Bulletin Summary
All of the affected vehicles were built with front spring and front gross axle weight rating (FGAWR) below the customer expected value. The marketing Order Guide stated that on units equipped with Ambulance & Wrecker packages, customers would get up to 7000 lb front spring FGAWR. The front coil springs were built to match the FGAWR labels on these units. The customer did not receive the front coil spring capability they were expecting based on the data in the marketing Order Guide and their reserve capacity might be lower than expected.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
