It features a five-lug demountable mounting configuration and includes the required mounting bolts and wedges.

R&P Service Insight

Mobile home running gear is application-specific. Confirm the complete hub, brake, spindle and wheel configuration before ordering replacement components.

Check the wheel system: This hub is designed for a True Demountable wheel, not a conventional trailer wheel.
Check the brake size: The matching brake assembly must use a 12" drum diameter and 2" brake width.
Check the bearings: Bearings, races and the grease seal are not supplied with this version and must be matched separately.

R&P Knowledge Hub

Compatibility: Intended for compatible 4,400 lb True Mobile Home axle applications using a five-lug demountable wheel system and 12" × 2" brakes.

Wheel-System Fit: A demountable mobile home wheel is retained with separate bolts and wedges. This differs from a conventional trailer wheel that mounts directly over wheel studs and is secured with lug nuts.

Installation Notes: Inspect the spindle, brake assembly and wheel-mounting components before installation. Select bearings, races and the seal according to the actual spindle and hub requirements.

Ordering Insight: Buyers needing the bearings and seal should review the complete MHD-122459-RCB-KIT version instead of purchasing this hub and drum by itself.

Brand & Fitment Note

Selling Part Number: MHD-122459-RCB

Application Reference: Dexter 8-222 and 8-222-24 are provided as replacement application references. They do not indicate that this product is a Dexter-branded component.

What This Means: This listing is for an aftermarket mobile home hub and drum assembly designed for compatible applications where the physical measurements and mounting configuration match.

Before Ordering: Verify the 12" × 2" drum size, five-lug demountable wheel system, axle application, spindle dimensions, bearing numbers and seal requirements.

R&P Repair Insight

The demountable wheel design is the most important distinction when identifying this assembly. A matching brake-drum diameter alone does not confirm fitment.

Confirm the mounting style: The wheel must use the matching bolt-and-wedge demountable arrangement.
Inspect reusable parts: Examine the spindle, brakes and wheel components for wear or damage before installing the replacement drum.
Do not assume bearing fit: Bearing and seal requirements must be confirmed from the existing components or measured spindle surfaces.
