Automotive Repair Novice's Guide To Automobile Suspension Systems

If your car is having a problem with its suspension system, then it is important that you have a basic understanding of how automotive suspension systems work. This knowledge will help you speak with your mechanic about the problem, and it will help you to ensure that your car is properly repaired.

Here is some basic information to help you understand the purpose of your car's suspension system and some basic information about its various parts:

Purpose of the Automotive Suspension System

The suspension system in your car connects its wheels to the frame and the steering system.

The purpose of the suspension system in your car is to:

  • support the vehicle's weight
  • keep the correct vehicle height
  • keep tires in contact with the road
  • manage shock force reduction
  • maintain wheel alignment 

As you are driving down the road, your car needs to handle all of the forces that are generated during turns and variations in grade. The suspension system is designed to help compensate for these things. In addition, the suspension is responsible for keeping you comfortable by reducing the effects of bumps, road noises, and vibrations.

Parts of the Automotive Suspension System

All automotive suspension systems have the following parts:

  • axles
  • linkage
  • shocks
  • struts

The axles hold the wheels together, and the linkage allows the wheels to move on the axles. The linkage components are the parts which are adjusted when you have your car aligned each time you replace the tires. The purpose of the wheel alignment is to keep the car's wheels straight and prevent uneven tire wear.

Struts are a straight metal bar which is used for mounting shocks. The shocks are used to regulate the height of the car and to keep passengers comfortable. As you drive over uneven pavement, the shocks take the force so that the cabin of your car will ride smoothly.

Automobile shocks are cylindrical objects that are filled with hydraulic fluid. As your car hits a bump, the shocks compress the fluid to take the force instead of it being felt by the car's frame. This makes your car ride better for passengers, and it also prevents damage to your car.


Now that you have a better understanding of how your car's suspension system works, you can better understand what your local automotive mechanic is explaining to you about your car's problem.

If you have additional questions about your vehicle's suspension system, then you should take your car to a local mechanic for an inspection.
