2023-2024 Jeep Wrangler / Gladiator Front End Noise TSB

Owners of certain 2023-2024 Jeep Wrangler and Gladiator vehicles may experience a noticeable "Noise (rattle/thump/clunk noise) coming from the front end of the vehicle." This issue is detailed in Technical Service Bulletin (TSB) 02-005-24 REV. B, which supersedes TSB 02-005-24 REV. A. This bulletin, also released as Rapid Service Update (RSU) 24-077, identifies a manufacturing issue with the Active Stabilizer Bar System (ASBS) as the root cause of the Jeep Wrangler front end noise.

Symptoms

Customers may observe or hear a distinct "Noise (rattle/thump/clunk noise) coming from the front end of the vehicle." This Jeep Wrangler front end noise typically manifests while driving and indicates a potential problem with the front suspension components.

Diagnosis and Trigger Conditions

To diagnose the front end noise, technicians should first verify if the vehicle's VIN is included in the applicable RSU VIN list using VIP or a VIN search in DealerCONNECT/Service Library. If the VIN is on the list, the repair procedure should be followed. If a vehicle not on the RSU VIN list exhibits the symptom, the repair procedure can still be performed.

The core of the diagnosis involves inspecting the Julian date code located on the Active Stabilizer Bar System (ASBS) label. This date code helps determine if the component is from the affected manufacturing batch.

Repair Procedure Summary

The repair process outlined in TSB 02-005-24 REV. B involves a precise inspection and, if necessary, replacement of the Active Stabilizer Bar System (ASBS). Here's a summary of the steps:

1. Vehicle Preparation: The vehicle must be raised and properly supported. Technicians should refer to the detailed service procedures available in DealerCONNECT/Service Library under "Service Info > 04 - Vehicle Quick Reference / Hoisting / Standard Procedure."
2. Julian Date Inspection: The Julian date on the ASBS label (as shown in Fig. 1 of the TSB) must be inspected. This date is crucial for determining if the ASBS is part of the affected production run.
3. Replacement Decision:
   • If the Julian date is 165 or lower, the ASBS requires replacement. Technicians will then follow the detailed removal and installation procedures in DealerCONNECT/Service Library under "Service Info > 02 - Front Suspension / Front / Stabilizer Bar / Removal and Installation."
   • If the Julian date is higher than 165, the ASBS does not need replacement, and the inspection Labor Operation 02-20-01-94 should be used to close the active RSU.

Specific labor operations are provided for inspection (02-20-01-94, 0.2 hours) and for inspection and replacement (02-20-01-95, 0.7 hours). Additional labor operations for 12-Volt Battery Disconnect/Connect - PHEV (08-00-01-51) and Skid Plate Equipped (13-30-01-69) are also listed, indicating potential additional time for certain vehicle configurations.
