Frequently Asked Questions
Q: What does the SU S730-XL-A load wheel assembly include?
A: The SU S730-XL-A is a complete pre-assembled wheel unit that includes the SU S730-XL wheel core, sealed bearings, retaining rings, and axle spacers. It arrives as a plug-and-play replacement requiring only hub removal and installation. Do not disassemble the unit; if bearings fail, replace the entire assembly.
Q: Can I install the SU S730-XL-A assembly myself or do I need a technician?
A: Installation is straightforward if you have a wheel puller and basic hand tools. Unbolt the hub from the axle, align the SU S730-XL-A assembly bore with the axle, and tap or press into place. Reinstall fasteners to torque specification of 45-65 foot-pounds. No special alignment or balancing is required. If uncertain, have a field technician perform the swap.
Q: How does the SU S730-XL-A assembly compare to buying the wheel and bearings separately?
A: The SU S730-XL-A assembly offers cost savings of 15-20 percent versus purchasing components separately because bearings are pre-fitted and pre-lubricated at the factory. Installation time is reduced by 50 percent because no bearing adjustment or seal installation is needed. Warranty coverage includes both wheel and bearing failure for 12 months.
Q: What is the expected service life of the SU S730-XL-A assembly?
A: The sealed bearing cartridge in the SU S730-XL-A assembly provides 24-30 months of service life under normal warehouse conditions. Outdoor use or wet environments reduce bearing life to 12-18 months. If bearing noise develops or wheel locks up, replace the entire assembly; bearing cartridges cannot be serviced. Tire wear typically exhausts before bearings fail.
Q: Is the SU S730-XL-A assembly equivalent to competitor assemblies?
A: The SU S730-XL-A assembly cross-references to Yale 582031637A and Crown 101893-701A when wheel and bearing core dimensions match your truck hub. Do not substitute assemblies with different bore diameters or hub widths; this will cause vibration and premature bearing failure. Verify OEM part compatibility before ordering.
Q: What maintenance does the SU S730-XL-A assembly require?
A: The SU S730-XL-A assembly requires minimal maintenance because bearings are sealed. Check monthly that the assembly spins freely with no grinding or wobbling. Inspect the wheel tread for flat spots and debris. Do not attempt to re-lubricate sealed bearings; over-lubrication causes seal failure and water ingress. Replace the unit if bearing noise develops.
