So my es300 has a bit of 'slop' in the steering. Has anyone ever adjusted the steering rack? there is a special tool for the locknut (part # 09617-22040 or 09617-24020) I think it is about 38mm. and then the adjuster has 2 slots in it. The locknut looks a little hard to get to,might be a swaybar in front of it. I am not sure if the special tool would ease the access. And when I do get the locknut undone do I wind the adjuster in until it tightens and then out 1/4 turn? Thanks in advance
