Different types of cars have different types of suspensions. Most car owners have heard of the term "pillars", but they may not know what the pillars on the car are or what they do.
The most straightforward definition is that the strut is the structural component of most modern independent suspension systems and serves as the connection point between the wheel and the body. They are mounted on the top of the chassis at the front end of most front-wheel drive vehicles. However, the strut is not limited to a front-wheel drive configuration. The main purpose of the pillar is to support the weight of the vehicle while absorbing surface shocks and ensuring smooth driving.
The pillar assembly is composed of two main elements: coil springs, which support the height, weight and stability of the vehicle; shock absorbers can absorb bumps and suppress vibrations caused by irregular roads.
Other components of the strut geometry include spring seats, strut bearings, and knuckles. Pillars are usually installed with the front wheels, but depending on the vehicle's settings and transmission system, they can also be installed on the rear wheels. Just as there are different types of cars, there are also different types of pillars. The most widely used design by automakers is called a MacPherson strut, which uses the top of a telescopic shock absorber as the upper steering pivot. MacPherson struts are used as shock absorbers, but are also designed to handle large lateral loads, such as when the vehicle is turning. Other common pillar designs include shock-absorbing pillars and air pillars. You can easily compare cars to determine which models have each type of pillar.
"Impact" and "pillar" are terms that are often used together or interchangeably, but this can cause confusion. There are major differences between these two components. Shock absorbers themselves have one main function-to absorb the bumps of each wheel-but they are not essential in the operation of a car or truck. On the other hand, pillars have multiple functions (including shock absorption), which are essential for vehicle operation. The pillar allows control and maneuverability of the vehicle.
When the pillars are working properly, they will minimize the bounce that the vehicle may suffer during normal driving. Therefore, the occupants will experience a smoother and smoother riding experience without most unwanted vibrations and vibrations. Pillars are important to the operation of the entire vehicle because they are an integral part of the suspension and steering system. In addition to general ride quality and load-bearing support, they also affect braking performance, wheel alignment and steering capabilities.
Some vehicles use strut towers, which are rigid rods mounted on top of the chassis to increase the rigidity of the vehicle. This enhancement will enhance the overall power of the vehicle, especially through high-speed maneuvers and cornering.
Ensuring that your pillars are in good working condition requires regular inspections by authorized technicians. Many repair shops and workshops provide this service and tire and brake inspections free of charge. For those living in climates with high precipitation, it is very important to conduct special rust and corrosion inspections on the pillars. It is recommended to replace ordinary pillars between 60,000 and 80,000 miles, but if your vehicle often carries heavy loads or drives on unpaved roads, you should replace it as soon as possible. These conditions can cause the struts to wear faster.
In addition to mileage and difficulty of use, there are many indicators that indicate that your pillars may need to be replaced. These include any of the following symptoms: overall bad riding, obvious vibration after riding bumps, slow steering or unresponsiveness, sudden wear of tire treads, wheel shaking when braking, shaking or excessive body roll when turning, or any signs The hydraulic oil under the tire well is leaking.
A simple test that a car owner can perform is to push the car hood down by hand to see if it will immediately pick up and stabilize. If it swings more than two times before stabilizing, the pillar may not function in the best way.
If the pillar needs to be replaced, the cost of parts and labor is usually between 750-800 US dollars. Most technicians can complete the replacement within two to three hours. Whether it is replaced by a professional or completed by the owner, a well-functioning pillar is still essential for the normal operation, performance and safety of the vehicle.
