When the vehicle has been found to lean towards the passenger's side, replace the right rear road spring with part number NTC8572 Pink/Red/Yellow.
NOTE:
Starting at VIN SA119523, the rear road springs were changed from single to dual rate. If you are working on a vehicle beyond this VIN, you must change the left rear road spring back to the single rate spring ANR3477 Brown/Green when installing NTC8572 Pink/Red/Yellow. DO NOT FIT ANR4352 WITH ANY OTHER SPRING ON THE REAR AXLE.
