If you live in San Antonio, or south Texas, and need any trailer work done, I highly recommend Southwest Wheel Co. My trailer has Vault hubs and recently I noticed grease leaking from the back. They got it in and replaced the rear seal on BOTH hubs and repacked with fresh grease, torqued the lug nuts, and aired the tires to proper inflation (including spare). Trailers are their business, and it was very apparent, they knew what they were doing.
