I would leave it alone. You can’t really tell that the driver’s side is higher than the passenger side.

 

Definitely higher ... but no Driver ? Put someone in the driver's seat and remeasure ... given probably 85++% of drivers are riding solo ...

 

if you jack up the rear on the low side and the front looks better, then you could consider to adjust the height sensor linkage and then readjust the headlight.
somewhat of a workaround and might not be ideal for some people.

 

I've had a 2014 gx premium (no KDSS) for a few years now, and it's always pulled a bit to the right on both local roads and highways. i understand that roads have a crown that can cause this to some extent for all cars but it has just seemed a bit more extreme for this car than others i've driven. could be just down to how tall the gx is, but i finally took some measurements today and wanted to see if others who know much more about these cars can tell me if these are normal.

i found a fairly level parking lot with a half tank of gas and put a 4 foot level on the rear bumper, which showed the driver's side of the car is a bit higher than the passenger side. went around and also measured the distance from the ground to the top of each wheel well and got about 1" higher on the driverside wheel wells than the passenger side (35.25" front driver, 36.5" rear driver, 34.25" front passenger, 35.5" rear passenger). so definitely seems like there is a lean to the right, which seems consistent with how the car drives.

i also figured the gas tank is on the drivers side, so just in case i went and filled up to make sure that wasn't causing any imbalance. the rear bumper definitely evened out a bit and the rear driver wheel well might have dropped a half inch (which i think makes sense, i think the tank is right there). but still the same imbalance in the front as far as i could tell.

do folks know if there's a normal tolerance for suspension heights between the two sides of the car? is 1" something that could cause a noticeable pull when driving?

 

Just for clarification “all” GX 460s have KDSS… you are probably thinking about the AVS/RAHC which is the adjustable shocks and rear air bags.

 

The lean and pull are two separate issues. Lexus states a max difference of 20mm left/right difference for the lean. If more than that then Lexus TSB L-SB-0015-21 provides a solution which is to replace the left front spring with a new p/n.

On the pull, it is most likely the front end alignment and there has been a lot of discussion here in the past on that topic. If you do replace the spring, the front end will need to be realigned anyway so you will take of both at the same time.
