Troubleshooting guide
| Symptom | Possible explanation | Recommended next action |
|---|---|---|
| Hot hub | Bearing or brake drag | Stop and arrange service |
| Grease on wheel | Failed hub seal or excess grease | Inspect brakes for contamination |
| Rumbling wheel | Bearing wear or tire fault | Avoid highway travel until checked |
Canadian weather and ownership considerations
Long summer distances and water exposure can affect hubs; some sealed bearing systems are not field-repackable.
Inspect after major weather events, before long-distance trips, and when bringing the RV out of storage. Check your owner’s manual for inspection intervals; mileage and time limits can both apply.
Maintenance record checklist
- Record the inspection date, odometer and location.
- Photograph each concern and note whether it is getting worse.
- Record the component brand and model before buying replacement parts.
- Retain invoices and follow-up dates for warranty and resale documentation.
- Verify the repair in safe conditions before the next long trip.
Canadian reference resources
For recall information, check Government of Canada recalls and safety alerts and Transport Canada road transportation. For inspection and maintenance procedures, use the specific RV, chassis, axle and component manufacturers’ manuals.

Wheel bearings and Canadian roads
Gravel roads, water crossings and long highway distances all load wheel bearings. Inspect and repack on the manufacturer’s schedule, or sooner if you travel in wet or dusty conditions.
