Frequently Asked Questions
Q: How do I identify when the SU S372 load wheel needs replacement?
A: Replace the SU S372 if you observe uneven wear patterns, flat spots, cracks in the wheel surface, or difficulty steering the truck. The wheel should roll smoothly under load without resistance or vibration. If the truck pulls to one side during operation or you hear squeaking from the wheel assembly, the bearing or wheel has likely failed and requires replacement.
Q: What is the difference between SU S372 and SU S372-XL?
A: The SU S372-XL is the extended-size version of the standard SU S372. The XL version provides a larger load-bearing surface and is designed for heavier-duty applications or trucks with higher capacity ratings. Do not interchange these two wheels as they have different bore dimensions and mounting specifications.
Q: Can I install the SU S372 as a direct bolt-on replacement?
A: Yes, the SU S372 is a direct bolt-on replacement for compatible truck models. However, verify your truck model and serial range before ordering. Check the existing wheel bore diameter and width to confirm fit. Installation requires removing the axle pin and sliding the old wheel off, then installing the new SU S372 and securing with the axle pin. No special tools are required beyond a basic socket set.
