Use of leaf springs


The main purpose of leaf springs attached to rear axles of vehicles is to give support. These rear springs lessen the impact of potholes and bumps in the road, and hence ensuring a smooth ride. They are also effective in maintaining the alignment of the tires of the vehicle. Leaf springs are typically used in the following types of vehicles:
  • Commercial vehicles like vans, SUV’s and trucks.
  • In farming equipment for easy hauling and transportation of farm produce.
  • In construction vehicles for facilitating carriage of heavy items like concrete, stones and bricks.
Signs that may suggest the requirement for a new leaf spring

Due to the benefits provided by leaf springs, it is advisable to ensure that the vehicles are maintained regularly. This can help in early detection of leaf spring replacement requirement. For vehicles carrying heavy loads, ensuring that the installed leaf springs function efficiently is important.

Leaf springs are located on the rear or front end of the vehicle. They may be attached either to the top or bottom of the axle in SUV’s, vans, trucks and cars. One easy way to identify leaf springs is to look for narrow steel strips, which may be stacked together. This leaf spring design helps in providing support to the vehicle when additional weight is placed on it. New leaf springs are easy to identify as they are generally coated with black paint.

Few signs that can help identify the requirement for a new leaf spring include:

Look for cracks


It is advisable to opt for leaf spring replacements in case they lack certain pieces or have broken or cracked.

Swaying


Leaf springs ensure smooth rides by absorbing the energy generated when the vehicle rides on bumps and potholes. Swaying or bouncing of the vehicle on hitting a bump may signal the need for a leaf spring replacement.

Evaluate the ability of the vehicle to carry heavy loads


An easy way to ascertain whether the leaf spring is functioning efficiently or not is to add load on the vehicle. If the vehicle sags backwards from the load, then it is a sign that the leaf spring is unable to support the additional weight. In such situations, it is recommended to replace the leaf spring.

For increasing the existing load carrying capacity of the vehicle, an additional leaf spring may also be added to the already installed leaf stack. This can raise the vehicle’s height, in addition to increasing its capacity. These additional leaf springs are known are available as add a leaf kits.

For businesses using load carrying vehicles, ensuring proper functionality of the leaf springs is important. A damaged leaf spring may adversely affect the operating capacity of the vehicle.
