Volvo S90 Steering wheel does not respond properly Inspection at your home or office.

How this system works:

The steering system revolves around the front wheels. The front wheels also do the majority of the braking, and in the case of front-wheel drive and all-wheel drive vehicles, put the engine’s power to the ground. Key components include:

• Steering Wheel: Big or small, soft or hard, high-tech or bare metal, these are in every functioning vehicle and give the driver control of the vehicle.

• Steering Column: This is what brings the rotation of the steering wheel down into the dashboard and under the hood. Some are one-piece while others are multiple pieces connected with joints that allow them to function as if they were one single column.

• Pinion Gear: This is the gear that moves the steering rack that makes the wheels turn. On some older rear-wheel drive vehicles, the column first goes into a recirculating ball gearbox that dictates how much the rotation of the steering wheel affects the front wheels.

• Steering Rack: This is the component that moves from left to right and provides the force to turn the wheels. Some use hydraulic power to assist steering, while others use electric power.

• Steering Linkage: This is found on older vehicles and has a couple of different components. The steering linkage consists of inner and outer tie rod ends. If this is an older vehicle then there is another rod that is called a center link. This connects the tie rod ends to the steering gear.
