Checks, in order
- Measure the leanOn level ground, measure from the ground to the fender lip at all four corners. Lexus's threshold is more than 20 mm (about 3/4 inch) difference left to right at the front. Write the numbers down before going to the dealer.easy $ · under about $50
- The spring bulletinL-SB-0015-21 Rev1 (2021–2022, superseding L-SB-0041-14) covers 2010–2023 GX 460: the fix is a new front left coil spring and an alignment, about 2.2 hours, under the 4 year/50,000 mile basic warranty. Out of warranty it is still a cheap fix relative to chasing KDSS. The bulletin's two revisions list the spring part number supersession in opposite directions, so let the dealer pull the current number.medium $$ · about $50 to $500
- KDSS after a liftThe KDSS hydraulic system needs its two valve screws opened during a lift install so the system can re-center, then closed. A lift done without that step leaves the truck leaning or the sway bars loaded. Owners fix it by jacking the truck, opening the screws two to three turns, settling the suspension, and closing them. This is community practice, not a factory procedure.medium $ · under about $50
- Rule out the rear air suspensionOn Premium and Luxury trims with rear air springs, a rear corner that sags overnight is the air system, not KDSS. See the air suspension symptom.easy $ · under about $50
