Where Do You Jack Up A Car – Using Proper Jack Points

Knowing where to position the jack is the first critical step before you begin to lift any vehicle. If you’ve ever wondered “where do you jack up a car,” you’re asking the right question for safety and preventing costly damage. Lifting from the wrong spot can bend your car’s frame, puncture the oil pan, or cause the jack to slip with dangerous consequences. This guide provides clear, step-by-step instructions to locate the proper jacking points on any vehicle, ensuring you can change a tire or perform maintenance with confidence.

Where Do You Jack Up A Car

The correct answer depends entirely on your specific goal. Are you changing a tire, or do you need to lift the entire front or rear of the vehicle? There are two primary types of points you need to know: the designated jack points for an emergency tire change and the more robust lift points for using a floor jack and jack stands. Using the wrong one for the task is a common mistake.

Locating Factory Jack Points For Emergency Tire Changes

Your car’s manufacturer provides specific reinforced points meant for use with the small emergency scissor or bottle jack that comes with your vehicle. These are not always the same points you would use with a larger garage floor jack. You must find these before an emergency happens.

The most common locations for factory jack points are along the vehicle’s side sill or rocker panel. Look for a small notch, a reinforced section of metal, or sometimes a plastic cover that you can pop off. On many unibody cars, there is a seam of thicker metal just behind the front wheels and just ahead of the rear wheels. Your owner’s manual will have the definitive diagram and description, so it’s wise to check it now.

  • Behind Front Wheels / Ahead of Rear Wheels: Along the side sill, typically marked by a notch or cut-out.
  • Under Vehicle Reinforcements: Some SUVs and trucks have points on the axle or frame near each wheel.
  • Consult Your Owner’s Manual: This is the most reliable source. The manual will show exact locations and proper jack placement.

Identifying Proper Lift Points For Floor Jacks And Jack Stands

When you are working under the car for maintenance like an oil change or brake work, you need to use a hydraulic floor jack to raise the vehicle and then immediately support it with jack stands. This requires stronger, central lift points. Never work under a car supported only by a jack.

For this, you need to locate the vehicle’s front and rear central jacking points. These are substantial structural areas like the front crossmember, the rear differential (on rear-wheel-drive vehicles), or dedicated pads on the frame. Lifting here allows you to raise one entire end of the car safely, so you can place jack stands at the designated side points.

Common Central Front Lift Points

  • Front Crossmember: A sturdy beam between the front wheels, often behind the engine oil pan.
  • Engine Subframe: The robust structure that cradles the engine and suspension.
  • Manufacturer’s Central Pad: Some cars have a marked reinforced pad specifically for a floor jack.

Common Central Rear Lift Points

  • Rear Differential: The solid “pumpkin” housing on the axle of rear-wheel-drive vehicles. Never jack on the differential cover itself.
  • Rear Crossmember or Axle Tube: A solid beam or the tube of the axle itself.
  • Designated Frame Rails: On trucks and body-on-frame SUVs, the frame rails are the primary lift points.

Step-By-Step Guide To Safely Jacking Up Your Car

Follow these steps in order every single time you lift your vehicle. Rushing or skipping steps is how accidents happen.

  1. Park on a Solid, Level Surface: Concrete or asphalt is ideal. Never jack on dirt, gravel, or an incline. Engage the parking brake firmly. If lifting the rear, chock the front wheels. If lifting the front, chock the rear wheels.
  2. Gather Your Tools: You will need your jack, jack stands rated for your vehicle’s weight, a wheel chock, and possibly a piece of wood to pad the jack’s lifting point.
  3. Locate the Correct Point: Refer to your owner’s manual and identify the exact point for your task (tire change or central lift). Clean off any debris so the jack head has solid contact.
  4. Position the Jack Correctly: Center the jack saddle or pad directly under the lift point. For side jack points, ensure the jack is perpendicular to the vehicle to prevent slipping.
  5. Lift Slowly and Steadily: Pump the jack handle smoothly until the tire is just off the ground for a change, or until the end of the car is high enough to place jack stands. Watch the vehicle and jack for any signs of instability.
  6. Place Jack Stands Immediately: If you are going under the car, slide the jack stands under the manufacturer’s recommended support points (usually the reinforced pinch welds or frame). Lower the car slowly onto the stands.
  7. Perform a Stability Test: Before getting underneath, gently rock the car to ensure it is stable on the stands. The jack can remain in place as a secondary safety measure, but not supporting weight.

