What is a Drive Shaft? Understand Its Function and Symptoms of Damage
Talking about the components of a car's drivetrain can certainly confuse many. This is because there are several components that have names ending with "shaft." However, among all the components of the car's drivetrain, there is one important component known as the drive shaft. So what is the function of this component? And what are the signs that can indicate if this component is damaged? To answer these questions, let's take a look at the following discussion.
What is a Drive Shaft?
As previously explained, the drive shaft is one of the components of the drivetrain. Specifically in cars with FWD or AWD drivetrain systems. The drive shaft is also known in the automotive world by another term, namely the wheel shaft.
Function of the Drive Shaft
The drive shaft has various functions that can help the mechanism of the car's drivetrain work properly. The complete functions are as follows.
1. As a power distributor
The drive shaft has a primary function in the car, which is to distribute power from the transmission to the wheels. This occurs because one end of the drive shaft is connected to the car's wheels and the transmission.
2. Increases wheel flexibility
Next, the drive shaft can enhance the flexibility of the car's wheels. This allows the wheels to move freely at turning angles. As a result, the car can navigate various road terrains effectively.
3. Housing for ABS reluctor
In addition to the two functions above, the drive shaft also serves as a housing (mounting place) for the ABS reluctor. As is known, the ABS reluctor functions as an informant for the ABS sensor so that when the wheels rotate, the ABS sensor will identify the rotational speed of each wheel.
Signs and Symptoms of a Damaged Drive Shaft
When the drive shaft is damaged, several signs and symptoms may arise that you can feel. Here are the complete signs and symptoms.
1. Clicking sounds
When your car makes a clicking sound while turning, it indicates that the drive shaft is having issues. This sound can be heard in the front left or right wheel area of the car, depending on which part is damaged. This sound typically occurs due to an improper position of the drive shaft or a loose drive shaft.
2. Body vibrations at certain speeds
Symptoms of a damaged drive shaft can also be identified by vibrations that occur in the car's cabin. These vibrations will appear at certain speeds (when accelerating). The vibrations can be felt from the steering wheel to the car's body.
3. Unbalanced steering
A damaged drive shaft can also cause a unique phenomenon such as an unbalanced steering system. When the car is moving slowly, the steering will feel heavy on one side. This happens because a damaged drive shaft can disrupt the performance of the wheel shaft when it rotates. As a result, the rotation of the left and right wheels becomes less stable. This is what makes the car's steering feel like it is being pulled to one side. This condition certainly affects driving comfort and can endanger the driver's safety.
If these symptoms occur in your car, it is advisable to visit the nearest workshop to replace the drive shaft. Make sure to service at a Daihatsu workshop so that all issues regarding your car can be handled properly. This is because Daihatsu workshops have competent mechanics in their field, modern service equipment, and genuine spare parts.
