You will need either the Dexter Trailer Idler Hub Assembly # 8-91-05UC1 that fits standard axles, or the Dexter E-Z Lube Trailer Idler Hub Assembly # 8-91-05UC1-EZ that fits axles that have the E-Z lube grease. Both hubs will include all new bearings, races, lug nuts, a grease cap and a grease seal.

I recommend using LubriMatic LMX Industrial Strength Grease # L11390 to fill the bearings and the hubs thanks to its superior wear resistance in both hot and cold climates.
