The inner diameter of bearing # L44649 is 1.063 inches. The inner diameter of bearing # L68149 is 1.378 inches. Both fit on a #84 spindle.

The matching race for bearing L44649 is # L44610. And the matching race for bearing L68149 is # L68111.

These bearings and races along with a grease seal associated with them (10-19 seal), cotter pin, and tang washer are available together in a kit, # BK2-100. The seal inner diameter is 1.719 inches.

The wheel mounting flange of the part #20545I-EZ-60-10 is too small for 15 inch wheels. You would need to get this axle #20545I-EZ-60-15 that comes with hubs compatible with 15 inch wheels.

Answer 9

The axle part #20545I-EZ-60-10 that you referenced has a 1-3/4 inch diameter and the #K71-384-00 is designed for a 2-3/8 inch axle so that would not work. What you could use is the #TRSS175 as it is a spring seat confirmed to work on this diameter…

Trailer hubs have two bearings, one is referred to as the inner bearing, closer to the trailer. The outer bearing is the one furthest from the trailer. If we have both of these bearing numbers we can identify which spindle or hub is needed. So far…
