Leaf springs are the best suspension technology for automobiles. From domestic to commercial vehicles, leaf springs contribute to the luxury and comfort of smooth transportation.
Leaf springs are one of the most significant applications that are likely to wear out due to the movement of several different components. These parts are constantly exposed to mud, water, and debris. Bumps and potholes push the dirt further into the spring which, it left uninspected can cause the bearings to dry out and crack. It is crucial that leaf springs are checked at regular intervals to clean them and identify if they need to be replaced. Cleaning the leaf springs will ensure that their structural integrity is maintained and they are subjected to less wear and tear.
In this article, we shall be guiding you with important information about how to maintain leaf springs from getting damaged and losing its ability to absorb shock.
CLEANING LEAF SPRINGS
The leaf spring is made from slender pieces of steel of varying lengths, stacked and bolted together. Clamps are used to secure and hold the springs. During suspension movement, the leaves press and rub against each other causing dust particles and debris to accumulate between the leaves.
The unwanted particles can be cleaned using a wire brush. Brush along the surface and around the edges. A good industrial degreaser can also be sprayed to clean off the sludge and prevent the crunching noise caused due to the rust. Finally, wipe it with a cloth. This will ensure good performance of the vehicle.
INSPECTING SPRINGS AND MOUNTINGS
The mountings must also be checked for potential damages and faults like corrosion on the chassis. In case of any crack or fractures, the leaves need to be replaced altogether. Welding or any kind of repair will not help.
TIGHTEN THE U-BOLT
U-bolts hold the axle of the spring in place. If the bolts are loose, it will subject the leaf springs to wear and tear. Re-tighten the U-bolts to prevent the automobile from further sagging.
REPLACING THE LEAVES
Individual leaves of an entire leaf spring might need to be replaced if any of the steel strips has lost its shape or is out of place. In this case, you would need to take the vehicle to an auto shop where an expert would be able to help re-bend the metal with the use of a hydraulic press.
FINAL TAKEAWAY
To ensure a comfortable ride and extent the lifespan of your vehicle’s suspension system, it is important to take care and maintain the leaf spring function. Remember to consult an auto mechanic in case of any repair or replacement.
