About 12 months ago I was removing my steering wheel, well I have done this 1000's of times before but for some reason this time I removed the nut completly, so I put my arms behind the wheel and start hitting it to loosen it one hit did nothing second hit did nothing so I gave it a decent wak the third time and the wheel came off and smacked me right in the bridge of my nose and it proceded to bleed so my car gave me a blood nose.
Moral of the story is to avoid this in the future don't work on your car at 2 in the morning while
pissed and stoned and allways leave the nut on a couple of turns.
