Rear axle
The rear axle is sprung, with a hypoid final drive. The main gear pinion rotates in tapered roller bearings. The rear axle is attached to the rear of the body base. The rear wheels are driven by articulated shafts. The rear axle pinion is mounted on two tapered roller bearings. The differential is made on two planetary gears mounted on one shaft.

Rear wheel drive
The drive of each wheel consists of two ball joints of equal angular velocities, since the angular movements of the cardan joints are insignificant, their wear is minimal.
