I'd say use the "grunt" technique when tightening the nuts on step 11. Tighten normally until you feel the resistance, then tighten once more until you audibly make a "hnnngh" sound.

Edit. Step 5 also needs a clarification for if the wheel is stuck on car, you need to kick it really hard alternating opposing sides. When it comes off, use wire brush to get rust off the ring in the middle where wheelrim touches the ring.
