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.
