AIR SUSPENSION - HOW TO IDENTIFY PROBLEMS AND REPAIR

Compressor Sometimes a compressor delivers insufficient air pressure. In this case the vehicle will not reach the right level, especially with extra load. Most compressors break or burn out due to a leak in the air suspension system. Therefore burn-out new compressors will be rejected for warranty. The relay must always be replaced. An old or damaged relay can also lead to a burnt-out compressor. Air Springs/ Struts The “VOSS” OE airline connector is a push in lock system. Attempts to manually tighten the connector can damage the screw thread, causing a leak. Air springs are wear and tear products, lasting 6-10 years before they start leaking. Leaking usually starts on the folding edge of the sleeve. Arnott uses Tier 1 parts for multiple components of the air spring, such as Continental for the rubber below, VOSS connectors, and heavy-duty crimping rings.

Malfunctioning valve blocks can produce similar symptoms as leaking air springs.

If a car (corner) drops 1 inch overnight, there is a leak in the system.

Air suspension system The shock absorber takes the first hit when worn out, the air spring absorbs the shock and gets damaged. A leaking shock absorber damages the rubber below.

An Arnott remanufactured air strut is renewed inside-out, remanufactured with a professional approach and high-quality components.

A leak can only be fixed by replacing the complete part (air spring).

After replacing, the engine must be started before lowering the vehicle. This ensures that the air spring unfolds in the correct shape.

Detecting a leak often only requires water and soap spray.
