One more ABC question

I just got back from my dealer after he replace one of my rear struts to try and cure an ABC visit workshop message. When I went to pick the car up the left rear was still down and the light was still on, but now the power steering was real heavy. They are trying to tell me it is a sport steering and this is normal. It was not that way when I took it in. so as it stands now they are going to do the Rodeo procedure and see if that helps. does any one have any ideas?

Could be a collection of issues. There is a valve block in the rear of the car that can get dirt particles in it and not let the valve close to keep fluid in the shock. Also could be a defective new shock, but I doubt that. As far as the hard steering it sounds like the abc pump is going bad. Ask the dealer to test the pressure at the pump. The rodeo just bleeds the car of air unless they are replacing the fluid after each rodeo, that would assist in flushing out that rear block.
