I have a brand new 06 LS 340 Ultra Lux. pkg and as you all know with UL it has air suspension. so the car has been sitting for past couple of days and this morning i realize that the right rear wheel was kinda sagging it look like i had some heavy items in the trunk which i did not have any.

I then called up the dealership and spoke to one of my mechanics at the Lexus dealership and he said that this is nornal for the car with air suspension. he said it is mentioned in the service book that the car will sagg unevenly sometimes about 1 inch.

so i am just curious has anybody experienced the same problem and if so what did you guys do about it?

thanks,

Once you have the car on "level surface" then you can measure the ride height. The only true level surface is the alignment rack. Have the dealer check the ride height, I bet everything is good. Nothing to worry about.

I had installed a ride height controller and noticed that the RR corner never really changed that much, it turns out that I had a defective height sensor and a leaky shock, thankfully still under warrenty. But I wonder what would have happened if I hadn't brought it to their attention??? Anyway, they (the dealer) relplaced both parts and adjusted the height sensor and it was perfectly level after that. If I were you, I'd measure it several times over several days to se if it's always lower, and then take it to the dealership and insist that it be leveled.
