Electronic Power Assist Steering (EPAS)
WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The Electronic Power Assist Steering (EPAS) consists of the following components:
- Steering gear
- Outer tie rod
- Inner tie rod
The rack and pinion steering gear that is used with the EPAS system is a manual (non-hydraulic) steering gear that is contained within a 1-piece die cast aluminum housing. The power assist is provided by a 12-volt motor (mounted to the gear housing), a belt and a pulley and bearing assembly that is connected to the steering rack. The steering gear and motor/module are serviced as an assembly. A new steering gear includes inner tie rods, however, the inner and outer tie rods can also be serviced separately.
