Dear customers, in order to avoid mistakes when sending the propeller shaft toLADA 4 x4 intermediate assembly, in the "Comment" line indicate the model of your car, year of manufacture.
Cars VAZ-21213 and VAZ-21214 are comfortable, high-speed, subcompact, all-wheel drive cars off-road, designed for the transportation of passengers and goods on roads with all types of surfaces and dirt roads. Cars combine high cross-country ability off-road vehicle with all driving wheels with the conveniences, comfort, dynamics and speed qualities of a modern passenger car.
Since the drive axles of the NIVA car are located below the transfer case, the axes of the drive shafts of the transfer case axles are located at an angle in relation to the axes of the main gears of the driving axles. This angle is constantly changing due to the elastic connection of the drive axles to the body. Not only the angle changes, but also the distance between transfer case and driving axles. Therefore, in the device cardan transmission elements are provided that ensure the transmission of torque at a constantly changing angle and changing length of the cardan transmission. These elements include cardan joints and splined joints.
Intermediate propeller shaft, connecting the gearbox to the transfer case, has an elastic coupling and a universal joint of equal angular velocities... The cardan shafts of the rear and front axles at the ends with cardan joints on needle bearings with grease fittings transmit torque from the transfer case to the main gears of the axles.

The cardan transmission consists of intermediate (pos. 7.8), front 4 and rear 10 driveshafts.
In the design of the intermediate shaft, an elastic coupling and a constant velocity joint are used. The elastic coupling reduces noise and vibration of the shaft and transfer case. The sleeve is made of six rubber elements 37, between which there are metal liners 35, to which the rubber elements are vulcanized. The liners have holes for bolts 33 connecting the elastic coupling to the gearbox output shaft flange and to the flange 34 of the elastic coupling. Washers 36 are located under the nuts of the fastening bolts for balancing the intermediate propeller shaft. The elastic coupling is centered on the flanges by six projections of the liners 35, of which three go into the slots of the gearbox output shaft flange, and the rest into the slots of the flange 34 of the elastic coupling.
The alignment of the gearbox output shaft and the intermediate propeller shaft is ensured by the centering ring 38 pressed onto the end of the gearbox output shaft and by the centering sleeve pressed into the flange 34.
The hinge of equal angular velocities of the intermediate shaft consists of a cage mounted on the slots of the flange 34 of the elastic coupling, a separator 32, in the holes of which six balls are located, and a housing 28, inside which six radial grooves are machined. The balls 29, located in the grooves of the body and the holder, pivotally connect them to each other. Hinge cavity filled with grease and sealed rubber cover 30, which, together with the protective casing 31, is fastened with a clamp 39 to the hinge body, and the arc with its end to the shank of the flange 34. From the end, the hinge cavity is closed with a plug 40.

The intermediate shaft transmits the torque from the transmission output shaft to the transfer case drive shaft. It consists of an elastic coupling, a flange and a constant velocity joint. The intermediate shaft is centered on the output shaft of the gearbox with a rubber bushing.
The elastic coupling allows the transmission of torque with minor changes in the angle between the shafts of the gearbox and transfer case, protects transmission parts from dynamic shocks and reduces noise and vibration of the cardan transmission during operation.
The elastic coupling consists of six steel liners connected by rubber bridges. Due to its elasticity, the clutch dampens jerks in the vehicle's transmission. The elastic coupling is attached to the output shaft flange with three bolts passed through the holes in the bushings. The other three holes are used to fasten the coupling to the flange on the intermediate shaft. Balancing washers are located under the bolt nuts. When disassembling, we mark their location so that later they can be installed in their original places. In order not to disturb the balance, we note the relative position of other parts of the intermediate shaft. A constant velocity hinge is put on the spline end of the flange of the elastic coupling. Its structure is similar to the external drive joint. front wheel... The hinge is secured against displacement by a retaining ring located in the groove on the flange shaft. The hinge is protected from dirt by a rubber bellows cover and a plastic plug in the rear end of the hinge housing. The cover is fixed on the flange shaft and the hinge body with special clamps with locks. A protective plastic cover is located under the large clamp (on the hinge housing).
On the first VAZ-2121 models, a cross was installed instead of a hinge of equal angular velocities.
Removing the intermediate shaft
Remove the transfer case assembly with intermediate shaft (see Removing the Transfer Case).
1. Keeping the shaft from turning with a screwdriver, with a key "13" unscrew the four nuts securing the intermediate shaft to the transfer case flange.
2. Remove the intermediate shaft. Install the intermediate shaft on the transfer case in reverse order.
3. Before installing the intermediate shaft assembly with the transfer case, we check the condition of the rubber centering sleeve located on the flange of the output shaft of the gearbox
