Nothing special about Airstream axles, bearings and brakes. They are off the shelf units that can be serviced at any competent brake or tire shop. I take my trailer to a local shop “Southern Tire Mart” that specializes in big rigs. Many of the RV dealers around here take their trailers to them for axle and tire work. They are located just off Highway 10 at the Woolmarket exit Biloxi, MS.
