Advanced Complete Wheel Hub Assembly for Coaster-Type Bus

Key Benefits

This Advanced Complete Wheel Hub Assembly is a direct-fit replacement designed specifically for Coaster-type buses. It provides a fully pre-assembled unit that includes the hub, bearings, seals, and studs, saving you hours of labor compared to building it from individual parts. You get a smoother, quieter ride and improved safety because the assembly is precision-machined to OEM tolerances, eliminating wheel wobble and reducing bearing noise. Choose this for a guaranteed fit, longer service life, and reduced maintenance downtime.

Pre-Assembled for Quick Installation

• Ready to bolt on: The hub comes with bearings pre-packed with high-temperature grease and seals already installed, so you just mount it to the spindle and torque the nut.
• Benefit: Cut installation time by up to 60% compared to sourcing and pressing individual components.

Heavy-Duty Construction

• Material: Made from forged steel with a hardened raceway to handle the heavy loads and constant stress of a Coaster-type bus.
• Benefit: Withstands up to 8,000 pounds of axle load per wheel, reducing the risk of catastrophic failure during a full passenger run.

Precision Engineering

• Specs: CNC-machined to a runout tolerance of less than 0.003 inches, ensuring perfect concentricity.
• Benefit: Eliminates vibration at highway speeds, extending the life of your tires and brake components.

Real Customer Feedback

I manage a fleet of 12 Coaster buses for a school district. We had one hub fail on a route, so I bought this assembly as a replacement. Honestly, the fit was perfect—no grinding, no shims needed. I installed it in under two hours by myself. The ride quality is noticeably smoother than the OEM part we replaced. My only critique is that the hub is a bit heavier than some aftermarket options, but that weight gives me confidence in its durability.”

Technical Specifications

FAQ

Will this fit all Coaster-type bus models?

This assembly is designed for standard Coaster-type buses with a 6 x 8.75 inch bolt pattern and a 5.5 inch hub pilot. Check your vehicle’s axle specifications to confirm compatibility, as some older models may have different dimensions.

Does it include the ABS sensor ring?

No, this hub assembly does not include an ABS sensor ring or tone ring. It is a mechanical-only unit. If your bus requires ABS, you will need to transfer the ring from your old hub or purchase a separate sensor kit.

How do I know if the bearings are properly lubricated?

The bearings come pre-packed with a high-temperature lithium-complex grease. You do not need to add grease before installation. However, we recommend checking the grease seal integrity after 1,000 miles of initial use.

What torque spec should I use for the axle nut?

Torque the axle nut to 300-350 foot-pounds for initial seating, then back off 1-4 turn and torque to 150-200 foot-pounds for final adjustment. Always refer to your bus manufacturer’s manual for exact torque values.
