Determining Correct Hub Assembly For Boat Trailer With 2000lb Axle

Expert Reply:

There are two different bearing combinations commonly used on 2000lb trailer axles, so determine which hub assembly will be correct for your trailer you will need to confirm which bearing combination your trailer has.

The easiest way to do this is to remove one of your current hubs and look for the bearing number stamped in the face of the bearing as shown in the picture of the # L44649.

If your bearings are worn to the point that you cannot read the bearing number you will need to use digital calipers like # PTW80157 to precisely measure your spindles according to the included diagram.

If your spindle uses inner and outer bearing # L44649 I recommend the Trailer Idler Hub Assembly for 2,000-lb E-Z Lube Axles - 5 on 4-1/2 - Galvanized # AKIHUB-545-2-G-EZ-2K which has the 5 on 4-1/2" bolt pattern and a galvanized finish which is perfect for a boat trailer.

If your spindles use inner and outer bearing # L44643 you would want the Trailer Idler Hub Assembly for 2,000-lb Axles - 5 on 4-1/2 - Galvanized # AKIHUB-545-2-G-1K instead.

I included videos for both of the hubs mentioned for you to take a look at.
