Question:
If I send you the VIN off my trail star boat trailer would you be able to see if you have a wheel bearing kit for it?

Expert Reply:
Vin numbers cannot be used to identify wheel bearing/axle information, as they're is no database for that. The OEM trailer manufacturer's use whatever axle they have on hand that day, so it could have a few different options.
Most boat trailers have 1 of 3 possible bearing combinations, but you'll need to measure your spindle to be sure.
The first is a 1" straight spindle that uses bearings # L44643 and measures 1" at bearing points on the below diagram, and uses seal # 34823 which measures 1.249" at the grease seal point on the spindle. Bearing kit with everything you need for (1) spindle is # BK1-100, you'll need (2) per axle.
Second option is a 1-1/16" straight spindle which uses bearings # L44649 and measures 1.063" at the bearing points, and uses seal # RG06-020 which measures 1.500" at the grease seal point on the spindle. Bearing kit for (1) spindle is # BK1-150, you'll need (2) per axle.
Last is 3,500lb axle tapered spindle which uses inner bearing # L68149 which measures 1.378" on the spindle, outer bearing # L44649 which measures 1.063" on the spindle, and grease seal # RG06-050 which measures 1.719" on the spindle. Bearing kit for (1) spindle is # BK2-100, you'll need (2) per axle.
These are all pretty exact measurements so you need to use digital calipers like # PTW80157.
