• Increased friction and heat, causing premature tire wear and potential wheel lock-up
• Misalignment of the trailer, creating instability and swaying
• Damage to the axle and other trailer components

Regularly replacing bearings offers several benefits:

• Improved safety: Proper bearings support the weight of your boat and reduce the risk of accidents.
• Increased lifespan: Well-maintained bearings extend the lifespan of your trailer and boat.
• Smoother operation: Bearings ensure smooth trailer movement, reducing vibration and noise.
• Peace of mind: Knowing that your bearings are in good condition provides peace of mind while trailering your boat.
