Removal
To remove the steering gear, disconnect the wires from the battery and remove the signal switch by carefully bending the three latches from below through the window with a screwdriver. Unscrew the steering wheel mounting nut 10 (Fig. 185) and remove it, then unscrew the screws, remove both halves 7 and 11 of the steering shaft trim cover.
Note: If it is necessary to remove only the steering gear housing, unscrew the bolt securing the lower end of the intermediate steering shaft to the worm shaft and the bolts securing the housing to the body side member.
Remove the instrument panel and disconnect the three-lever switch plugs from the wire harness plugs. Disconnect the wires from the ignition switch terminals and, after unscrewing the mounting screws and pressing the lock retainer, remove the ignition switch.
Loosen the clamp securing the turn signal, headlight and windshield wiper switch housing and remove it.
Unscrew the bolt securing the lower end of the intermediate shaft 3 to the steering gear worm shaft. Unscrew the bolts and nuts 12 securing the bracket 6 and remove the steering shaft with the bracket.
Loosen the nuts securing the ball joints of the side and middle rods to the pitman arm and use puller A.47035 (Fig. 186) to press the ball joints out of the pitman arm holes.
Remove the steering gear housing, having first unscrewed the bolts securing it to the body side member. Unscrew the screws securing the seal 2 (see fig. 185) and take it off.
Installation
Having secured seal 2 to the front shield, install the steering gear housing on the side member without fully tightening the housing mounting bolt nuts. Using a special device, orient the housing so that angle a (Fig. 187) does not exceed 32°, and the gap between the shaft and the brake pedal is at least 5 mm. Then fully tighten the housing mounting bolt nuts.
Set the steering knuckle to the middle position, for which align the marks on the crankcase and on the worm shaft (see fig. 184). Temporarily install the steering wheel on the shaft so that the spokes are horizontal, and in this position connect the cardan joint fork of the intermediate shaft to the worm shaft, then attach the steering shaft bracket to the body.
Remove the steering wheel and place the turn signal, headlight and windshield wiper switch onto the steering shaft.
Install the steering wheel on the shaft in its original position and, pressing the steering wheel as shown in Fig. 187, check for radial movement of the shaft. If there is radial movement, replace the upper shaft of the steering gear or its bearings. Check the smoothness and ease of rotation of the steering wheel in both directions, then tighten the steering wheel mounting nut and stake it at three points.
Slide the housing of the turn signal, headlight and windshield wiper switch towards the steering wheel until it stops and tighten the switch mounting clamp.
Connect the wires to the terminals of the ignition switch and secure the switch with screws to the steering shaft bracket. Connect the plugs of the turn signal switch, headlight switch and windshield wiper switch to the plugs of the wire harness.
Install the two halves of the trim cover onto the shaft and fasten them with screws. Install the horn switch onto the steering wheel.
Install the ball joints of the middle and left side tie rods on the steering knuckle and secure them with nuts. Then adjust the toe-in of the front wheels and check the force on the steering wheel, which should not exceed 20 kgf when turning the wheels on the spot on a smooth plate (when measuring on the wheel rim). With the steering wheel spokes horizontal, connect the worm shaft to the lower end of the intermediate steering shaft. Without fully tightening the steering shaft bracket mounting bolts, turn the steering wheel in both directions several times, and then tighten the bracket mounting bolts.
