It's pretty straight forward. Disconnect your batteries and have a soda or coffee so the capacitors in the air bag will go "dead". then just take the air bag off the steering wheel gently. Make sure you have the wheels pointed straight and remove the steering wheel. You may need a steering wheel puller. clock spring is underneath the mounting plate. I have "match marked" the wheel and the colum splines before removal. then put it back together..How do you know the clock spring is bad?
