Not really. The airbag is nice and secure to the A pillar. The 'Airbag' label covering the screw on the trim can be a bit of a swine to get off without damaging though.
When replacing the A pillar trim you have to engage a clip as you're sliding it into the two slots on the dash while feeding the rubber trim around it. I found it was easier to do from outside the car and looking through the screen. You'll know if it's right because you can compare how flush it is with the dash with the passenger side.
Hope that makes sense.
