Default wierd air suspension problem.

Guys,
I figured I'll ask if anyone else has had the same scenerio. my 92 ls has air suspension. just last month when i saw the car in the morning the rear of the car was so low that it was almost touching the ground. well almost ofcourse ! so i figured it had to be the air suspension problem. took it to the dealer. they changed one of the shocks said that should fix it. broght it back home. next day same problem. They put in the dye to see where the leak was. tech said the o-rings needed replacement. so did that. same thing again. this is the lexus dealership where i'm taking the car for service. anyhow the last time it was in the shop they said they changed the valve that monitors the height of the car. that still hasnt cure the situation. Now the only thing that comes to mind is that the tech only replaced one of the rear shocks. and the other one is still old. the thing that i'm confused about is, isn't there a way for the dealership to find out of the shock is bad or not ? more over if one shock is new and the other one old, perhaps gone bad, would the car's height be lowered the same level from both sides on the rear ? shouldn't it just lower from the side that has the bad shock ?
any ideas would be appreciated since i need to take it back to the dealer and they're clueless at this point.
thanks.

Perhaps u have two bad shocks. You only change one and one good shock will not able to hold all the weight. I would suggest change your Air suspension shock to standard springs. Fix the problem forever. One AS shock cost a much as all for springs and struts.

Hi,
Could either of you let us know how you're going to convert? In this forum, someone said it's not a straight bolt-on, but can be done. Are you getting the $1200 quote from lexus dealer? is that parts/labor? any help would be appreciated. My '92 has air and will go bad one of these days.....
thanks.

JC
