I have a 2011 GS460 with 46,000 miles . While standing behind it in my garage, I notice what appeared to be a tilt of the frame to the left. I measured the height from the floor to the bottom of the wheel well (mid tire) at all four wheels. I did this in my garage and then took it to a parking lot that appeared to be level . The result was the right side, on both tires, is 1" higher than the left side on both tires. I did check the tire pressure on all four tires and they are inflated to the same pressure.

Any suggestions on what might be causing this ?

Thanks

 

You can check your spring coils to make sure one isnt broken. Jack up each corner of the car, and with a flashlight shine it on the spring coils and make sure the spring is seated in its rubber base, and that it is not broken or fatigued.

But many car engineers design cars to be uneven to compensate for gas, passengers, etc. Its common, to see 1/2-3/4

Also measuring from the ground to the fender is not as accurate as measuring from the fender to middle of the center cap wheel. For example you can have a worn tire on one side and thicker tread on the other. Measuring at the center of the cap to fender removes the tire thickness from the equation

 

Thanks for the info
