Didn’t trust my 2 ton jack to lift the Humvee, so today I went and bought a heavy duty 3 ton. Aired up the tires to what others have recommended for the road. And after a quick test drive, which the bounce was better but not gone, the power steering started making noise. Checked it and it had a good bit of bubbles and a little over filled. So I took my hand pump and sucked out a bunch, then refilled to the correct level with some dextron III. Didn’t have time to test. But I can see a full dump and replace in my future.
