NOTE: The noise could occur at different steering wheel angles or power levels. Due to the insulating properties of the suspension and chassis, it can be difficult to determine which driveshaft is at fault by listening from inside the vehicle. See the attached video for an example of an outer CV joint clicking. These noises may be caused by the outer ball joint cage machining being out of specification. To eliminate this concern, tighter quality controls have been implemented to ensure proper machining of the cage window. NOTE: The part number for the improved part has not been changed. The current parts inventory is after the countermeasure production date implementation.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11034844-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11034844-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11034844","components":[{"id":"suspension","name":"Suspension","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MAZDA","model":"CX-30","year_from":2024,"year_to":2026,"match":"exact","vehicle_ids":["2024_mazda_cx-30","2025_mazda_cx-30","2026_mazda_cx-30"]},{"make":"MAZDA","model":"CX-50","year_from":2024,"year_to":2026,"match":"exact","vehicle_ids":["2024_mazda_cx-50","2025_mazda_cx-50","2026_mazda_cx-50"]},{"make":"MAZDA","model":"CX-50 HYBRID","year_from":2025,"year_to":2026,"match":"base","vehicle_ids":["2025_mazda_cx-50","2026_mazda_cx-50"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
