Mechanical
Mechanical steering wheel movements are transferred to the wheels via the steering column (1), steering shaft (2), steering gear (6) and tie rods (5). The wheel deflection is limited by a stop in the steering gear.
Hydraulics
The steering system is electro-hydraulic and is servo operated. The electric power steering module (EPS) (11), pump motor (10), oil reservoir (8) and servo pump (7) constitute a single unit.
The steering gear is of the rack and pinion type and grease lubricated.
It is installed with two screws in the sub-frame.
The total oil volume in the steering system is 1.2 liters.
The oil level is checked with the aid of the filling container (8).
The outer seal (4) is secured with catches in the steering gear pinion housing. The inner seal (3) is secured with plastic mounting elements against the cowl panel from inside the passenger compartment. The seals prevent sound from the engine compartment being transferred into the passenger compartment. They also seal against water, dirt and fire.
The heat shield (9) is secured to the steering gear housing using three screws. It protects the steering gear from heat radiation from the three-way catalytic converter (TWC), exhaust pipe and turbocharger (TC).
