LX570 Lean (8 Viewers)

[Bob Frame]

My 2018 LX570 is doing a noticeable lean.

In both the Low and Normal suspension settings (didn't test the High setting) the driver's side (front and back) are lower than the passenger side. I took measurements from the floor to the top of the wheel wells at all four corners and found that the difference between the sides is 5/8"-1" on the Low setting and 1/2"-3/4" on the Normal setting. The vehicle seems to drive normally. It has been doing this lean since I acquired it in early 2019.

A call to my Lexus dealer service department produced no information other than "The GX is also this way, but we don't have any information of the LX" and "Fill your gas tank and see if that levels it out". Apparently the gas tank sits off center towards the passenger side???

I have searched for this on the forum and find a number of posts regarding this, but no real answers. And many of the threads are several years old.

Thought I'd see if anyone else is aware of this and if there's any clarity around what can be done to level the vehicle.

Many thanks for helping out here.

Don't waste your time trying to get it exactly level. You WILL go insane. ...Ask me how I know?

Even if you do get it level, it will vary from day to day depending on conditions. I've found it will vary 1/2" to 3/4" no matter what you do and chances are, you are the only one who notices. Even then, on the rare occasions you do get it level, your mind will play tricks on you and it will look like it's leaning.

Yeah I also chased a sag in front left and eventually decided it wasn’t material. One other mudder had it in to dealer over several trips and got an ahc computer replacement. Obviously done under warranty no reason to go out of pocket for it, cosmetic fix only.

So, the AHC computer was "allowing" the lean/sag to occur?

It was fixed with a new computer. Not clear what the issue was (if any) with the computer.

Wouldn't worry about it. Chances are the pavement you measured it on isn't exactly the most flat and ahc is compensating for it.

I would think if you have the same lean numbers consistently that you could dial it in a bit by adjusting the height control sensors on the driver or passenger side accordingly. Would get it pretty close.

Thanks razzyrazz.

Can you elaborate a bit on this? Is this something the dealer can do?

There are sensors located on each corner of the car, they have a small lever, and an adjustment bracket. The front sensors are on the "arms" of the UCA. You can see them and adjust them without removing anything. Loosen the small nut, and slide the lever in the adjustment bracket up. Retighten the nut. With this method you can get about an inch of lift per corner. It is not possible to make a high corner low in this method (Unless someone else put the arm up).

Note that the rear sensors go "down" to go up.

Here this is called a 'sensor lift' and people do it for cosmetics with new tires, or to clear minor rubs with larger diameters.

Brilliant! Thank you.

LX570 AHC height modifications (lift it!)

Ive been searching around and have read mention of people adjusting the AHC to set the truck height higher but I haven't seen any tutorial about it. I looked under the truck at the sensors and it looks like there is room for adjustment. I am really just hoping to raise the front end to remove...
