Expert Reply:

In order to find the correct bearings and seals for your Shoreline boat trailer you will need to identify what you have. The first thing I would check is the axle tag. If this was made by an existing manufacturer like Dexter or Lippert they will be able to identify the axle and parts using the serial number.

If the axle tag is worn or missing, you will need to pull off your hubs to check your bearings. There may be part numbers stamped in the side, but more than likely you will need to measure using a digital caliper like # PTW80157. You can either measure the inner diameter of the bearings and grease seal or measure the spindle where the bearings ride. See the diagram below.

For example, if you found that your inner bearing was # L68149 (1.378" inner diameter) and outer bearing was # L44649 (1.063" ID) you could use bearing kit # BK2-100. This uses the # RG06-050 (10-19) grease seal and is your standard bearing combination for a 3,500 lb axle.

I have attached a link below to all of our bearings and seals which can be filtered by inner diameter for your reference.
