An assistant will be needed to complete the job.
Removal
1. Place the vehicle on an inspection pit or overpass (see "Preparing a car for maintenance and repair").
2. On a car with an injection system, remove the adsorber (see "Adsorber - checking the purge valve, removal and installation").
3. Unscrew the nut of the bolt securing the intermediate shaft of the steering gear to the gearbox shaft and remove the bolt (see "Steering shaft - removal and installation").
4. Disconnect the steering rods from the steering gear coupling arm (see "Steering rods - replacement").
5. Using a 19 mm socket wrench, unscrew the three nuts securing the gearbox to the left side member of the car, holding the bolts from turning with a wrench of the same size. Holding the gearbox, remove the bolts.

6. Remove the gearbox shaft from the intermediate shaft cardan joint fork.
7. Turn the reduction gear arm until it stops in the eye A of the reduction gear housing. This will make it easier to remove the reduction gear.

8. Turning, we take out the gearbox upwards.

Installation
1. Having set the steering wheel in the direction of straight-line movement, through the hole in the bulkhead of the engine compartment, insert the gearbox shaft into the fork of the cardan joint of the intermediate shaft, orienting the gearbox arm (see below p. 4).
2. Fasten the gearbox with bolts to the body side member.
3. If there are difficulties when connecting the shafts, then without connecting them, we fix the gearbox on the side member. Having removed the steering wheel (see "Steering wheel - removal and installation"), remove the steering gear shaft and install it by placing the eye of the cardan joint of the intermediate shaft on the splines of the gearbox shaft (see "Steering shaft - removal and installation").
4. Orient the steering knuckle so that the line drawn through the centers of the knuckle holes is located at a distance of 27.5 mm from the gearbox mounting plane (average position of the gear roller). We set the steering wheel to the straight-ahead position.

5. Connect the steering rods to the steering knuckle.
6. After installing the new steering gear reducer, fill its crankcase with oil (see "Steering gear reducer - checking oil level").
