I did the wheel bearings myself using a borrowed SIR tool set. The only part I wasn't able to do myself was remove the inner bearing center from the hub after I pulled it, but only on the backs (2000 S), so I dropped them at my mechanic and he cut them off for me. I don't have any grinding/cutting tools or a good vise to hold stuff.
