Ls 430 Suspension Problem

[docsd]

I have a 2006 LS 430 UL that "droops" on the passenger side when parked for a couple of days. The passeneger side (front and rear) droops 2" below driver side. When I start the engine, within a couple of minutes, the passenger side comes up about 1/2" and the driver side drops about 1/2". After driving for even a short distance the car levels off. I have the car at the dealer for the third time to get it fixed. Informally they told me that Lexus says that some droop is okay but that doesn't mean 2 inches in my mind. Seems as if there must be a leak in the system somehwere. The car has 39000 miles. Any ideas?

Sounds like the air spring is leaking, or their's a leak in the air line on that side. Have them replace it if it's still under warranty. 2 inches it too much; I think the spec is like .1 inch per day or something like that.

Thanks. The car is still under warranty (for 2 more weeks). The dealer has had it for 5 days now and still can't find the problem. I wouldn't want them to tell me that a 2" droop is within spec and then when the cause of the droop (a leaky line?) creates a permanent droop they bill me a few thousand for something that should be fixed now. Do you know if there is a valve or something that would cause the entire side to droop? I've seen other posts where just the rear acts badly but haven't seen anything where the front and rear on just the passenger side droops--and it is exactly 2 inches.
