Service bulletin LI35.30-P-078692

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Complaint: Cracking noises on load change from rear axle (can be heard from wheel side). Cause: Unfavorable manufacturing tolerances in the production process of the drive shaft. Remedy: If the above-mentioned customer complaint is present, a test drive and thorough NVH diagnosis must be performed in order to verify the root cause of the noise. If the axle shafts have been identified as the source of the noise, determine the vehicle production date and perform the following steps: (Date format > MM/DD/YYYY) Vehicles up to production date 12/09/2024: Replace both rear axles with A 214 350 44 06 Vehicles as of production date 12/10/2024: Do not replace any parts (wheel bearing, axle shaft) as it will not resolve the concern. A 214 350 44 06 must not be replaced. If rear axle shafts A214 350 44 06 are already installed and the noise is still present, please submit a TIPS case to the Powertrain inbox with the following information: - Initial Quick Test w/ Freeze Frame Data - Video or Sound file of the noise concern with details of where the recording was taken (ex. inside/outside vehicle, where sensors were placed) - Clear photos of part labels on both rear axle shafts - If possible, breakaway torque when loosening the axle bolt - Clear photos of the mating surfaces of rear axle shafts and wheel bearings
