or any part of the vehicle.
