Hi. I am New to the Renault 4 and just commencing a full restoration, and new to the forum. The body is off and I want to remove the torsion bars so that I can clean up all of the suspension components and re-bush them. I have the Haynes manual, and have canvassed You tube and a couple of forums, and I just want to be clear that I understand how to handle the torsion bars. Am I correct in thinking that I can take the whole front and rear suspension units out without any "special " tools to release tension on the torsion bars. I understand that once the units are out, I can re-spline the torsion bars to different height positions if I need to. Once everything is tidied up and ready to go back, roughly how much of a 360° circle does it take to re-tension the torsion bars to secure them in position? I haven't found any diagrammatic description of the rear end of the front torsion bars that is clear to me, so I want to be sure I can get this back together again. I do appreciate the information that others have put up in the past, but it's just not clear to me how far things have to be moved, and at what point these things will bite me, to do these jobs with my present knowledge. Thanks. Ian.
