If the halfshaft is unavailable due to a part backorder situation, dealers can perform Technical Service Bulletin (TSB) 23-2114. The TSB Service Procedure uses a revised halfshaft and intermediate shaft, which eliminates the front axle disconnect actuator assembly and requires an all-wheel-drive (AWD) module software update. Unless the specific TSB criteria are met, TSB 23-2144 should not be performed if halfshaft part number L1MZ-3A427-G is available.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10239097-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10239097-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10239097","components":[{"id":"equipment","name":"Equipment and accessories","parent":null},{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"LINCOLN","model":"AVIATOR","year_from":2020,"year_to":2021,"match":"exact","vehicle_ids":["2020_lincoln_aviator","2021_lincoln_aviator"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
