Thanks for reaching out, Randall!

The correct replacement bearing kit for your 3,500 lb Axle Technology BD3545 axle is the #84 Spindle Hub Bearing Kit # BK2-100. This comes with the following parts:

- Inner Bearing # L68149
- Outer Bearing # L44649
- Grease Seal # 58846

I'm not sure the difference between all of those parts since we don't carry them, but the kit mentioned above is exactly what you need for your axle so you don't have to wade through a whole list of part numbers.
