Frequently Asked Questions
Q: What truck models are compatible with the SU S9109-XL-A load wheel assembly?
A: The SU S9109-XL-A is a load wheel assembly variant. Compatibility depends on axle diameter, wheel bore size, and frame clearance. Verify your truck model in the product compatibility chart or contact technical support with your truck serial number. Ordering the wrong assembly will result in installation failure.
Q: Is the SU S9109-XL-A a complete assembly or a wheel only?
A: The SU S9109-XL-A is a load wheel assembly, which means it includes the polyurethane wheel, steel core, bearings, and any integrated mounting hardware as a complete unit. This differs from a wheel-only product. Confirm what components are included before ordering; missing parts will prevent installation.
Q: Can the SU S9109-XL-A be swapped with other Superior load wheel assemblies?
A: The SU S9109-XL-A may not be compatible with all Superior wheel applications due to differences in axle bore, width, or frame mounting. Do not assume interchangeability between different SU S9XXX part numbers. Verify the bore diameter, wheel diameter, and width before substituting.
Q: What maintenance is required for the SU S9109-XL-A assembly?
A: Inspect the SU S9109-XL-A every six months or 500 operating hours for tread wear, polyurethane separation, or bearing noise. If bearings are sealed, no greasing is required. If bearings are unsealed, check the manufacturer documentation for greasing intervals. Replace the entire assembly if the core is cracked or bearings fail.
Q: What is the expected service life of the SU S9109-XL-A?
A: Service life typically ranges from 18 to 36 months depending on load cycle intensity, warehouse conditions, and maintenance. High-cycle operations or wet and chemical environments will reduce lifespan. Track maintenance hours and visual wear to schedule timely replacement before failure occurs.
