Which Parts Of Suspension Are Prone To Fail?

Suspension of a car is prone to jerks from bumps. But do you know which of the parts are prone to failure?

In automotive usage, the term suspension means all of the parts that connect the vehicle to the road. Every vehicle has a suspension that is designed to do 3 major things:

  • Supports the vehicle
  • Absorbs bumps and shocks
  • Allows vehicle to move in response to the steering

Modern suspensions are composed of hundreds of different parts, and vehicles vary in their suspension designs. However, every suspension is composed of certain major subsystems, some of which are prone to failure.

Wheels and tires

Tires are not considered to be a part of the suspension, but they’re arguably the most vital component of it. Tires wear over time, and are subject to cuts and punctures from impacts.


Every car and truck has some sort of mechanism to absorb large bumps, and this includes a form of spring, a metal part that bends in response to force. Springs can even break when a vehicle hits a very hard bump, or sag eventually after many years. Repairing springs including the entire suspension system can be made easier through a reputed mechanic in Lilydale.

Shock absorbers and struts

Shock absorbers dampen the motion of springs right after a bump, preventing the vehicle from bouncing excessively. Shocks and struts are filled with thick oil, and thus, it can leak over time causing them to fail.


All of the suspension systems include various rods and other connecting pieces that collectively keep the wheels in place. Most of these links are solid metal parts which rarely fail. Bu if the vehicle meets with an accident or major impact, links can create problems and damages. Sometimes linkages and associated bushings are sold together, and the failure of a bushing can require to replace the whole assembly.

Bushings, bearings, and joints

As most parts of a suspension is movable, various linkages are connected by flexible connections. These include bearings and bushings. These are connections that allow a small amount of twisting or sliding, often without the need of lubrication. However there are some joints which may need the requirement of lubrication. Use a lubricant such as grease to continue free flow of movement. Some of the bushings are made of rubber, which can become brittle or break over time.

Suspension problems are common in vehicular systems and thus, you must consider to maintain it on a monthly basis. Hire a reputed mechanic in Lilydale if you want to enhance your car’s longevity.
