Frequently Asked Questions
Q: What is the difference between SU S9117 and SU S9117-A?
A: SU S9117 is the wheel core only. SU S9117-A is the complete wheel assembly - it includes the wheel with hub, bearings, and seals pre-installed and factory-aligned. Use SU S9117-A if you need a complete replacement. Use SU S9117 only if you are replacing just the tire rubber on an existing hub and bearing set. Do not confuse the two - ordering the wrong part causes installation delays.
Q: Is SU S9117-A a plug-and-play replacement?
A: Yes, mostly. Remove the old wheel assembly by unbolting it from your axle. Slide the new SU S9117-A onto the axle and reinstall bolts. Tighten to the truck manufacturers specifications - typically 45 to 65 foot-pounds depending on axle diameter. Do not over-tighten or under-tighten bolts. Verify the wheel spins freely with no drag before returning the truck to service.
Q: Do I need bearing puller or special tools to install SU S9117-A?
A: No. SU S9117-A comes with bearings already pressed on the hub. You need only a socket set, wrench, and torque wrench to remove the old assembly and install the new one. Do not attempt to press off or press on bearings yourself unless you have bearing press equipment. Factory-pressed bearings are sealed and aligned. Improper bearing installation voids the warranty and causes immediate failure.
Q: How do I verify the bearings are installed correctly?
A: After installation, spin the wheel by hand. It should rotate smoothly with minimal resistance and no grinding noise. Listen for any clicking or popping, which indicates improper seating. Bearings should be snug but not locked up. If you feel drag or hear noise, stop using the truck immediately. Verify the part number on the wheel matches your order - wrong bearings for your axle cause this problem.
Q: What is the service life of SU S9117-A?
A: Most SU S9117-A assemblies last 1500 to 2500 operating hours depending on load, floor surface, and maintenance. Rough concrete or outdoor use shortens life. Proper inflation (if pneumatic), clean operation areas, and weekly inspection extend service life. Replace when tread is worn to 1/8 inch, or if bearings develop play. Do not attempt to repair seized bearings - replace the entire assembly.
