Frequently Asked Questions
Q: What is included in the SU S553-A load wheel assembly?
A: The SU S553-A assembly includes the wheel, bearing set, bearing seals, axle spacers, and pre-installed hardware. This is a complete ready-to-install package that does not require additional bearing or seal ordering.
Q: How does the SU S553-A assembly differ from the SU S553 wheel only?
A: The SU S553-A is a fully assembled unit with new bearings and seals pre-installed. The SU S553 is the wheel only and requires you to transfer or install bearings separately. Use the assembly if your old bearings are damaged; use the wheel-only option if bearings are still serviceable.
Q: Do I need special tools to install the SU S553-A assembly?
A: No special tools required. You need a socket set, jack stands, and a torque wrench. The assembly bolts directly onto the axle - no bearing press or seal installer needed because bearings are pre-mounted.
Q: What is the cost benefit of buying the SU S553-A assembly versus the wheel alone?
A: The assembly costs more upfront but saves labor and prevents bearing selection errors. If your bearings are worn or seals are damaged, buying the assembly eliminates the cost of separate bearing and seal kits, usually saving 15-20 percent overall.
Q: Can I reuse the bearings from my old wheel with the SU S553-A assembly?
A: No - the SU S553-A assembly comes with matched bearings and seals already installed and cannot be disassembled for reuse without voiding the warranty. If you want to keep your existing bearings, purchase the SU S553 wheel only.
Q: Is the SU S553-A assembly compatible with the same trucks as the SU S553?
A: Yes - the SU S553-A assembly has identical mounting and bolt patterns to the SU S553 wheel. Both fit the same truck models. Choose the assembly if bearings need replacement; choose the wheel if bearings are still good.