Critical Areas To Avoid Jacking At All Costs

Some parts of your car’s underbody look tempting but are extremely fragile. Jacking on these areas will almost certainly cause expensive damage and create a severe safety hazard.

  • The Oil Pan: This is thin metal or aluminum. It will crack or dent, leading to immediate oil loss and engine damage.
  • Exhaust Components: The exhaust pipes, catalytic converter, and muffler can crush easily and are not structural.
  • Floor Pan or Body Panels: The sheet metal of the car’s floor is not load-bearing. It will bend and buckle.
  • Suspension Arms or Control Arms: While strong, they are not designed for vertical jacking force and can be damaged or cause the jack to slip.
  • Steering Linkage: Bending these components will ruin your steering alignment and could cause a failure.

Special Considerations For Different Vehicle Types

Not all cars are the same. The proper jacking technique can vary significantly depending on your vehicle’s design.

Unibody Cars and Sedans

Most modern cars use unibody construction. The primary side jack points are often the reinforced pinch welds along the rocker panel. Use a jack pad or a block of wood to prevent bending the pinch weld. Always use the central front crossmember for lifting the front end, not the engine oil pan.

Trucks and Body-On-Frame SUVs

These vehicles have a heavy, solid frame. The best lift points are usually the frame rails themselves, both for side lifting and central lifting. Avoid the running boards, bumpers, or axle housings unless specified in the manual. The differential is often a safe central rear point.

Electric Vehicles (EVs)

EVs have high-voltage battery packs mounted in the floorpan. It is absolutely critical to use only the manufacturer-specified jack points to avoid puncturing the battery enclosure, which can lead to a serious fire. The manual for an EV is non-negotiable.

Essential Safety Gear And Best Practices

Your safety is paramount. Having the right equipment and following best practices is just as important as knowing where to place the jack.

  • Use Jack Stands, Always: Never, ever crawl under a vehicle supported only by a jack. Jacks are for lifting; stands are for supporting.
  • Check Weight Ratings: Ensure your jack and jack stands are rated for your vehicle’s gross weight. Add a safety margin.
  • Wear Safety Glasses: Debris can fall from the undercarriage.
  • Use Wheel Chocks: Chock the wheels that remain on the ground to prevent the car from rolling.
  • Work in a Well-Lit Area: You need to see clearly to identify points and ensure stable placement.

Frequently Asked Questions (FAQ)

Where is the jack point on a car for a tire change?

For a tire change, use the vehicle’s designated side jack points. These are typically found along the rocker panel, just behind the front wheel or ahead of the rear wheel, and are often marked by a small notch or reinforced section of metal. Always consult your owner’s manual for the precise location on your model.

Can I jack up my car from the control arm?

It is not recommended to jack up your car directly from the control arm or other suspension components. While strong, they are not designed as primary jacking points and doing so can damage the suspension bushings or ball joints, or cause the jack to slip. Always use the manufacturer-specified points.

How do I find the jacking points without the manual?

If you don’t have the manual, look for obvious reinforced metal sections or notches along the side sill. You can also search online for “[Your Car Year, Make, Model] jack points” to find diagrams or forum posts. For central lift points, look for the front crossmember or rear differential, but proceed with caution and verify if possible.

Is it safe to jack up a car on a slight slope?

No, it is not safe. You should only jack up a car on a firm, level surface like concrete or solid asphalt. Jacking on a slope, even a slight one, greatly increases the risk of the vehicle rolling or the jack tipping over, leading to a catastrophic failure.

What should I put between the jack and the car?

Using a small, sturdy block of wood between the jack saddle and the car’s lift point can help distribute the load and prevent damage, especially on unibody cars with pinch welds. Some jacks come with rubber pads, or you can purchase aftermarket jack pad adapters designed for this purpose.
