## NHTSA's summary

Complaint Noise from front end attributable to steering gear. Cause During diagnostics of a front end noise, workshop is under the impression the noise is coming from the steering gear. Remedy Workshop diagnostics point to the steering gear as the root cause of the noise and the below LI's have been ruled out. • LI46.35\-P\-067339 \- "Rattling or Humming Noise When Steering" • LI46.35\-P\-071461 \- "Check Tie Rod Outer Joint of Steering Gear" • LI46.10\-P\-077391 \- "Knocking Noise In The Area Of The Steering Gear or Steering Column Tube When Braking Or Moving Off; The Steering Wheel Can Also Be Felt To "Crack"" If the above has been completed and the noise is still present, please continue with the below: • Video underneath the vehicle with clearly audible noise. • Video inside the vehicle with clearly audible noise. • Vehicle checked for history of collisions. • List of other checked components \(suspension, drive line components, wheel bearings, etc...\). • Check integrity of dust boots and dust boot clamps. Ensure no water has entered into the steering rack. • Along with the audible noise, does the feel/noise change through only a certain part of the steering arc sweep? • If noise is described as a "clacking" noise when moving the steering wheel back and forth, please navigate to WIS and find and perform the document "Setting play between thrust element and steering rack". Provide both pre\-adjustment and post\-adjustment numbers. If the above is completed and no findings are noted, please open a TIPS case to the Body/Chassis/Entertainment inbox.
