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.
