Frequently Asked Questions
Q: What is the difference between SU S9107 and SU S9107-A?
A: SU S9107 is the wheel component only, while SU S9107-A is the complete load wheel assembly that includes the wheel pre-mounted on a bearing hub. If your truck needs only the tread replaced and the hub and bearings are still serviceable, order SU S9107. If you need the entire assembly ready to install, order SU S9107-A.
Q: What is the load rating for SU S9107?
A: Load capacity for SU S9107 depends on the specific truck model and the number of load wheels in the assembly. Verify your truck model and serial number against the application chart in the parts manual. Do not exceed the maximum rated load per wheel as specified by the truck manufacturer.
Q: Can I mix SU S9107 wheels with other manufacturer wheels on the same truck?
A: No. All load wheels on the same truck must have matching diameter, tread width, and material to ensure even load distribution and stable handling. Mixing wheel types will cause uneven wear and can create a tipping hazard. Replace all wheels as a matched set.
Q: How do I diagnose a worn SU S9107 wheel?
A: Look for visible cracks, chunks missing from the tread, flat spots, or tread material separating from the hub. You may also notice the truck pulling to one side, excessive vibration at speed, or audible grinding. Measure tread depth; if it is less than 0.25 inch, replacement is required. Check bearing preload by spinning the wheel by hand; excessive play or grinding noise indicates bearing failure.
Q: What tools do I need to replace SU S9107?
A: You will need a wheel puller or press, an appropriate bearing removal tool (if the bearing must be transferred to the new wheel), a socket set, and lubricating grease if the bearing is greaseable. Consult your truck service manual for the exact hub bore diameter and the bearing specifications before beginning removal.
