Well I serviced the power steering because of a leak at the reservoir o ring. Followed instructions by jacking vehicle, Mercedes oil,and 30 plus complete lock to lock turns.I used a suction tube to remove bubbles and kept filling a littleat a time a little messy but now it's so smooth to turn. I mean with a finger did I do something wrong because it seems really easy to turn.I know this might sound strange asking this but it did seem harder to turn or more resistance shall I say to turn the wheel.
