Lubricating a Speedometer Cable: Why and How

As an essential part of a vehicle’s instrumentation, the speedometer plays a crucial role in providing accurate information about the speed at which the vehicle is traveling. However, over time, the speedometer cable can become subject to wear and tear, leading to inaccurate readings or, in some cases, a complete failure of the speedometer. In order to prevent such issues and ensure the smooth operation of the speedometer, regular lubrication of the speedometer cable is necessary.

Why lubricate the speedometer cable?

1. Reduces friction: The speedometer cable consists of a tightly wound metal core surrounded by a protective casing. Over time, this casing can wear out, leading to increased friction between the metal core and the casing. By lubricating the speedometer cable regularly, friction can be minimized, allowing the cable to rotate freely, resulting in accurate speedometer readings.

2. Increases lifespan: The continuous movement of the speedometer cable can cause it to become dry and prone to damage. By lubricating the cable at regular intervals, the lubricant ensures that the cable remains well-lubricated, reducing the risk of it becoming brittle or breaking.

3. Prevents corrosion: The speedometer cable is often exposed to various elements, such as water, dirt, and grime. Over time, these contaminants can cause the cable to corrode, leading to increased friction and potential speedometer failure. By lubricating the cable, a protective barrier is created, preventing moisture and other contaminants from coming into direct contact with the cable.

How to lubricate a speedometer cable:

Materials needed:

  • Speedometer cable lubricant (specifically designed for this purpose)
  • Rags or towels
  • Wrench or pliers (as required for cable removal)
  • Lube injector or grease gun (optional)

Step 1: Locate the speedometer cable

The speedometer cable is usually connected to the back of the speedometer by a threaded connection. In some cases, it may be necessary to remove the instrument cluster or other components to gain access to the cable. Consult the vehicle’s manual or seek professional assistance if needed.

Step 2: Disconnect the cable

Using a wrench or pliers, carefully loosen the threaded connection between the speedometer cable and the speedometer. Keep in mind that the cable may still be attached to other parts of the vehicle, such as the transmission. Take note of the cable’s routing to ease reinstallation later.

Step 3: Clean the cable

Before lubricating the speedometer cable, it is important to ensure that it is clean. Use a rag or towel to remove any dirt, grease, or debris from the cable’s surface. This will prevent the lubricant from mixing with contaminants and losing its effectiveness.

Step 4: Apply the lubricant

Using a designated speedometer cable lubricant, apply a small amount of lubricant to the cable. If available, a lube injector or grease gun can facilitate the process by allowing the lubricant to be injected directly into the cable. Ensure that the lubricant is evenly distributed along the entire length of the cable.

Step 5: Reconnect the cable

After the cable has been lubricated, reattach it to the speedometer and any other components it was connected to. Make sure to tighten all threaded connections securely but avoid overtightening, as this can damage the cable.

Step 6: Test the speedometer

Start the vehicle and carefully observe the speedometer. Ensure that it is functioning correctly and providing accurate readings. If any issues persist, it may be necessary to seek professional assistance to diagnose and resolve the problem.

Tips for maintaining a lubricated speedometer cable:

  • Regularly inspect the speedometer cable for signs of wear, such as frayed or damaged casing. Replace the cable if necessary.
  • Avoid using general-purpose lubricants, as they may not provide adequate protection for the speedometer cable.
  • If the speedometer cable is continuously experiencing issues despite regular lubrication, it may be indicative of a larger underlying problem. In such cases, consult a professional mechanic for further diagnosis and repair.
  • Refer to the vehicle’s manual or seek professional assistance if unsure about the proper lubrication procedure for a specific vehicle model.


Lubricating the speedometer cable is a simple yet crucial maintenance task that can significantly improve the accuracy and lifespan of a vehicle’s speedometer. By reducing friction, preventing corrosion, and ensuring the cable remains well-lubricated, the speedometer can function optimally and provide reliable readings. By following the steps outlined above and incorporating regular cable inspections, vehicle owners can prevent speedometer issues and enjoy a smooth driving experience.
