Changed my first air bag.

Nice job. Keep learning. Get a full set of open end wrenches and 1/2inch drive socket set. Not sure what truck you have but I would probably get standard and metric. Up to 24mm or 15/16

 

Means that unless that bag was ruptured by a tire exploding on/near it, the other air bags are all due to be changed as well (if its just wear and tear, then it is frequently dry rot and the others are probably near that point)

 

Meaning when 1 fails the others are not far behind. Same with brake chambers one fails change them all. They all get the same amount of wear. Cheaper to do them all at once. On your schedule. Rather than Billy bobs bend ya over road service
