Steering System
Steering System
The mechanism that allows the driver to control the direction of the vehicle.
Steering Column
Steering Column
Connects the steering wheel to the steering gear, transferring steering input from the wheel to the front wheels.
Rack and Pinion Steering
Rack and Pinion Steering
A common type of steering system that converts the steering wheel's rotational motion into linear motion, which in turn moves the steering linkage.

Study Notes
Steering Fundamentals
- Steering systems precisely control wheel direction, maintaining correct steering, and transmitting road feel to the driver.
- Steering systems absorb road shock.
- Steering columns consist of steering wheel, shaft, column, ignition key mechanism, and sometimes a flexible coupling and universal joint.
Steering System Types: Rack and Pinion
- Most passenger vehicles use rack and pinion steering housed in one unit.
- Pinion gear meshes with a rack of gear teeth.
- The inside tire needs a sharper turn to follow a shorter radius.
Steering Angles
- The inside tire must make a sharper turn to follow a shorter radius.
Steering Linkage
- Primarily used on trucks, vans, and larger vehicles, but also on most passenger vehicles before 1980.
Ball Sockets
- Allow for motion in all directions between two connected parts.
- Some allow for lubrication with grease fittings and sealed units.
- Used in pitman arms, idler arms, and tie rods.
Power Steering
- Reduces driver steering effort.
- Many vehicles use hydraulic power steering, where an engine-driven pump uses fluid to assist the driver.
- More manufacturers are switching to electric power steering, using an electric motor to assist the driver.
Suspension Fundamentals
- Supports vehicle weight.
- Allows wheels to move up and down.
- Allows for rapid cornering without excessive body roll.
- Keeps tires in firm contact with the road.
- Prevents excessive body squat during acceleration or body dive during braking.
- Keeps wheels aligned for correct steering.
Shock Absorbers
- Convert kinetic energy into heat to dissipate.
- Reduce road shocks and vibrations, creating a smoother, more comfortable ride.
Steering Types
- Coil spring, leaf spring, torsion spring.
Spring Functions
- Support vehicle weight (sprung weight).
- Absorb road bumps.
Unsprung Weight
- Weight not supported by springs (tires, axles, wheel bearings).
Other Suspension Parts
- Control Arms: Connect steering knuckle to body, with bushings or ball joints.
- Steering Knuckle: Supports wheel bearings, connects to the steering system, enabling steering.
- Ball Joints: Allow for steering and suspension movements, lubricated with grease.
- Shock Absorbers: Limit spring movement for smoother ride; one end to frame/body, the other to axle or control arm.
Sway Bar/Stabilizer Bar
- Used to prevent excessive body lean during sharp turns.
- Made of spring steel, attached to lower control arms and frame.
- Twisting the bar counteracts body lean.
