I was going to order the hubs, I don't have to. As I understand it, the wheel bearing races have to be pressed in which requires a hydraulic press. The indy wants $480 to install the right side only, which should allow my ESP light to go out. Last time I changed a wheel bearing was on a W123 chassis and I just beat the races out and installed new ones and the bearings. It appears that it is much more labor intensive on the W211
