Yeah, mine had fairly bad wear on the RHS through the paint down to raw leather.
About 20 mins; Disconnect both battery terminals with interior light on to discharge electrical system.
Pop the two small covers off the lower quadrants between steering spokes.
Undo the 2 T30 security screws and remove.
Gently pull airbag module free, and unhook cable from tab in centre of steering wheel boss.
On the back of the airbag, unclip the tabs on the side of the 90deg yellow plug. Pull tab away from plug slightly. This will allow the Airbag cable to come free.
Release plug/s for horn/wheel controls.
Put keys in ignition to release steering lock. This will stop you from damaging locking mechanism when you undo the mounting nut.
Ensure the steering wheel is correctly centred. THIS IS CRITICAL!
Use a 19mm socket and a breaker bar to undo steering wheel nut. It is tight; so brace the wheel with one hand (or get a friend to assist if you're puny) and turn bar anti-clockwise.
Wind the nut up until it's level with the top of the thread on the steering column. Do not completely remove. (This stops you being hit in the face by a flying steering wheel)
Centre steering wheel again.
Brace knees under steering wheel, pushing up hard; as if you're going to pop it off the taper. (You won't; it's effin' tight)
Use a drift, or a 6" socket extension bar and a decent sized hammer, to hit the steering shaft. Don't club it to death; you'll collapse the column, just give it a decent hit.
Repeat and you'll feel the wheel release from the taper. Only took a couple of firm hits for mine.
Completely remove 19mm nut.
Slide wheel off gently, and it's just the reverse to refit. Don't disturb the clock spring assy behind the wheel if you can avoid it.
If you're not confident with any of the above DO NOT EVEN ATTEMPT THIS JOB!!!!
