I was reading through my new to me Green Manual. Just as an example, it stated that the rear axle nut should be replaced if removed? This seems a little ridiculous. My axle nuts for example on my BMW have been taken off thousands of times since 2000 and are still doing what they should. I have not read through the entire manual obviously so I am sure that there will be other items that they say to replace. What are you guys' thoughts? Thanks.
