4) establish the tool 3139 on the driveshaft and tighten plastic nuts

Prevention

The white point on a back flange of the driveshaft should coincide with a black point on a flange of back differential at driveshaft installation. If these points are not visible, note mutual position of the driveshaft and a flange of back differential before driveshaft removal.


5) remove bolts of fastening of the driveshaft to a flange of a transmission and back differential
6) prop up the driveshaft and the tool 3139 and remove bolts of the central support
7) remove together the driveshaft and the tool 3139
