Frequently Asked Questions
Q: What is included in the SU S359-A load wheel assembly?
A: The SU S359-A is a complete wheel assembly that includes the load wheel, mounted bearing, snap ring retainer, and hub components. It comes as a pre-assembled unit ready to slide onto the truck axle. This eliminates the need to source individual bearing or snap ring components separately and ensures compatibility of all parts.
Q: Should I order SU S359 or SU S359-A for my truck maintenance?
A: Order SU S359-A if the bearing is damaged, worn, or you want a complete replacement without disassembly risk. Order SU S359-A if your technician is not experienced with bearing installation or you need minimal downtime. Order only the SU S359 wheel if the existing bearing is good and you simply need a new wheel. SU S359-A costs more but saves labor and eliminates bearing compatibility errors.
Q: Can the SU S359-A assembly be partially disassembled and mixed with other wheel components?
A: No. Do not disassemble the SU S359-A into separate components and mix parts with other wheels. The bearing, snap ring, and hub are sized and matched to work as a unit. Swapping components between assemblies will cause misalignment, bearing failure, or snap ring incompatibility. Keep complete assemblies intact.
Q: What is the installation process for the SU S359-A pre-assembled wheel?
A: Support the truck securely on a lift. Remove the snap ring holding the old wheel assembly. Slide the old assembly off the axle. Inspect the axle shaft for damage or corrosion and clean if needed. Apply bearing grease to the axle bore. Slide the new SU S359-A assembly onto the axle, ensuring the snap ring seating groove aligns. Install the snap ring, confirm the wheel spins freely, and test the truck before returning to service.
Q: Do I need to pre-grease or adjust the SU S359-A before installation?
A: The SU S359-A arrives pre-assembled and bearing-ready. Do not disassemble to add grease. Apply a light coat of bearing grease to the truck axle shaft before installing the assembly. The bearing inside the assembly is sealed or shielded and does not need additional grease during installation. Over-greasing will cause the bearing to drag and heat up during operation.
Q: What is the warranty or expected service life of the SU S359-A assembly?
A: The SU S359-A assembly typically carries a limited manufacturer warranty against defects in materials and workmanship. Expected service life is 2 to 4 years in normal warehouse use depending on operating hours and floor conditions. Keep the assembly clean and dry. Inspect the bearing for noise or play every 40 operating hours. Track hours and plan replacement before unexpected failure occurs.
