First get the steering alignment checked. If it's spot on, or once it's
been adjusted, *then*
make sure the road wheels are ponting straight ahead, remove the steering
wheel from the column (using a puller rather than the 'bloody big hammer'
method) and re-centre the wheel on the splines before re-attaching it
properly. Note - Probably best to let a dealer or steering shop do it if
you have airbags though! Cheers
