What Are Car Jack Points?

by

Car jack points are specific areas on a vehicle’s frame or body that are designated for lifting the vehicle using a car jack. These points are reinforced to support the weight of the car safely and to prevent damage to the vehicle’s body or undercarriage during the lifting process. Knowing where these jack points are and how to use them correctly is essential for safely performing maintenance tasks like changing a tire, inspecting the undercarriage, or performing repairs.

Importance of Using Proper Car Jack Points

Using the correct jack points is crucial for several reasons:

  1. Safety: Proper jack points are designed to bear the weight of the vehicle. Lifting the car from the wrong spot can cause the jack to slip, leading to accidents or injuries.
  2. Vehicle Integrity: Incorrectly lifting the car can damage the vehicle’s frame, body panels, or undercarriage components. This can lead to costly repairs.
  3. Stability: Jack points provide a stable base for lifting. Using these points ensures that the car remains stable while lifted, reducing the risk of it tipping over.

Locating Jack Points

The location of jack points can vary depending on the make and model of the vehicle. Typically, they are found in the following areas:

  1. Front Jack Points:
    • Behind the Front Wheels: Often located on the car’s frame or subframe, behind the front wheels. These points are reinforced to handle the vehicle’s weight.
    • Crossmember: Some vehicles have a central jack point on the front crossmember, allowing you to lift the entire front end of the car at once.
  2. Rear Jack Points:
    • In Front of the Rear Wheels: Similar to the front jack points, these are typically located on the frame or subframe, just ahead of the rear wheels.
    • Differential: For some rear-wheel-drive vehicles, the differential can be used as a central rear jack point.
  3. Side Jack Points:
    • Pinch Welds: Many vehicles have pinch welds along the sides, under the doors. These are often used with scissor jacks, like those provided with a spare tire kit.
    • Rocker Panels: Reinforced sections of the rocker panels may also serve as jack points, especially for hydraulic floor jacks.
  4. Central Jack Points:
    • Front and Rear: Central jack points can lift either the front or rear end of the car. These are typically found near the front crossmember or the rear differential.

How to Identify Car Jack Points

The best way to identify the jack points on your vehicle is to consult the owner’s manual. The manual will provide detailed information and diagrams showing the exact locations. Additionally, many vehicles have visual indicators, such as notches or reinforced sections, that mark the jack points.

Using a Car Jack on Jack Points

Here is a step-by-step guide to using a car jack on the correct jack points:

  1. Preparation:
    • Park the car on a flat, stable surface.
    • Engage the parking brake and place wheel chocks behind the wheels that will remain on the ground.
  2. Position the Jack:
    • Locate the appropriate jack point using the owner’s manual or visual indicators on the vehicle.
    • Position the jack under the jack point. Ensure that the saddle of the jack is correctly aligned with the point.
  3. Lift the Car:
    • Slowly pump the jack handle to lift the car. Ensure the car is lifting evenly and the jack remains stable.
    • Lift the car to the desired height, allowing for the placement of jack stands if needed.
  4. Place Jack Stands:
  5. Check Stability:
    • Ensure the car is stable on the jack stands before working under it. Give the car a gentle push to confirm stability.

Common Mistakes to Avoid

  1. Lifting from Non-Reinforced Areas: Avoid placing the jack underparts that are not designed to support the vehicle’s weight, such as body panels or exhaust pipes.
  2. Ignoring the Owner’s Manual: Always refer to the owner’s manual for specific jack point locations and lifting instructions.
  3. Using Improvised Supports: Never use objects like bricks or wood blocks in place of proper jack stands. These can slip or break, leading to accidents.

Conclusion

Car jack points are essential for safely lifting and supporting a vehicle during maintenance and repairs. Knowing where these points are and how to use them correctly ensures the safety of both the vehicle and the person working on it. Always refer to your vehicle’s owner’s manual for precise information on jack points, and use the appropriate equipment to ensure a stable and secure lifting process. By following these guidelines, you can confidently and safely lift your car for any necessary work.
