Question:
How do you know what size seals and bearings to put in my boat trailer?
asked by: Larry M
Helpful Expert Reply:
There are two different ways to determine which replacement bearings and grease seals will fit your boat trailer.
The first is removing the hub and looking for the bearing numbers stamped on the face of the bearing as shown in the included picture of the # L44649, and looking for any part numbers stamped on the face of grease seal.
If your bearings/grease seal is worn to the point that you cannot read the numbers then you will need to use digital calipers # PTW80157 to precisely measure your spindle in the locations shown in the included diagram.
If you can provide the bearing numbers/seal number or the spindle measurements I would be happy to recommend the correct replacement parts for you.
