|---|---|
| Screeching or grinding noises | Overheating |
| Excessive play in the wheel | Bearing seizure |
| Vibration or shimmy while towing | Premature tire wear |
| Grease leaking from the hub | Axle damage |
| Benefits of Regular Trailer Hub Bearing Maintenance: | Consequences of Neglecting Maintenance: |
|---|---|
| Extended bearing life | Increased downtime |
| Reduced towing noise | Costly repairs |
| Improved fuel efficiency | Safety hazards |
| Smoother ride | Legal liabilities |
Success Story:
"I was towing my camper to the mountains when I heard a screeching noise. I immediately pulled over and found my trailer hub bearing was shot. Thanks to my regular maintenance, I was able to replace the bearing and get back on the road in no time." - Linda, avid camper
