I always believed that the reason my car gets lower in the back when parked for more then 12 hours been due to a small air leakage some where on the rear suspension components. But now I'm not that sure anymore. It looks like the air from the rear air struts gets transported to the front ones. Because as much the car gets lower in the back, it gets higher in the front. See picture below.


(Not the best picture to show the problem. It gets more obvious when parked for a longer time)

Anyone have any idea what can be wrong? This is not really a serious problem because as soon I start the car up it raises the rear and lowers the front. But if it is a easy and not that expensive to fix I would like to take care of it because it feels like this could be bad for the airbags if I had to park the car for a long amount of time. Attached is a pdf with the air suspension components if that helps to pin down the problem.

Thanks!

I like the look with the lowered back ! Good luck with solving the problem.

Those wheels make your car look like it has truck or ATV tires on.

I know. It's winter tyres which you must have when it's winter (yes it's winter now!) if you live in the part of Sweden that I live. And because of the quite huge price differens between 16 and 17 inch wheels I went with 16 inch 225/60 tyres. Safty is more important then style for me. My summer wheels are 17 inch though.

looks quite normal, if you load a car with normal suspension it will act the same. front gets higher too. you should take a look at this picture:



I think the same is happening too your Lexus when the rear shocks loose thier pressure.

However, maybe you're right. But front and rear are seperated by at least two valves

Asia-HT: You can be right. It's the most logical explanation. But, heres why I'm confused. When I starts the car up. It first raises the back and after that is done it lowers the front.

check the ride height sensors on the (iirc) front drivers side and rear passenger side suspensions.
