I measured the vehicle elevation (ground to top of underwell) at each tire. I ensured the tire pressure was identical for all tires and the measurment point used was the perpediclular point to tje vehicle's axle as per the Lexus logo on the rim. All the elevation numbers are different for each tire with the plane of the chassis sloping consistently to the rear passenger tire.

In the past year the vehicle has had the 2 rear elevation senors replaced and the rear passenger air strut went as well luckly under warranty but my extended warranty is up at the end of the month.

Something is not right but before I take it in the dealer does anyone have any thoughts on the situation.

Observations for the height difference are as follows with rear passenger side being the lowest and given the 0 value:

Driver Front : + 1 1/2"
Diver Rear : + 1"

Pass Front: +3/4"
Pass Rear: 0

Thanks

 

You need your airsus recalibrated... Dealer should know how and proper values.

Also, on LS430 with airsus height is measured from ground to center-axis of lower suspension bolts...

 

You can kind of level it yourself from what I was reading. Turn car on set to "Hi," then set to "Norm." Then shut car off, and drive up 10ft and then reverse 10ft on level flat surface. This sometimes recalibrates the suspension. From what I've heard...

 

apparently this is a pretty common issue. anyone knows how much it costs at the dealer to get it re adjusted?

 

It's going to cost you a few hours labor at a minimum and whatever else Lexus would decide to charge. They would ultimately need to calibrate or even replace the height sensors (from my research it's a certain Ohm factor that keeps the car at it's heights). Or mabe they'll never be able to fix this issue....

 

On the other side of spectrum - usually Lexus shops include this procedure in all-wheels alignment. And price should be in same range.
