DNL tells you a tip:
After long drives, trailer wheel bearings get hot.Before backing your boat trailer into water, give the wheel bearings time to cool.
Because that immersing hot wheel bearings in water causes sudden cooling. That can weaken the axle. It can also draw water into the hubs, thinning the axle oil. In turn, this contaminated oil can damage the axle.
Welcome to talk more about trailer maintenance’s tips， please pay attention to DNL continually.
