Certain Kenworth vehicles from model year 2025 may contain steering gear(s) with a sector shaft that may not meet hardness requirements for the gear teeth due to improper heat-treating during assembly. Sector shaft gear teeth with lower than required hardness may prematurely wear, crack, or fracture. A fractured gear tooth may interfere with the gear mechanism leading to binding which in turn may increase the likelihood of a crash.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-11005552-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-11005552-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11005552","components":[{"id":"steering","name":"Steering","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"KENWORTH","model":"T280","year_from":2025,"year_to":2025,"match":"exact","vehicle_ids":["2025_kenworth_t280"]},{"make":"KENWORTH","model":"T380","year_from":2025,"year_to":2025,"match":"exact","vehicle_ids":["2025_kenworth_t380"]},{"make":"KENWORTH","model":"T480","year_from":2025,"year_to":2025,"match":"exact","vehicle_ids":["2025_kenworth_t480"]},{"make":"KENWORTH","model":"T680","year_from":2025,"year_to":2025,"match":"exact","vehicle_ids":["2025_kenworth_t680"]},{"make":"KENWORTH","model":"T880","year_from":2025,"year_to":2025,"match":"exact","vehicle_ids":["2025_kenworth_t880"]},{"make":"KENWORTH","model":"W990","year_from":2025,"year_to":2025,"match":"exact","vehicle_ids":["2025_kenworth_w990"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
