# Service bulletin TSB 24\-2104

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.

## Other bulletins for the same vehicles and component

- [TSB 26\-2380](/bulletins/11037537.md), 2026-09-29, Service bulletin: SUSPENSION; ELECTRICAL SYSTEM; STRUCTURE:BODY; UNKNOWN OR OTHER. This article supersedes TSB 25\-2575 to update the Parts list to add the applicable body wiring harnesses and underbody shield bolts. Some vehicles listed in the Model statement above may exhibit a "Sta\-bar Disconnect Service Required" message in the instrument panel cluster \(IPC\) with any of the following diagnostic trouble codes \(DTCs\) stored in the chassis control module \(CHCM\): C103A, C1A99, C1B03, C1B07, C1B14 and/or B1A67. This may be due to water intrusion in the stabilizer bar wiring harness connector.
- [TSB 25\-2613](/bulletins/11027609.md), 2026-01-13, Service bulletin: SUSPENSION; UNKNOWN OR OTHER. This article supersedes TSB 24\-2408 to update the parts list. Some of the vehicles listed in the Model statement above may exhibit a loud front end clink/clunk noise that leads to the identification of a cracked or broken front differential frame mount bracket. This may be due to flexing of the front differential from driving in 4L for extended periods of time. Note: Advise the customer that 4L/Rock Crawl drive mode should only be used when necessary, as using 4L when not necessary can cause damage to the vehicle. Refer to the Owner's Manual for additional information.
- [TSB 25\-2575](/bulletins/11025876.md), 2025-12-02, Service bulletin: SUSPENSION; ELECTRICAL SYSTEM. This article supersedes TSB 24\-2104 to update the vehicle model years affected. Some vehicles listed in the Model statement above may exhibit a "Sta\-bar Disconnect Service Required" message in the instrument panel cluster \(IPC\) and an illuminated warning light with any of the following diagnostic trouble codes \(DTCs\) stored in the chassis control module \(CHCM\): C103A, C1A99, C1B03, C1B07, C1B14 and/or B1A67. This may be due to water intrusion in the stabilizer bar wiring harness connector.
- [SSM 53869](/bulletins/11019478.md), 2025-06-11, Service bulletin: SUSPENSION; WHEELS. Some 2021\-2024 Bronco vehicles built on or before 01\-Jan\-2025 equipped with a 2.3L EcoBoost engine and 10R60 automatic transmission may exhibit diagnostic trouble codes \(DTCs\) P0300, P0301, P0302, P0303, and P0304 and may be accompanied by a buck/jerk sensation while driving between 35\-55 mph \(56\-89 km/h\) in gears 7\-10. If the condition remains after normal engine misfire diagnostics and associated repairs have been performed, the condition may be related to driveline torsional vibration induced by the rear wheels and/or rear axle assembly. The driveline torsional harmonics/vibrations are incorrectly identified by the misfire monitor as an engine misfire. Perform standard road force wheel balancing of all four tire and wheel assemblies and retest. If the condition continues to occur, replace the ring and pinion gearset in the rear axle. For claiming, use causal part 4209 and applicable labor operations found in Section 04 of the Service Labor Time Standards \(SLTS\) Manual.
- [SSM 51863](/bulletins/10241594.md), 2023-09-02, Service bulletin: SUSPENSION:FRONT:STABILIZER BAR; ELECTRICAL SYSTEM; ELECTRONIC STABILITY CONTROL \(ESC\). During replacement of the electronic front stabilizer bar disconnect assembly on 2021\-2023 Bronco vehicles, removal and replacement of the sta\-bar harness is required. To assist engineering with root cause analysis of failed sta\-bar disconnect assemblies, include the sta\-bar harness with the part in the same package when returning warranty replacement sta\-bar disconnect assembly. The sta\-bar disconnect assembly return should also be packaged in the original box with all protective insulators in place to properly protect it during shipping. Use the Report a Vehicle Concern link at the bottom of OASIS to submit a report with photos attached \(if possible\) for any front stabilizer bar disconnect concerns.
