Steering Gear
WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
The EPAS gear is an assembly that consists of a PSCM, a motor, a steering shaft torque sensor and EPAS gear isolators, all of which are serviced as an assembly. The inner and outer tie rods and the steering gear bellows boots can be serviced separately from the steering gear.
- The EPAS gear uses a 12-volt reversible motor to control the steering effort.
- The steering shaft torque sensor is mounted near the input shaft of the EPAS gear and is used by the PSCM to determine how much force is being used to turn the steering wheel.
- The EPAS gear has one inner tie rod located at each end of the gear assembly.
- The EPAS gear has one outer tie rod located at each end of the gear assembly.
- The EPAS gear has one bellows boot located at each side of the EPAS gear assembly. Each boot is held in place with 2 boot clamps. The boots and clamps are available for service.
- The EPAS gear has isolators located at each attachment point of the gear. These isolators (2 rubber and 1 steel) aid in the reduction of NVH concerns.
