Dial in the right fit by matching your axle rating, bearing numbers like L68149 and L44649, and your wheel bolt pattern such as 5 on 4-1/2. Confirm grease seal size and choose between drum or disc setups; stainless or galvanized parts handle boat trailers and salt water well. Some assemblies arrive pre-greased with seals installed, making install quick.
Yes, stainless disc brake and hub setups have held up well after many salt water trips. Galvanized options also help resist corrosion. Rinse after launches, keep fresh grease in the bearings, and confirm your seal type matches your spindle and any pressure-bearing caps you use to help keep water out.
You can if the hub size and bolt pattern match your new wheels. That swap has allowed moving from smaller to larger wheels on older trailers when the bolt pattern stayed the same. Verify tire and wheel clearances at the fender and frame, and make sure the trailer capacity and brakes are appropriate for the new setup.
Some arrive pre-greased with bearings and seals pre-installed, which can make assembly a breeze. Others include the parts but may need packing. Check the product details to confirm what's included. Before install, inspect bearings and seals for damage and make sure small parts are protected so nothing gets nicked.
Match the hub to your axle rating, bearing numbers, grease seal size, and wheel bolt pattern. Pull a hub, wipe the bearings, and read the numbers stamped on them. If numbers aren't visible, use a digital caliper to measure the spindle to the thousandths of an inch where the bearings and grease seal ride. Confirm your wheel bolt pattern, like 5 on 4-1/2 or 4 on 4, before ordering.
Confirm your bearings and grease seal size. These typically use inner and outer bearing L44649, but seals vary: 1.249" ID and 1.983" OD, or 1.500" ID and 1.987" OD. Verify your wheel bolt pattern (5 on 4-1/2 or 4 on 4). Read the bearing numbers or measure your spindle lands and seal seat with a caliper to ensure a proper fit.
