L-SB-0023-202020-08-03. Service bulletin. TSB: SUPERSESSION NOTICE The information contained in this bulletin supersedes Service Bulletin Nos. ST004-01, SU001-08, and L-SB-0174-08. The aforementioned bulletins are obsolete, and any printed versions should be discarded. Be sure to review the entire content of this service bulletin before proceeding. This Service Bulletin provides best practice procedures for vehicle pulling complaint, diagnosis, and repair for 2002 ? 2021 model year Lexus vehicles. This information supplements Repair Manual procedures when the symptoms are: ?Vehicle Pulling: The vehicle moves to the right or left when the driver holds the steering wheel while driving straight ahead without exerting steering effort. ?Steering Wheel Off Center: The vehicle travels straight, but the steering wheel is not pointed straight ahead. The vehicle is not pulling. Before repairing a vehicle pulling to one side, it is necessary to clearly identify the cause of the pulling condition. Frequently, pulling to one side is diagnosed as a wheel alignment concern. However, the actual cause may be related to the lateral force generated by the tires, vehicle damage, road crown or worn components. Performing a wheel alignment when tire force is the cause could result in the wheel alignment being set at a value outside of specifications. This could then cause other problems such as uneven tire wear, etc. A customer may notice a pull to the left when in the left lanes of travel and notice a pull to the right or no pull when traveling in the right lanes of travel on the very same section of roadway. This road crown effect is environmental and cannot be corrected with suspension adjustments or any other wheel or tire modification discussed in this bulletin.
