Daimler Truck Arocs 964 recalls

Through a self-disclosure by the supplier ZF Friedrichshafen AG Daimler Truck AG was informed that there may have been a manufacturing deviation in vehicles of the models Atego 967 Actros 963 Arocs 964 and eActros 983 on the ball joints that are installed in steering components (e. g. drag links steering links tie rods). It cannot be ruled out that individual components did not fully undergo the prescribed hardening process and have therefore gotten into vehicles with insufficient material hardness. This may result in increased wear and in later phases reduced fatigue strength to the point of a possible fatigue fracture which would probably occur at low speeds with high steering forces (e.g. when maneuvering). In the event of such a fracture vehicle can no longer be steered and there would be a risk of accident.

Fix: As part of our planned recall campaign and as a precautionary measure we want to check whether insufficiently hardened components were installed in the potentially affected vehicles. Insufficiently hardened components will be replaced as part of the check.

Actros 963 and Arocs 964 models depending on the model designation up to two screws per installed axle bearing bracket may be missing. The axle bearing bracket guides the rear axle in the longitudinal direction of the vehicle. Spontaneous failure of the threaded connection can be ruled out. According to the Development department’s assessment loosening of the installed screws is possible at the earliest after approx. 600000 km.

Fix: As part of the recall action it must be checked whether all specified threaded connections are present on the axle bearing brackets on the potentially affected vehicles. If not the missing threaded connections must be retrofitted and tightened to the specified torque.
