How Does Suspension Work?

Suspension helps to give a comfy drive without breaching handling while it increases the friction between your tires and the road during acceleration and braking.

The suspension helps absorb shocks caused by bumps and potholes on the tires assists in absorbing shocks caused on wheels by potholes and bumps without passing vibrations to the car’s frame and its passengers.

The suspension also gives stability to the vehicle when cornering.

What Causes Suspension Squeak

Lack of lubrication is the common reason that causes your suspension to squeak.

The suspension has one rubber and two metals, and when they lack lubrication, it results in squeaking. When you have squeaky suspension, you are likely to experience a noisy drive.

If your suspension has grease installations on the ball joints, swing bar end linkages and steering linkages and pump them with grease, and it will help stop the squeaking.

Another cause of the squeak is rubber isolators in the middle of the top of coil spring tops and spring cubs of the car.

To stop squeaking here, apply grease on the strings and heaps and drop them on the sides of the isolators.

It will help prevent the squeaking, and if it does not stop, it might be they are worn out, and you should replace them.
