Importance of Regular Trailer Wheel Bearing Replacement
Regular trailer wheel bearing replacement prevents premature failure and extends the life of your trailer by:
- Reducing Friction and Heat: Wheel bearings lubricate and reduce friction between moving parts, preventing overheating and premature wear.
- Maintaining Proper Wheel Alignment: Worn bearings can cause misalignment, leading to uneven tire wear and reduced trailer stability.
- Preventing Seizing: Proper lubrication prevents bearing seizure, which can result in wheel lock-up and severe damage.
