I did mine, and iy still sings from time to time. I replaced the seals w/ a kit from CJs. What happened is thst I was removing the rotor assemble and my hands slipped, next thing I knew I had slippers and springs explode all over the place. I managed to get them back in (correctly or so at least I think so) and put everything back together. The power steering works great and doesn't leak, it just gets noisy sometimes. I don't know if the slippers were put in wrong (akin to camshaft and lifters) or if there is a way to bleed the system.
