I would actually do this a different way the previous but That way also works. and if you don’t have 4 jack stands you can use 4 cinder blocks too. I would raise it up so that the wheels are off the ground and place either the jack stands or blocks under the frame and let the suspension hang.I do this so that the suspension doesn’t get soft and spongy. It may ride like a brick for awhile after to get back but that will smooth out after a few weeks.
