Soap and water on the air struts, if the compressor doesn't come on then it might be the relay which is by the compressor or the comprssor may have died. You have to either replace the leaking air strut or swap them out for the springs that a couple of people have on the market, fairly easy swap out or replace. You can use the ABS relay which is in the left (drivers) wheel well to check the air relay they are the same, hope this helped some.

It's either the control arm bushings or the rubber mounts for the shocks.
