Steering components Lada Granta, Kalina
Steering Lada Kalina / Granta VAZ-2190 cars with electric booster and tilt-adjustable steering column.
The steering wheel is mounted on the steering shaft splines and secured with a self-locking nut. On cars equipped with a driver's airbag instead of a lining in wheel the airbag module is installed.
The steering shaft is composite. It consists of an upper shaft and a countershaft. The upper shaft rotates in two bearings pressed into the steering column tube.
An ignition lock with an anti-theft device is installed on the upper part of the column pipe. The intermediate shaft is collapsible, has two cardan joints at the ends.
The steering column of the Lada Granta / Kalina is assembled with a geared motor and an electric power steering control unit. The efficiency of the electric booster depends on the speed of the vehicle.
The electric booster works only when the engine is running. The steering column brackets are attached to the body on four studs with self-locking nuts. The brackets are pivotally connected to the steering column tube.
The upper bracket is equipped with a steering column locking mechanism. By moving the locking lever to the lower position, you can change the angle of the steering column. When the lever is raised, the speaker locks in the selected position.
The steering gear Lada Kalina / Granta VAZ-2190 is a rack-and-pinion type, consists of a crankcase, a drive gear and a rack, which are in gearing. The mechanism is fixed to the bulkhead of the engine compartment with two brackets on rubber mounts.
When the steering wheel is turned, the rotation is transmitted through the upper and intermediate shafts of the steering column to the drive gear, which, turning, mixes the rack.
Bolted to the Lada Granta / Kalina steering rack steering rods, which consist of the actual rods, tips and adjusting sleeves. At the inner ends of the steering rods, there are lugs with rubber-metal bushings pressed into them.
Ball pins are installed in the outer ends of the rods, with which the steering rods are connected to the pivot arms of the front suspension struts. When moving the rack, the rods turn the front suspension struts.
The length of the steering rods can be changed by rotating the adjusting sleeves and thereby changing the toe-in of the front wheels. The bushings are secured from spontaneous rotation with tie bolts wrapped in the flanges of the steering rod ends.

Checking the steering Lada Granta / Kalina
We visually check the condition of the protective covers of the ends of the steering rods and the steering mechanism. Damaged covers (torn, cracked) must be replaced.
Make sure that the steering column lock lever is raised to the stop. Trying to move the steering wheel in a vertical plane, we check the reliability of the steering column attachment by the locking mechanism.
If steering column Lada Kalina / Granta VAZ-2190 moves, remove the steering column linings and tighten the nut of the steering column lock lever axis with a 13 mm wrench.
Trying to move the steering wheel along the axis of the steering shaft, we make sure that there is no steering wheel play on the splines of the shaft and shaft in the steering column.
To check the steering play, turn the steering wheel to the straight ahead position. We put a slotted screwdriver on the dashboard so that its blade is located next to the steering wheel rim (for reliability, it can be fixed with masking tape).
Turning the steering wheel to the right before the wheels start turning (choosing the backlash), and then to the left and guiding ourselves by the blade of a screwdriver, with chalk, pieces of wires or otherwise, mark these positions on the rim. Backlash should not exceed 5 "(or 18 mm) when measured from the outside of the rim.
Increased backlash indicates the need for troubleshooting. As a rule, first of all, in the steering of the Lada Granta / Kalina, the tips of the steering rods fail.
To check that there is no play in the ends of the steering rods, the assistant slightly shakes the steering wheel from side to side. We put our hand at the junction of the tie rod with the pivot arm of the suspension strut so that the palm touches them at the same time.
When a backlash appears in the tie rod tip, the pivot arm will feel displaced relative to the tie rod. We check the tightening of the nuts of the steering column universal joint bolts. We repeat the check on the other side of the car. Defective hinges are replaced.
When swinging the steering wheel from side to side, listen to the operation of the steering mechanism. A knock on the right side of the steering box indicates wear on the bearing bush. The defective steering gear is removed and repaired or replaced.
We turn on the ignition - on the instrument panel, the control lamp for the malfunction of the electric power steering should light up. We start the engine.
The control lamp should go out, the steering wheel should turn easily with one hand. If the lamp comes on while the engine is running, it indicates a malfunction of the electric amplifier and the need to repair it.

Make sure that when the steering wheel and the vehicle wheels are in a straight line, the steering wheel spoke is horizontal. Otherwise, determine the cause of the malfunction and eliminate it.
While turning the steering wheel from lock to lock, visually and audibly check the following:
— operation of the steering column adjustment mechanism. When the adjustment lever is lowered, the steering column should move up and down smoothly, without jerking or jamming, and when the lever is raised, it should be securely fixed in the installed position.
— lack of clearance in silent blocks (rubber-metal hinges), steering rod hinges, riveted and splined joints of the elastic coupling of the steering shaft;
— secure tightening of bolts 20 (see "The steering gear of the car Lada Kalina VAZ 1118") and stopping them with a plate 21 fastening the rods to the rail and the nuts of the hinge fingers of the outer ends 4 (see "Steering diagram of the car Lada Kalina VAZ 1118") steering rods;
— if there are any sticking or knocking sounds in the steering wheel that prevent the steering wheel from turning.
— condition of the right and left protective caps of the steering gear. The damaged cap must be replaced with a new one.
If knocks and sticks are found in the steering, disconnect the tie rods from the pivot arms of the telescopic suspension struts and recheck. After making sure that knocks and jams come from the steering, remove the steering from the vehicle, check the gap between the steering rack stop and the nut. If necessary, replace the worn steering parts and adjust the clearance between the stop and the nut. If the jamming and knocking have not stopped, the steering gear must be removed from the car and replaced.
Helpful advice:
Repair of the steering mechanism of the VAZ Lada Kalina 1118 is recommended to be carried out in a specialized center.
To check the backlash in the steering, set the front wheels and steering wheel to the position corresponding to the straight-line movement of the car.
Turn the steering wheel in both directions until the wheels start turning (while the wheels must remain stationary). The total backlash of the steering wheel of the VAZ Lada Kalina 1118 should not exceed 5 °(corresponds to turning the steering wheel by 15 mm), provided that the steering mechanism, steering rods, front wheel hub bearings and telescopic struts are in good working order. If necessary, replace the defective parts and tighten the loosened fasteners of the steering elements. The presence of knocking and backlash in the rubber-metal joints of the steering rods and the ball joints at the ends of the rods is not allowed.
