Technical background: The right and left hand front upper wishbone levers have been identified as the source of the chattering noise which is audible within the cabin particularly when driving on rough road surfaces or when braking. New specification brackets are now available, the latest specification brackets are wider which increases the distance between the upper wishbone and the bracket, the increased distance eliminates contact between the two components. The right and left hand side front upper wishbones brackets and upper wishbones must be replaced along with all applicable fixings.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2014/MC-10170295-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2014/MC-10170295-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10170295","components":[{"id":"suspension","name":"Suspension","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"BENTLEY","model":"MULSANNE","year_from":2011,"year_to":2014,"match":"exact","vehicle_ids":["2011_bentley_mulsanne","2012_bentley_mulsanne","2013_bentley_mulsanne","2014_bentley_mulsanne"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
