Service bulletins for the 2021 Ford Transit
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

| TSB 22-2444 | 2022-12-02. Service bulletin. UNKNOWN OR OTHER; POWER TRAIN:DRIVELINE:DRIVESHAFT; POWER TRAIN. This article supersedes TSB 22-2271 to update the vehicle model years affected. Some 2015-2023 Transit vehicles equipped with rear wheel drive (RWD), single rear wheel (only), and U-joints at the transmission flange and rear driveshaft may experience a boom/hum/moan noise from the rear while driving. This noise is most noticeable at highway speeds: 112-121 km/h (70-75 mph) for 4.10 axle ratio 121-128 km/h (75-80 mph) for 3.73 axle ratio 136-145 km/h (85-90 mph) for 3.31 axle ratio The noise may also be present to a lesser degree at roughly half of the noted speeds. This may be due to a 2nd order driveline frequency transmitted through the rear driveshaft, rear axle and into the body through the leaf springs. To correct the condition, follow the Service Procedure to install a driveshaft torsional damper. NOTE: The torsional damper will not resolve a vibration. |
