Working on suspension and drive train stuff takes some planning. You must have a safe and stable platform. The alternative is too ugly to even think about. I had a station wagon fall while I was under it. I was just lucky. That is all there is about it. 1/2 inch to the right or the left and I would be gone. I had plenty of time to think about it while my friend was lifting that car in a dead panic. Jack stands and a good jack are the best money you can spend. With a flat concrete floor you can use a stack-able system as posted above. What ever you use remember that big heavy and awkward stuff will be moving around under there with you. And when you do put a wrench on that stuff the truck must stay put, even with a 4 foot cheater on that handle. Stay safe and enjoy the work.
