1998 dse suspension fault....

Hi landy lovers... went out the other morning.. and seen the o/s/rear wheel on its bumpstop!!! .. great me thinks...so i started the car and pumped up the car to normal hight..then the next morninng i go out and the complete off side is down!!! I havnt really got a clue so can any one start me off at the begining?? any help would be great.. oh by the way there is nothing on the dash... lights or any warnings ect..

pray the arbag with water/wash up liquid mix while its on highest setting. if you see bubbles the you'll need to replace airbag(s)
