SA-051-252025-12-05. Service bulletin. STEERING; SUSPENSION; POWER TRAIN; WHEELS. Noise, Vibration, and Harshness (NVH) Diagnostic Guidelines Diagnostic Guidelines When diagnosing NVH concerns, it is essential to first classify the issue into one of three primary categories: Noise, Vibration, or Harshness. Many customer complaints may involve overlapping symptoms, such as both noise and vibration, so identifying the dominant characteristic is critical. Once the primary symptom is determined, follow the appropriate diagnostic path. For example, if a concern includes both noise and vibration but is related to vehicle speed, the vibration diagnostic path should be followed. When considering component replacement during the diagnostic process, it is best practice to start with the lowest cost or most accessible part unless diagnostic evidence clearly identifies a more expensive or complex component as the root cause. This approach helps minimize repair costs and avoids unnecessary part replacements. For example, a growling or bearing whine noise may be mistakenly attributed to internal components in the differential, transfer unit, or transmission, when the actual source is a wheel bearing. Misdiagnosis like this can lead to unnecessary repairs, added time and cost. To help prevent this, always follow the guidelines in the repair procedure.
06-002-252025-12-04. Service bulletin. STEERING. Some vehicles may exhibit a light resistance and/or an unusual noise when turning the steering wheel in either direction. This concern may be caused by insufficient lubrication between the worm wheel gear and worm shaft. To eliminate this concern, the amount of grease between the worm wheel gear and worm shaft was increased and the housing end cover shape was modified.

06-004-19-35912019-08-01. Service bulletin. STEERING. Some customers may find a piece of aluminum tape and/or black liquid on the driver side floor. The aluminum tape may have dropped from the bottom of the steering column and the black liquid is grease that has melted and dripped onto the floor. This concern is caused by the grease from the power steering motor seeping out and loosening the adhesive on the aluminum tape. Parking in the sun can create high interior temperatures which may melt the grease and loosen the adhesive. To eliminate this concern, a housing cover has been added to the affected area of the steering column.
