We don't offer a kit for that hub, but we definitely have the bearings and races and possibly the seal which can be purchased individually.

You'll need the # LM67048 bearing, its # LM67010 race and the # LM11949 bearing and its # LM11910 race. I don't have enough information to determine the grease seal you'll need, but it'll have an outer diameter of 2.328 inches. We offer two seals with this OD. You can determine if one of them will work for you by using a digital caliper like # PTW80157 to measure the spindle diameter where the seal rides. You'll want to choose a seal with an ID slightly smaller than the spindle diameter, so the grease stays in.

The # 010-180-00 seal has a 1.68 inch ID, and the # 10-42 has an ID of 1.75 inches.

If you're not familiar with the process, I've linked to a help article that explains how to replace the bearings, races and seals on a trailer hub.
