Gear lube in Brakes!!!

Pull the axle, get a new set of seals and the pressed on retainer, take it to a shop and get the retainer off, get the new stuff pressed on, reinstall the axles, replace the brake shoes on both sides... yeah no biggie. just a day of my time and 100 bucks from a problem I think was caused by a shop that does nothing but rear end and axle work...
