Frequently Asked Questions
Q: What is the difference between SU 153-XL and SU 153-XL-A?
A: SU 153-XL is the wheel component only. SU 153-XL-A is a complete assembly that includes the 5-inch diameter wheel, steel hub, greaseable bearings, and fasteners pre-assembled. If your truck uses individual wheel replacement, order SU 153-XL. If your truck requires complete assembly replacement, order SU 153-XL-A. Check your truck documentation to determine which is correct.
Q: Does the SU 153-XL-A assembly have greaseable bearings?
A: Yes, the SU 153-XL-A assembly features greaseable bearings. Apply wheel-rated lithium grease monthly or per your truck maintenance schedule. Under-lubricated bearings will wear prematurely and seize. Over-greasing can cause overheating and bearing damage. Use the grease quantity specified in your truck manual.
Q: Is the SU 153-XL-A suitable for freezer and cold storage applications?
A: SU 153-XL-A polyurethane wheel compound is usable in freezer environments but becomes stiffer and less grippy at low temperatures. The steel hub and greaseable bearings are compatible with cold environments when cold-rated grease is used. For dedicated freezer truck use, verify your truck specifications for cold-environment wheel requirements before purchasing.
Q: How do I replace the SU 153-XL-A assembly on my truck?
A: Raise the truck and secure it. Remove bolts holding the old assembly to the truck frame. Slide the old assembly off the mounting bracket. Position the new SU 153-XL-A assembly and align mounting holes. Insert bolts and torque to truck manual specifications. Verify the assembly spins freely and does not contact the frame. Do not operate the truck until all assemblies are installed and torqued correctly.
Q: What load capacity is the SU 153-XL-A rated for?
A: Load capacity depends on your complete truck design and the number of load wheel assemblies. The SU 153-XL-A alone does not determine truck capacity. Refer to your truck specifications for maximum load rating. Always replace all load wheels with identical specifications for balanced handling and safety. Using mismatched assemblies can cause steering problems and reduce truck stability.
