    Air leak in rear leveling shocks.... where to start?

    my car has to have an air leak for the rear shocks somewhere... the compressor is ALWAYS running... it'll run for like 20seconds, but goes on every 6-10minutes..... pisses me off, and I am sure not good for the compressor, and also, if the car sits for a week without being ran, it drains the battery.....

    .... Where should I start looking for a leak.... how do I find it/test it? Any help will be great. Thanks!

    Put some soapy water in a spray bottle. get under the car and spray down the connections at the shocks, compressor, tank (if applicable), and at the junctions and splices. The one (ore more) that bubble are the ones that leak.

    Water getting trapped between the boots and the metal housing created a ton of rust resulting in pinholes in the shock housing, so be sure to check with the suspension extended. My 7 year old originals finally failed there, and also leaked earlier at the o-ring at the plastic outlet fitting at the compressor pump, and at the plastic hose that got a pinhole near the lower control arm.
