Frequently Asked Questions
Q: What is the difference between SU 376 and SU 376-A?
A: SU 376-A is a complete load wheel assembly, meaning it includes the wheel (5.000 x 3.000 inch) pre-mounted on a hub or axle bracket, ready for installation. SU 376 is the wheel only. Use SU 376-A if your equipment requires a bolt-on assembly or if the original axle assembly is damaged. Use SU 376 if you only need to replace the wheel itself on an existing hub.
Q: What tools and safety steps are needed to install SU 376-A assembly?
A: You will need a socket set, wrench, and jack to safely lift the truck. Always engage the parking brake and block the wheels before starting work. Lift the truck using the designated lift points only. Remove the four mounting bolts (sizes vary by model), slide the old assembly out, position the SU 376-A assembly, and install the mounting bolts. Tighten bolts in a cross pattern to ensure even pressure. Do not lower the truck until all bolts are secure.
Q: How long does SU 376-A assembly typically last before replacement?
A: Lifespan depends on usage hours and load weight. Most Cushothane assemblies last between 1000 and 3000 operating hours under normal conditions. Inspect monthly for cracks, flat spots, or noise. Replace SU 376-A when rolling resistance increases significantly, steering becomes difficult, or the wheel shows visible damage. Worn assemblies create vibration that can damage truck frames and batteries if left unaddressed.
