The clock spring is centeredon the steeringwheel so the air bag will operate correctly. If it is removed then anewone is in order. However, airbag systems should only be looked at by professionals due to the damage that it can cause the car as well as person trying torepair it. Besides this car shold still be under warranty why are you messing with it.
