## NHTSA's summary

Concerns: Rear\-differential lock control unit Information: This is to inform you of a voluntary Workshop Campaign on the above\-mentioned vehicles. With the current data record for regulating the rear\-differential lock, there may be increased wear on the pinion shaft on the servo motor for the rear\-differential lock as a result of extreme driving over the service life of the vehicle. This can cause noises and can subsequently impair the function of the rear\-differential lock.
