Certain vehicles may have a condition in which the transfer case bearing setting may be out of specification. This condition may cause a potential slow fluid leak from the transfer case area and with an increasing fluid leak over time. If the leak is not addressed, there would be a potential increase in noise and lead eventually to a loss of propulsion if the unit fails. Dealers will re-adjust the transfer case bearing setting.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10172659-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10172659-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10172659","components":[{"id":"equipment","name":"Equipment and accessories","parent":null},{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"CHEVROLET","model":"SILVERADO 4500","year_from":2019,"year_to":2019,"match":"base","vehicle_ids":["2019_chevrolet_silverado"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
