yes and no the airbag unit will pop out allowing access but there is not a great amount of room to fiddle around with the front section plus the airbag is clipped in on spring clips and unless you know how to do them then you are likely to damage it (not a good idea)
Thanks for the reply - you have probably put me off tampering with it !
Unless - I can work out how the springs fit before I take it off - like find one at a scrap yard without the split and examine it ?
I have same problem. When I rang local vauxhall garage it was hard to explain what I was on about, so he could not find the right part without me taking it in. the only part he could find that was not the cmplete steering wheel was a part for the horn which I am not sure is correct. Anyone had any success getting the replacement part (please post part no.) and fittting it themselves?
