Frequently Asked Questions
Q: What is the difference between SU S9164-XL and SU S9164-XL-A?
A: SU S9164-XL is the wheel only. SU S9164-XL-A is a complete assembly that includes the polyurethane tread wheel molded on a steel hub, ready for direct installation onto truck axles. If you need just the wheel component, order SU S9164-XL. If you need the assembled, ready-to-mount unit, order SU S9164-XL-A.
Q: Does SU S9164-XL-A replace SU9164?
A: Yes. SU S9164-XL-A supersedes SU9164 and is equivalent to SUS9164-XL. Confirm your truck model and existing wheel bore diameter before ordering. If your truck originally used SU9164, SU S9164-XL-A should bolt on directly, but verify axle bore and width specifications to avoid installation problems.
Q: Can I install SU S9164-XL-A myself, or do I need a technician?
A: Installation difficulty depends on your truck model and condition. The assembly slides onto the truck axle and is held in place by snap rings or bolts. If you have basic mechanical skills and the correct tools (snap ring pliers, impact socket, or torque wrench), you can install it. If axles are corroded or stuck, have a professional remove the old wheel assembly first. Always wear safety glasses and work on a level surface.
Q: What tools are needed to install SU S9164-XL-A?
A: You will need a snap ring plier set (if your truck uses snap rings), an appropriate socket and ratchet wrench for axle bolts, a torque wrench if the truck manufacturer specifies torque values, and possibly penetrating oil if the axle is corroded. Consult your truck service manual for exact fastener specifications and torque settings. Do not over-tighten, as this can damage the hub bore.
Q: How do I know if SU S9164-XL-A is worn out?
A: Replace SU S9164-XL-A if tread depth is below 1/4 inch, visible cracks or chunks are missing from the tread, the wheel wobbles on the axle, or the truck pulls to one side during operation. Worn wheels cause uneven truck steering, increased battery drain, and accelerated bearing wear. Do not continue operating with severely worn wheels.
