Removing the transfer case

When installing the transfer case, orient it so that the clutch housing pins align with the mounting holes in the transfer case housing.

Then we insert the through shaft of the transfer case into the splines of the semi-axle gear of the differential, and the drive shaft into the slots of the differential box, and in order for the splines of both shafts to coincide, we slightly turn the output and through shafts of the transfer case.

After the splines coincide, we send the transfer case all the way into the clutch housing, while the transfer case will be centered on the dowel sleeves pressed into the clutch housing flange.
