How To Determine Which Spare Hub Assembly Is Correct For Spartan Sport Boat Trailer
Question:
Hi guys, I have a spartan sport trailer boat trailer that i use for my 15foot Lund boat. Im getting ready to take the boat on vacation with the family and am looking for a complete hub and bearing assembly to have a s a spare. I just greased the bearings and spun the wheels and and checked them for any movement and they seem to spin well and sound good. I dont want to be that guy on the side of the road. Do I need to take the hub off to determine what i need? Thanks for your help

Unfortunately we do not have a breakdown of the specific components for your Spartan Sport Trailer, so you will need to remove one of your hub assemblies.
With the hub assembly removed you will need to look on the face of both the inner and outer bearings for the bearing number. This will be stamped in the face of the bearings as shown in the included picture of the # L44649.
If your bearing numbers are not readable you will need to use digital calipers # PTW80157 to precisely measure your spindles in the locations shown in the included diagram.
If you can provide the above information I would be happy to confirm the correct spare hub assembly for your trailer.
