Beam 15 of the front suspension - stamped, I-section, connected to the steering knuckles using pivots
The pivots have a flat in the center and are locked in the holes of the beam with wedge pins.
Vertical loads from the steering knuckles are transferred to the beam by ball thrust bearings, protected from dirt and dust by protective rubber-metal caps.
In the upper bosses of the steering knuckles, on the side of the beam, annular grooves are made, in which sealing rubber rings are installed, protecting the friction surfaces of the bushings and pivots from dust and dirt.
The pivot holes in the bosses of the steering knuckles are closed with covers with gaskets.
To lubricate the pivot bushings, grease fittings are installed in the center of the covers.
The thrust bearings of the kingpins are lubricated at the same time as the lubrication of the lower bushings.
There are special grooves in the bushings of the steering knuckles for the passage of lubricant.
The steering knuckles consist of two parts - a flange and a trunnion pressed into it.
The front wheel hubs with brake discs are mounted on trunnions on two conical bearings.
The steering trapezoid is located behind the front axle beam.
The trapezoid arms are attached to the steering knuckles with high strength bolts.
To exclude the possibility of loosening the bolts in operation, the threaded parts of the joints during assembly are coated with Unigerm-6 sealant TU 6-01-1285-84.
The angle of rotation of the steered wheels is limited by bolts screwed into the flange of the steering knuckles.

Longitudinal steering rod 14 - solid forged, transverse 6 - tubular, with threaded tips.
The threaded ends 7 have a different thread direction, which allows you to adjust the toe-in without removing the tie rod from the car.
The hinges of the longitudinal and transverse rods (Fig. 2) are unified among themselves.
Hinges are non-separable and do not require maintenance in operation.
