From a technical point of view, the wheel bolt tightening torques no longer need to be rechecked on the above mentioned models prior to delivering new vehicles to the customer.
In the meantime, all the plants conduct a multiphase tightening or alternatively a single tightening procedure with retightening by hand. This tightening procedure means that the settling process is completed so that the bolted assembly or the bolt preload force remain constant. As a consequence any need to retighten is no longer given.
Please note the new WU flat rates in the operation texts, standard texts, flat rates and work units.
The forms (OF) affected by this change have been accordingly adapted.
