Fitting auxiliary air suspension is one of the best investments for ensuring a motorhome's comfort and stability, particularly on models with a significant overhang or those frequently travelling fully loaded.
However, like all equipment closely or distantly related to the chassis, air suspension systems require particular attention to maintain their long-term performance. Regular maintenance not only optimises shock absorption but also prevents costly breakdowns.
How often should the air suspension of a motorhome be serviced?
Unlike conventional leaf spring suspensions, air suspension systems are active devices that utilise flexible components and a compressed air circuit. There is no standardised mileage-based revision for suspensions, but Periodic monitoring is essential.
We recommend a thorough visual inspection at least twice a year once before the start of the summer season and once before winter storage. If you use your vehicle intensively or on poor roads, A quarterly dashboard pressure check is advised.
The essential points to check
To ensure the proper functioning of Air suspension for motorhomes, three key elements must be inspected:
- The sealing of the circuit This is the most critical point. Using a leak detector spray or soapy water, check the air fittings on the air springs and compressor. The appearance of bubbles indicates a micro-leak.
- The condition of the rubber cushions Examine the surface of the pneumatic boots for cracks or signs of rubbing against other chassis components (cables, exhaust pipes).
- The compressor and the control panel Check that the 12V compressor engages normally and that the pressure gauges or digital display show consistent values. Also, listen to ensure the compressor is not running excessively, which would indicate it is compensating for a leak.
How to clean and maintain the air suspension of a motorhome.
When cleaning your motorhome, Pay close attention to the rear axle. Use a moderate-pressure water jet to rinse the air cushions. Absolutely avoid using harsh chemicals or fatty substances (oils, greases) on the rubber of the cushions, as this could damage the material and cause it to fail prematurely. Simple rinsing with clean water is usually sufficient to preserve the integrity of the system.
How to extend the life of your air suspension?
To maximise the longevity of your equipment MCK Plug & Drive You MCK AIR-DRIVE, some good practices for use should be adopted:
- Never run empty An air spring must never be completely deflated (0 bar pressure), even when the vehicle is unloaded. Maintaining a minimum safety pressure (generally between 0.5 and 1 bar depending on the model) prevents the spring from pinching or deforming under the weight of the chassis.
- Remember maximum pressures conversely, never over-inflate the system beyond the manufacturer's recommendations in an attempt to compensate for an illegal overload of the vehicle. This would place abnormal stress on the chassis.
- Prefer an active wintering If your motorhome remains parked for several months, remember to activate the system from time to time to prevent the compressor seals from drying out.
Following this advice will help you preserve your motorhome's air suspension for many years. If you have any doubts about the condition of your equipment or for a complete service by our experts, please do not hesitate to contact us by performing a request a quote.
