Why Change Trailer Bearings?

Trailer bearings play a pivotal role in supporting the weight of your boat and enabling smooth wheel rotation.

Changing bearings on boat trailer regularly is essential for preventing bearing failure, which can lead to costly repairs and even safety hazards.

When to Change Trailer Bearings

• Usage: Frequent towing and extreme conditions can accelerate bearing wear.
• Environment: Exposure to salt water or corrosive environments can shorten bearing life.
• Bearing quality: Higher-quality bearings tend to last longer.
