Instead of a traditional steel spring suspension, an air-ride suspension uses compressed air springs, creating a smooth, self-leveling ride. If the Check Air Suspension signal lights up, the vehicle has detected a problem with the air suspension system, which could be caused by a variety of things.
How do you check your air suspension?
How do you know if your system is Air Ride Suspension working or has no issues:
- The car is simply in the position it should be.
- Spray the rubber boots with a soapy water mix; if it bubbles anywhere you have a leak.
- Also spray fittings, if you see bubbles this too is an indication of leaking.
Do all Lincoln Navigators have air suspension?
Navigator 2WD models use a rear air suspension, while 4WD models have four corner air leveling (both front and rear). Shockwarehouse offers OEM quality replacement air suspension components as well as conversion kits to convert all Lincoln Navigator to coil spring suspension.
If you take your Navigator into the mechanic for an air suspension failure, nine times out of 10, the air bags will be the first thing they check. The air springs in your air suspension are what keeps the car suspended off of the wheels. They are made, in part, of flexible rubber.
Your Navigator employs a ride height sensor at each wheel. These sensors determine how much each air spring needs to be inflated for the car to maintain its ride height. They are precise little components that suffer from two major setbacks: they are electronic AND moving parts.
Why is my Lincoln Navigator running too loud?
If it runs too loud or too long (more than about 10 seconds), it likely needs service or replacement. Your Navigator employs a ride height sensor at each wheel. These sensors determine how much each air spring needs to be inflated for the car to maintain its ride height.
The compressor in your Navigator runs on on/off cycles. It has a limited lifespan. Therefore, when other components are failing and the compressor tries to pick up the slack, it significantly shortens its own working life. For this reason, the compressor often goes out in air suspension systems.
