Mitsubishi Power Steering Assembly
The power steering assembly on your Mitsubishi has an input section, a section where work is done and finally an output section. If you know what components are present in your cars power steering system, itll be easier for you to understand how the system works.
The Input Section
Steering input is by way of the steering wheel. When you turn the wheel, a shaft in the steering column is also turned. This shaft is connected -- by way of a steering coupler/universal joint -- to the rack and pinion assembly, where your steering input is translated into side-to-side movement of the steering arms.
The Steering Rack
The power steering rack is where your steering input is translated into the side-to-side motion that turns the front wheels to turn the car. At the end of the steering column is the steering rack input shaft, which has a pinion gear at the end of it. As this gear rotates, it meshes with teeth on the steering rack, moving the rack in the required direction to turn the car.
The Output Section
The steering rack is coupled to the steering knuckle at each wheel by way of inner and outer tie rod ends, which allow for suspension travel and knuckle pivot.
Steering Assist
The addition of a hydraulic fluid is what adds the power to power steering. The pump sends fluid to the steering rack, where valves direct it in the proper direction to work against seals that help push and pull the rack when you turn the steering wheel.
