Some 2010-2023 Lexus GX460 (KDSS equipped) vehicles may exhibit a condition where the vehicle leans more than 20mm (0.79 inch) from left to right when viewed from the rear of the vehicle.
Before beginning the procedure, confirm that suspension components have not been modified and the vehicle is in OE configuration.
Perform the inspection on a level surface. The tires must be on the ground and the wheels must be facing straight ahead. The suspension must be fully loaded. Remove any items in/on the vehicle that place any unbalanced load on either side of the vehicle. The fuel tank must be full.
View the vehicle from the rear. If the vehicle is leaning to the right, measure the left and right heights. If the difference is more than 20mm (0.79 inch), replace the left front coil spring assembly. Re-measure the height difference to confirm.
