2008 lincoln navigator check air suspension rear

Usually between the frame and the rear axles. A lever type device, should be fairly easy to locate. Check that the compressor is building air pressure and storage tank. Air bags not leaking and etc.

could just be a seal on the air line itself, or possibly a whole in the line or one of th eleveling air bags. gong thru the water should'nt have any effect on it,unfortunately these are just like any other part, or seal they just eventually wear out.

The buzzing is probably the compressor. You may have a bad air line somewhere. Or, you may have a bad solenoid. These can be check with an ohmmeter.

You must have a leak or its not pumping air like it should. This happened to my dads Lincoln towncar back in the day.

Under the hood there is an air compressor to fill the air bags on the suspension. With age the compressor draws excessive amps and blows the fuse. Check the fuse and see if it has popped. If so replace it. If the fuse is good ,locate the compressor and check the electrical plug to it to see if it has become corroded. If corroded pull the fuse and scrub the contacts with a brass brush untill clean. To keep it from corroding in the future apply some dieletric grease to the contacts and plug it back in. hope that helps, Rich.

sounds like the leveling switch is pooched or the compressor is pooched check both start with fuses

could be faulty compressor which pumps up the suspension,is it leaking from anywhere,causing the pump to work too hard,has it just packed up,check fuses but probably compressor

rear suspension ride leveler mslfunction. Check Air compressor function.

the air suppension has a lever on the rear axel
will want to check the lever and the sensor and make sure it hasnt come loose or bent and yes its adjustable. if it doesnt adjust you might have a bad sensor or air leak
