Wide-based tires include any series tires with widths of 385 mm or higher. This is due a lack of friction in the current axle rotating components. Replacing the thrust roller bearing with a thrust washer assembly creates enough friction to eliminate the shimmy.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10182207-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10182207-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10182207","components":[{"id":"steering","name":"Steering","parent":null},{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"KENWORTH","model":"T880","year_from":2018,"year_to":2021,"match":"exact","vehicle_ids":["2018_kenworth_t880","2019_kenworth_t880","2020_kenworth_t880","2021_kenworth_t880"]},{"make":"KENWORTH","model":"W990","year_from":2019,"year_to":2021,"match":"exact","vehicle_ids":["2019_kenworth_w990","2020_kenworth_w990","2021_kenworth_w990"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
