Place wheel chocks behind the wheels opposite the flat tire to prevent the car from rolling.
Selecting the Correct Car Jack
Determining Your Needs
Choosing the appropriate car jack for your specific requirements is crucial for both safety and effectiveness. Consider the following factors when making your selection:
- Vehicle Weight: The jack must have a lifting capacity that exceeds the weight of your vehicle. Refer to your owner’s manual for this information.
- Lifting Height: Determine the minimum lifting height required to access the intended work area under your vehicle. Consider the clearance between the jack point and the lowest point of the chassis.
- Stability: Opt for a jack that provides ample stability. This includes a wide base, sturdy construction, and anti-slip features to prevent the jack from toppling or slipping.
- Ease of Use: Choose a jack that is easy to operate, especially in tight spaces or under emergency situations.
- Jacking Points: Different vehicles have designated jacking points designed to support the weight of the vehicle safely. Ensure the jack is compatible with the jacking points on your car.
Types of Car Jacks
There are several types of car jacks available, each with its own advantages and limitations:
| Type | Pros | Cons |
|---|---|---|
| Scissor Jack | Compact, lightweight | Low lifting height, slow to operate |
| Floor Jack | High lifting capacity, stable | Bulky, requires space to operate |
| Hydraulic Jack | Powerful, easy to use | Can be heavy, requires maintenance |
| Bottle Jack | Compact, durable | Slow to operate, can be unstable |
Positioning the Car Jack Safely
Before using a car jack, it’s crucial to ensure it’s positioned correctly to prevent accidents and damage to your vehicle:
1. Park on a Level Surface
Park your car on a level, stable surface. Avoid inclines or slopes, as they can cause the jack to slip or shift when lifting the vehicle.
2. Select the Correct Jack Point
Locate the designated jack points on your vehicle. These points are usually reinforced areas on the frame or body where the jack should be placed for safe and effective lifting. Refer to your owner’s manual or have a mechanic assist you in identifying the correct jack points for your specific model.
| Vehicle Type | Typical Jack Point Location |
|---|---|
| Passenger Cars | Reinforced areas along the frame or body near the wheels |
| SUVs and Trucks | Reinforced areas on the front and rear axles or frame |
3. Place the Jack
Position the car jack directly under the designated jack point. Ensure the jack’s base is fully in contact with the ground and that it’s stable. Avoid placing the jack on soft or uneven ground, as it could sink or shift.
4. Secure the Car
Once the jack is in place, engage the vehicle’s parking brake to prevent it from rolling. Additionally, it’s recommended to place wheel chocks behind the wheels opposite the jack to ensure stability.
Raising the Vehicle with the Jack
Once the jack stands are in place, it’s time to lift the vehicle with the jack. Here’s a detailed step-by-step guide:
1. Position the Jack
Place the jack at the designated jack point specified in your vehicle’s manual. It’s usually located near the wheel you want to lift.
2. Stabilize the Jack
Before lifting, ensure the jack is stable. If it’s on soft ground, place a plywood or rubber pad underneath to prevent sinking.
3. Lift the Vehicle Slowly and Gradually
Pump the jack handle slowly and steadily. Stop pumping once the designated part of the vehicle (usually the frame or suspension component) makes firm contact with the jack stand. Do not over-lift as it can damage the frame or jack.
| WARNING: |
|---|
| Never place any part of your body under a vehicle that is supported only by a jack. Jack stands are essential for safety and should always be used. |
Continue pumping until the vehicle is securely supported on the jack stands, providing clearance to work on the suspension, tires, or brakes.
Choosing the Right Jack for Your Vehicle
Selecting the appropriate car jack for your vehicle is crucial for safety and convenience. Consider the following factors:
1. Vehicle Weight: Jacks are rated for specific weight capacities. Ensure the jack can handle the weight of your fully loaded vehicle.
2. Vehicle Height: Jacks come in different heights. Choose a jack with a lifting range that accommodates your vehicle’s ground clearance.
3. Jack Type: There are four main types of jacks: scissor jacks, bottle jacks, floor jacks, and hi-lift jacks. Scissor jacks are compact and lightweight, while bottle jacks offer high lifting capacity. Floor jacks provide stability and versatility, and hi-lift jacks are ideal for off-roading.
4. Safety Features: Look for jacks with safety features such as a wide base for stability, a ratchet or locking mechanism to prevent unintended lowering, and a built-in safety valve to prevent overloading.
5. Jack Point Compatibility: Your vehicle has designated jack points where it is safe to lift. Refer to your vehicle’s owner’s manual for the correct jack points and align the jack with these points to ensure proper distribution of weight.

Proper Placement of the Jack Pad
Identify the jack points on your car. These are designated areas where the jack should be placed to safely lift the vehicle. They are typically located on the frame of the car, near the wheels.
Before placing the jack, make sure the parking brake is engaged and the wheels are chocked.
Position the jack at the jack point closest to the flat tire.
Lift the Vehicle Gradually
Slowly pump the jack until the flat tire is about 6 inches off the ground. Do not lift the car too high, as this can make it unstable.
Once the car is high enough, place jack stands under the car for added stability. Do not rely on the jack alone to support the weight of the car.
