Some drivers of 2006-07 Toyota Land Cruiser models with adjustable suspensions may complain that the ride height on the truck is uneven side-to-side or front-to-rear. Toyota says one likely cause for the trouble is moisture or corrosion in the front and/or rear height sensors.
Installing new-design sensors that better seal out the elements is the remedy. Note that if the rear height sensor connector or harness shows signs of corrosion, installing a sub-wiring harness into the existing harness is required, as well.
Here are all the new parts you'll need to complete the fix:
- Front/Left height sensor — Part No. 89406-60012
- Front/Right height sensor — Part No. 89405-60012
- Rear height sensor — Part No. 89407-60010
- Sub-wiring harness — Part No. 82989-60030
