For the air-bag change first put the axle on stands & remove the wheel. Then raise the chassis until you can fit a 4" or 5" block of wood between the bump stop rubber & the axle. This way the chassis cannot drop, and there's enough room to replace the deflated airbag.
Then get an old paint roller and make a tool to pull out the bag clips. Much easier than pliers.
