When you replace the bearings and seals, you have replaced the parts that wear. So getting a used hub that hasn't been cross threaded, or ran until the bearings have disappeared, is close to getting a new one. Whether you or a shop do the work, make sure they are torqued to factory specs. Most do not, the first time. 150 psi seems unreal. And it takes a special socket that costs 50 bucks (and it isn't hard to break off one of the tabs around 125 psi, so keep it square).
