How To Check a Trailer Axle To Determine Bearing Sizes For a 5 on 4-3/4" Idler Hub
Question:
I have a 5x8 trailer with a 5 lug axle with 4 3/4 bolt pattern - how can I confirm that the axle is 3500 lb and confirm the correct pre lub part number

Expert Reply:
The best way to verify the exact weight capacity for an axle is by checking the serial number on the axle. This is found an the axle tag or possibly stamped onto the axle tube. You can also remove one of your hubs to measure the spindle with a Digital Caliper # PTW80157. These measurements will help you to determine the axle capacity, I have included an image below which shows what to measure on the spindle. Here is a the measurements for the bearings and grease seal on the Easy Grease Trailer Idler Hub Assembly # AKIHUB-5475-35-EZ-K.
Inner Bearing # L68149 (1.378" ID)
Outer Bearing # L44649 (1.063" ID)
Grease Seal # 58846 (1.719" ID)
