Bearing kit contains the following, two L44649 taper cones, two L44610 taper cups, and one double lip oil seal w/garter spring
It is advised to pack your trailer bearings in the fall rather than the spring as water may be trapped in the hubs from summer time usage.
Avoid launching your boat trailer into cold water when immediatley pulling off the highway, let the axles cool first. Otherwise thermodynamics will likely draw in cold water, either overpowering your grease seal and/or your dust cap, resultantly flooding your wheel hubs grease chamber.
