Over the years I have considered all manner of jacking systems but have always come back to the simplest one that I have used for about 50 years. It is a quality floor jack and four inexpensive jack stands. I bought the jack at Sears around 1970, back when they were quality made in the US, had the hydraulics rebuilt once since then. I jack up one frame rail and place a stand near the front and rear and then do the other side. With the jack pulled out there is a a lot of room to work , as opposed to any alternative setup that I have seen. I don't do this often, just for my brake and clutch fluid flushes every two years and a front wheel bearing pack and disc pad replacement every ten years or so. For once a year
oil changes (engine, trans, rear) I sometimes get lazy and just jack up one side but I find it makes life a lot easier to do the four stand routine. I can easily afford any jacking alternative but I still like my system the best.
