I used 6 ton jack stands when I replaced my front flex disc. I started off on ramps, but I couldn't get all the bolts out... needed to turn the shaft to get to the last two. With the rear end on jack stands, I could turn the shaft by hand.

Be absolutely sure you mark the shaft so it goes back on in the same orientation to the flanges.
