AIR SUSPENSION FREQUENTLY ASKED QUESTIONS

AIR SUSPENSION FREQUENTLY ASKED QUESTIONS

What is a good way to inspect my Air suspension?

First, start by identifying type of failure you may be having which will lead you to the culprit behind the failure. Things to look for are:

 

  • Listen For Clicking, Grinding or abnormal sounds coming from the compressor – A weak compressor can cause multiple ill effects on suspension.
  • Listen for compressor turning on and duration of the operation – verify your compressor is operational and make sure it is running, if it will not kick on the first thing to check is the compressor relay.
  • Inspect vehicle ride height – inspect all 4 corners and make sure they are all evenly raised if one corner seems lower that may be the unit in question which will require a leak test (see below for testing method. If the vehicle seems to be riding lower on all corners with air springs, then the problem will most likely be coming from the compressor end.
  • If you can hear the compressor running constantly – you will need to remedy the leak before the compressor fails since this will add extra stress to the compressor, proceed by performing a leak test.
  • Sagging and bottoming out air springs – if you are experiencing decreasing ride quality and feel the car swaying, nose-diving or feel the road in the cabin, you will want to inspect your air springs for dry rot, cracks, and leaks. When the rubber on your air spring begins to rot they will no longer be able to hold the factory psi capacity and will expand more. Next inspect for air leaks, keep In mind these conditions will also wear and damage the shock absorber.
  • For most newer vehicles it is good practice to do a full scan on the suspension module to find codes reported from electronic components.

Most air spring bag leaks may be found by performing a simple leak test. Start by making a mixture of 2 tablespoons dish soap to one quart of water in a spray bottle. Spray air spring bags, fittings, airlines, and compressor. Any sign of consistently forming bubbles is an indication of a leak. If there are no bubbles seen it does not necessarily indicate there is not a leak.
