Frequently Asked Questions
Q: What is included in the SU S855-A load wheel assembly?
A: The SU S855-A is a complete bolt-on assembly that includes the wheel, sealed ball bearings, axle shaft, and mounting hardware. This is a plug-and-play replacement. No bearing or axle service is required at installation.
Q: How does SU S855-A differ from the standard SU S855 wheel?
A: SU S855-A is a pre-assembled unit with sealed bearings already installed and greased. SU S855 is the wheel only. If your truck has a damaged axle shaft or failed bearings, the -A assembly eliminates troubleshooting and saves 2 to 3 hours of labor versus replacing individual components.
Q: Is the SU S855-A bearing rated for outdoor or wet floor use?
A: SU S855-A uses sealed deep-groove ball bearings rated IP65, suitable for damp indoor and occasional outdoor use. Do not use in high-pressure wash or continuous wet environments. For outdoor heavy-duty applications, upgrade to the grease-packed bearing option.
Q: What is the installation procedure for SU S855-A?
A: Remove four bolts from the old assembly and unbolt the axle from the truck frame. Slide out the old assembly. Position the new SU S855-A and insert the axle. Torque bolts to 45 ft-lbs in a cross pattern. Spin the wheel freely to confirm smooth rotation before returning truck to service.
Q: Can I reuse the axle shaft from my old wheel assembly with SU S855-A?
A: No. The SU S855-A assembly includes a new axle shaft matched to the pre-installed bearings. Reusing an old shaft may cause misalignment, premature bearing wear, or binding. Always use the complete assembly as provided.
Q: What warranty coverage does SU S855-A include?
A: SU S855-A carries a 12-month parts warranty from shipment date. Bearings and axle are covered against manufacturing defects. Warranty does not cover wear from overload, impact damage, or lack of maintenance. Keep your invoice as proof of purchase.
