Frequently Asked Questions
Q: What is the difference between SU S9123-EZ and SU S9123-EZ-A?
A: The SU S9123-EZ-A is a complete wheel assembly including the wheel, bearing, and axle assembly. The SU S9123-EZ is the wheel only. Order the -A version when replacing the entire assembly. Order the wheel-only version if you need to replace just the polyurethane wheel and reuse existing bearings and axle hardware.
Q: Is the SU S9123-EZ-A assembly pre-lubricated?
A: Most OEM wheel assemblies ship with sealed or shielded bearings pre-packed with grease. Do not re-lubricate sealed bearings as excess grease causes heat buildup and premature failure. If bearings emit grinding noise after installation, the seals may be damaged and the assembly requires replacement.
Q: Can I mix the SU S9123-EZ-A assembly with other brand wheels on the same truck?
A: Do not mix different wheel brands or designs on the same axle. Mixing causes uneven load distribution, steering drift, and accelerated bearing wear. All four wheels must match in diameter, width, durometer, and tread condition. Always replace wheels as a complete set for safety and performance.
Q: What tools are required to install the SU S9123-EZ-A assembly?
A: Installation requires a socket set for axle bolts or pins, a hex key set if using socket-head fasteners, and a pry bar or wheel puller if the assembly is stuck. No welding or specialized equipment is needed. Replacement typically takes 15 to 30 minutes per wheel. Ensure the truck is lifted safely before removing wheels.
Q: How do I verify the SU S9123-EZ-A assembly is properly installed?
A: After installation, spin the wheel by hand and confirm free rotation with no grinding or catching. Verify axle bolts or pins are fully secured and cannot rotate. Check that the wheel sits evenly in the frame with no wobble or lateral play. Test drive slowly and listen for noise or vibration indicating improper seating.
Q: What is the warranty on the SU S9123-EZ-A assembly?
A: Warranty terms depend on your supplier and purchase date. Typical coverage is 30 to 90 days against manufacturing defects such as bearing failure or cracked wheel upon delivery. Wear and tear from normal use is not covered. Retain your receipt and contact your supplier if the assembly fails within the warranty period.
