Rear strut replacement, all tools needed, including millimeter sizes

Along with the basic wrenches/sockets you'll also need a strut spring compressor and the knowledge to use it safely. I couldn't list every exact tool size needed off the top of my head and it's unlikely anyone else can. If you don't have any tools I assume you have little experience and doing a strut can be dangerous. It sounds like something you should have a shop do.

I would have to agree with the other answer. Not very practical or possible to predict every tool you will need to do ANY job. If you don't already have the tools needed you will be money ahead paying someone to replace the parts vrs buying the necessary tools. And, as stated, coil springs can be dangerous if not handled properly. The rears springs have much less tension than fronts, but they still need to be handled with care and caution, and replaced using proper equipment. Part of the reason shops need to charge what they do, is because they have all the tools and knowledge to do what you are asking. Sorry I can't be more help, that was not a very concise question.
