Steering and suspension systems are important for safety and comfort


The steering and suspension systems of a vehicle are not only an essential component of the safety triangle of your wheel assembly, (namely the Tires, Brakes, and Suspension)but add considerably to the overall driving enjoyment of your vehicle.

Improvements related to increased strength and durability of elements and advances in tire design and construction have made substantial contributions to riding comfort and to safe driving in recent years.

Today, there are two basic types of steering systems:

1) Standard mechanical (reciprocating ball) steering: Standard mechanical steering uses a series of links and arms to ensure both wheels turn in the same direction at the same time. It has not changed much over the years, and its principles are quite simple

2) Rack and pinion steering. The standard mechanical steering can be either power-assisted or non-power. Rack and pinion is almost always power-assisted and combines the steering box and center link into one unit. The steering wheel, through the steering column, is directly connected to the rack except in some of the modern vehicles they are drive by wire an electrical motor is located on the rack and is sent signals from a sensor located in the steering column. Inside the steering rack is a pinion assembly that moves a toothed piston, which in turn moves the steering gear.

The essential functions of a vehicle’s suspension system:

Maintain correct vehicle ride height

  • Reduce the effect of shock forces
  • Maintain proper wheel alignment
  • Support vehicle weight
  • Keep the tires in contact with the road

However, for this to happen, all of the suspension components, both front, and rear, must be in good working condition.​
