INSTALLATION SERVICE POINT
>A< WASHER/DRIVESHAFT NUT INSTALLATION
caution / Before securely tightening the driveshaft nuts, make sure there is no load on the wheel bearings. Otherwise the wheel bearings will be damaged.
/ 1. Be sure to install the driveshaft washer in the specified direction.
2. Using special tool MB990767, tighten the driveshaft nut. At this time, tighten the nut to the specified lower limit torque so that the pin hole may align with cotter pin.
Tightening torque: 196 - 255 N·m (145 - 188 ft-lb)
3. If the pin hole does not align with the pin, tighten the driveshaft nut [less than 255 N·m (188 ft-lb)] and find the nearest hole, then fit the cotter pin.
