I've heard others say that it is safer with the jack stands, but never understood why. It would seem that having the wheels engaged on the ramps would provide a more stable platform than the axles engaged on the jack stands. Is the issue that the ramps may fail or that they may slip or that the truck may roll off? I'm anticipating having to really work to get the master cylinder off of the truck and am concerned about being under it while it is on the jack stands and pulling hard on a socket wrench.
