Air Spring Installation

  • Before you start installing air springs, make sure you have all the necessary tools and equipment to perform the repair safely.
  • Familiarize yourself with the suspension on which you are performing the repair by reviewing the manufacturers service guide.
  • If you are in doubt about something, ask for assistance from a qualified suspension specialist, the suspension manufacturer or the air spring manufacturer; This can save you a lot of time and aggravation later in the job.

Important tips to remember when installing a new unit

  • Check levelling valve, linkage and transmission parts for wear and damage and if necessary replace the damaged parts.
  • Check that the shock absorber for leakages and take a shock absorber test. A defective shock absorber must be replaced.
  • Once the air lines are disconnected, check their entire length for cracks or other damage. Replace worn parts.
  • With the air spring removed, other parts of the air suspension become more accessible. Check for wear or damage of the frame hangers, trailing arm bushings, torque rods, the trailing arms and the air spring mounts. When it is necessary, also replace parts.
  • Check bearing for air spring bellow for external damage, deformation, sharp edges and correct fastening.
  • Before installing the new unit, clean the air spring mounting plates to ensure proper attachment to the suspension.
  • Always use new attaching bolts for the installation and observe the tightening torques. Never use old bolts, because these can fall out.
  • Check the linkage of the levelling valve to see that it is functioning properly. Under load, the linkage should move from the neutral position up to the intake position. This lets air into the springs, which brings the arm back to the neutral position. This lets air into the springs, which brings the arm back to the neutral position. That opens the exhaust valve, allowing air to escape until the arm returns to the neutral position. Then check the driving level.
