I know this seems to be a dumb question. I don't want to take too much apart at one time until I am used to it. I want to change the diff fluid in the rear. I thought there was a quick way to get in there but I am confused looking at it all. What do you need to do to get to it the quickest without taking too much apart? I thought there was a video showing step by step and taking it out but I can't seem to find it. I just don't want to spend alot of time taking things apart I don't really need to. Thanks in advance.
