I purchased a 2008 LX570 with 225,000 kms on it last week. I have since had the dealer replace every last fluid on the vehicle including the AHC fluid. Despite the Lexus dealers pre-purchase inspection saying the AHC was fine I am finding that while the vehicle will raise up it struggles to come back down. No lights or messages appearing to indicate a problem. In particular I notice that the rear-left side of the vehicle jacks up much higher than the rear right in H setting, with the top of the frame almost level with the top of the tire. On the rear right the top of the frame sits an inch or two below the top of the tire when in H position.
When I switch from H to N it takes a significant amount of time and the rear left often won't come back down. If I drive the vehicle around a bit (with the steering wheel cocked about an 1/8th of a turn counter clockwise to compensate for the elevated rear left) it eventually comes back down to the N position. Once back in N position the vehicle drives straight and true.
A couple of questions:
Any advice would be most appreciated.

A couple of questions:
- does this sound like a potential issue with the AHC sensor or something else?
- if it sounds like the sensor, is there a place to source oem sensors other than the dealer?
Any advice would be most appreciated.
