Steering gear installation details on petrol models
6 - Steering knuckle; 8 - Steering mechanism; 15 - Hollow bolts of nipple connections; 16 - Steering shaft mounting bolt; 17 - Steering gear assembly mounting bolts
1. Using a suitable puller, press the transverse rod (9) out of the steering arm (7).
2. On models equipped with 113 series engines, remove the left headlight assembly (see Chapter On-board electrical equipment) and steering pump (see Section Removal and installation the steering pump).
3. Remove the radiator (see Chapter Cooling, heating, ventilation and air conditioning systems).
4. Remove the power steering fluid cooling line (14) (see Section Removal and installation of the power steering fluid cooling line).
5. Unscrew the hollow bolts (15) of the union connections and disconnect the hydraulic lines from the steering gear assembly - drain the hydraulic fluid into a previously prepared container.
6. Remove the bolt (16) and disconnect the lower universal joint of the steering shaft from the input shaft of the steering gear.
7. Unscrew the mounting bolts (17) and remove the steering gear assembly.
8. Installation is carried out in the reverse order. Do not forget to check the levels of working fluids and, if necessary, make the appropriate adjustments.
9. Finally, clear the memory of the on-board diagnostic system processor (see Chapter Engine electrical systems) and adjust the front wheel alignment angles (see Section Suspension Geometry).
