This forum has been a great help to many of us DIY’ers. Unfortunately, it has also made some people to lose their common sense!!!!! Sugarwood insisted using the wrong thick wall 27-mm socket but I had successfully used a similar thick wall 27-mm socket from my impact set for removing the steering wheels of SC’s and Carrera 3.2’s gazilion times before.
You could use a thin or thick wall socket, 6-Point or 12- point socket as long as it clears the opening. The thick wall 6-point 27-mm socket shown in my picture was taken from a Sears Craftsman impact socket set with an OD of 38.2 mm. See pictures below:
The first thing that should had come up to OP’s mind was why were people able to use a 27-mm sockets and mine did not work? What is difference between my 27-mm socket and theirs? What is the largest OD of the socket I could use? All these simple questions could be readily thought by experienced people or have good imaginations. But some might think these as rocket science (?). I believe common sense will be more than sufficient to over come such obstacle. My two cents.
