How do you change the bearings on a boat trailer?
Similarly, it is asked, how often should boat trailer bearings be replaced?
We recommended to repack the wheel bearings on your trailer every 12 months or 12,000 miles. There is not a specific guideline as far as actually replacing the bearings. When repacking them with grease, you will also just want to check for any damage or wear and replace anything if needed.
Also asked, how do I know if my trailer bearings are bad?
Listen for any squeaks, grinding noises, clicking or any other sound emanating from the trailer wheels. Repeat Steps 3 and 4 for the opposite side of the trailer. If you hear any noises, the wheel bearing is defective or needs lubrication.
With standard bearings, the inner bearing is larger than the outer, but with parallel bearings they're the same size. For heavier-duty trailers there are 1.5 tonne, 2 tonne, 3 tonne sets.
