Yeah, Bearing Buddy. A VERY good idea, but they have to wear the BB Bra's that they sell. Just a flexible cap that goes over the spring/zerk area. What the Bra does, is keep dirt out of the spring area. If the spring can't move as designed, it either won't keep a little pressure on the grease so water can't get in. Or, it'll allow enough pumping pressure to pop the inner seal.
BB also sells "Spindo Seal Kits" that put a stainless steel sleeve on the seal surface. Requires a different seal, part of the Kit, but it keeps a rust pitted seal surface from damaging the seal itself.
