Air Springs
After installing an air spring, always make sure to double check that the lower piston is mounted correctly and seated/engaged in its mounting pins/locks. Otherwise, the lower piston can break, or the air spring can dislodge from its location.
Make sure the air line is properly placed and routed. Improper air line installation can cause the air line to get stuck between the air spring and chassis components (e.g. the inner wheel housing), making it impossible to deflate the air spring through the air line.
Always inflate the air spring whilst supporting the vehicle. If neglected the vehicle weight is unevenly distributed. Consequently, the air spring can bend during the air up procedure. This puts so much stress on the air sleeve that it could cause the bladder to be pulled out of the crimping ring.
When replacing an air spring, always make sure to thoroughly check the shock absorber as well. Be aware that the shock absorber is responsible for damping, not the air spring. When the damping force of the shock absorber is no longer sufficient, the air spring needs to absorb more of the impacts which is something it’s not made for. This can cause the lower piston to crack or break off.
