Preliminary Inspection

WARNING: This page is about a different car, the 2005 Infiniti QX56. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Always adjust the alignment with the vehicle on a flat surface. Use CONSULT-II "EXHAUST SOLENOID" active test to release the air pressure from the rear load leveling air suspension system.
NOTE: If alignment is out of specification, inspect and replace any damaged or worn rear suspension parts before making any adjustments.
  1. Check and adjust the wheel alignment with the vehicle under unladen conditions. "Unladen conditions" means that the fuel, coolant, and lubricant are full; and that the spare tire, jack, hand tools and mats are in their designated positions.
  2. Check the tires for incorrect air pressure and excessive wear.
  3. Check the wheels for runout and damage. Refer to "INSPECTION ".
  4. Check the wheel bearing axial end play.
    1. Axial end play: 0 mm (0 in) 
  5. Check the shock absorbers. Refer to "SHOCK ABSORBER INSPECTION ".
  6. Check each mounting point of the suspension components for any excessive looseness or damage.
  7. Check each link, arm, and the rear suspension member for any damage.
  8. Check the vehicle height. Refer to "WHEELARCH HEIGHT (UNLADEN*1) ".
    • If vehicle height is not within +/- 10 mm (0.39 in) of the specification, perform the control unit initialization procedure. Refer to "INITIALIZATION PROCEDURE ".
