What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationCertain 2020-2024 Model Year Transit All-Wheel-Drive (AWD) Vehicles All-Wheel-Drive Module (AWDM) Software Update. Warranty part analysis and bench testing has shown that thrust bearing damage can occur as a result of repeated high-torque launches consistent with severe-duty package delivery applications. Over time, fatigue failure of the thrust bearing can create loose metal debris in the system and distribute it throughout the transfer case, damaging other internal components and affecting vehicle performance.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford 24B39 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the 24B39 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does 24B39 cover?
The manufacturer filed it against 5 model years: 2024 Ford Transit, 2023 Ford Transit, 2022 Ford Transit, 2021 Ford Transit, 2020 Ford Transit. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
