There's a big nut in the middle, which I can remove but it's still stuck fast, was wondering if I needed to get a puller/slide hammer???

Any advice appreciated!

 

if u can get the nut undone all u need do i use the flat of your hand on the underside of the steering wheel..hitting opposites sides of the wheel.
it may take a little bit of effort but using hammers & bits can go drastically wrong....

 

Leave the nut on a couple of turns so you don't get steeringwheel-in-the-head injuries

 

Just whack it from behind

 

if you got a rubber mallet just tap it but leave that bolt in a few turns or when you hit the wheel with your hands it will end up hitting you in the face

 

Undo nut put key in the ignition before try to remove the steering wheel then tap with hand from back of wheel

steering lock holds wheel on
