Frequently Asked Questions
Q: What is the difference between GW 9150 and GW 9150-A?
A: The GW 9150 is a wheel-only replacement without bearings. The GW 9150-A is a complete load wheel assembly with pre-installed bearings and a machined steel core, ready to mount directly onto your truck spindle. If you already have bearings or plan to source them separately, order the GW 9150. If you want a plug-and-play assembly, order the GW 9150-A.
Q: What bearing size is installed in the GW 9150-A assembly?
A: The GW 9150-A comes with 25mm bore (approximately 2.047 inch) sealed bearings pre-installed and ready to use. The bearings are matched to the wheel and do not require adjustment or greasing. Do not attempt to replace or lubricate these bearings, as they are sealed for life.
Q: Are the GW 9150 and GW 9150-A cross-compatible with each other?
A: Both the GW 9150 and GW 9150-A fit trucks with 25mm spindle bores and can be used on the same truck fleet. If a truck currently runs a GW 9150-A assembly and you want to replace it with a GW 9150 wheel, you must transfer the existing bearings to the new wheel or source compatible 25mm bearings. Verify bearing condition before reuse on a high-mileage truck.
Q: What is the outer diameter and width specification of the GW 9150-A?
A: The GW 9150-A has a 3.25 inch outer diameter and 2 inch tread width. Note that this is different from the GW 9150 wheel-only specification of 5 inch diameter. Verify which wheel size your truck requires before ordering. Installing a 3.25 inch diameter wheel on a truck pocket designed for 5 inch wheels will cause instability and load failure.
Q: How long does the GW 9150-A assembly last in continuous warehouse operation?
A: The GW 9150-A typically lasts 1.5 to 2.5 years depending on floor surface, truck load capacity, and operating speed. Inspect the wheel quarterly for visible wear, cracks, or hardening of the polyurethane tread. Once the tread becomes glossy or the wheel shows flat-spotting, replacement is overdue. Worn wheels create pulling, drifting, and increase stopping distance under load.
Q: Can I install the GW 9150-A on my truck without special tools?
A: Yes. The GW 9150-A slides onto the spindle and is secured with a snap ring. You need a rubber mallet to gently tap the wheel onto the spindle and a snap ring tool or small flathead screwdriver to seat the snap ring in the spindle groove. Do not use a hammer or apply excessive force, as this can damage the bearing shields. If the truck has an axle nut, do not tighten it beyond hand-snug pressure.
