1. Spray cans of brake cleaner
2. maybe new brake shoes (Raybestos 451 PG+ are good)
3. if you are careful you can reuse the nut and retainer wedge-type clip that sets the axle bearings (tighten nut 120 ft lb, back off 1/8 turn).
4. silicone RTV to seal axle shafts to hubs, and between seal and hub for seals you replaced.
5. lacquer thinner to clean axle/hub area, hub area where seal goes.
