Raising a vehicle for maintenance or a tire change can seem daunting, especially when relying on a compact tool like a small jack. However, with the right knowledge, safety precautions, and proper technique, learning how to jack up a car with a small jack can be a straightforward and safe process for any car owner. This comprehensive guide will walk you through everything you need to know, from understanding your equipment to executing each step with confidence, ensuring you can perform necessary tasks safely and efficiently.
Understanding Your Small Jack: Types and Limitations
Before you begin, it’s crucial to understand the type of small jack you’re working with and its inherent limitations. Small jacks are typically designed for light-duty tasks, often included as standard equipment in a car’s trunk for emergencies like flat tires. They are generally not meant for extensive repair work where a vehicle might need to remain elevated for prolonged periods.
Common Types of Small Jacks
- Scissor Jack: This is the most common type of small jack found in vehicles. It operates by turning a screw mechanism with a crank handle, causing two arms to scissor upwards, lifting the car. They are compact, lightweight, and easy to store but can be slow to operate and less stable than other types. Their lifting capacity is usually limited.
- Bottle Jack: A hydraulic jack that resembles a bottle, hence its name. It uses hydraulic fluid to lift heavy loads. While some can be quite powerful, smaller bottle jacks are still relatively compact and can fit into tighter spaces. They offer quicker lifting than scissor jacks but require a flat, stable base for optimal performance.
- Small Trolley (Floor) Jack: Though often larger than scissor or bottle jacks, there are compact versions of trolley jacks available. These operate hydraulically and have wheels, making them easy to position under a vehicle. They generally offer more stability and ease of use compared to scissor jacks but are less portable due to their weight and bulk.
Limitations of Small Jacks
Regardless of the type, small jacks share common limitations that are vital to acknowledge for safety:
- Weight Capacity: Every jack has a maximum weight rating. Never exceed this limit. Attempting to lift a vehicle heavier than the jack’s capacity can lead to catastrophic failure. Always check your car’s weight and the jack’s specifications.
- Stability: Small jacks, particularly scissor jacks, offer less stability than larger professional equipment. They are designed for temporary lifting, not as a primary support for working under a vehicle. This is why jack stands are absolutely essential.
- Lift Height: Their maximum lift height might be limited, which could be an issue for taller vehicles or specific repair needs.
- Durability: Emergency jacks are not built for constant, heavy use. Regular use can lead to wear and tear, compromising their structural integrity over time.
Understanding these types and limitations forms the cornerstone of safe car elevation. Prioritizing safety above all else is paramount when working with vehicles.
The Absolute Priority: Safety First
Working under a car, even for a short period, presents significant hazards. A vehicle falling from a jack can cause severe injury or even death. Therefore, adhering to strict safety protocols is not just a recommendation; it is an absolute requirement.
Essential Safety Equipment
Beyond your jack, you will need additional safety gear:
- Jack Stands: These are non-negotiable. Jack stands are designed to support the vehicle’s weight once it’s lifted, providing a stable and secure platform. Your small jack is merely for lifting, not for sustaining the load. You should always use two jack stands, and ideally four for more extensive work, placed under appropriate support points.
- Wheel Chocks: These are wedges placed in front of and behind the wheels that remain on the ground to prevent the car from rolling. Even on a flat surface, a car can shift.
- Gloves: Protect your hands from dirt, grease, and potential scrapes.
- Flashlight or Headlamp: Crucial for illuminating dark undercarriage areas, ensuring you can clearly see jack points and other components.
- Safety Glasses: Protect your eyes from falling debris or fluids.
Critical Safety Precautions
- Level and Hard Surface: Always jack up your car on a firm, flat, and level surface like concrete or asphalt. Never attempt to lift a car on soft ground (grass, gravel, dirt) or a sloped surface, as this can cause the jack to sink, shift, or tip over.
- Engage Parking Brake: Always engage your car’s parking brake (emergency brake) fully before attempting to lift.
- Shift to Park/Gear: For automatic transmissions, put the car in “Park” (P). For manual transmissions, put it in first or reverse gear.
- Wheel Chocks: Place wheel chocks on the wheels diagonally opposite to the corner you are lifting. For example, if you’re lifting the front-right wheel, chock the rear-left wheel. If lifting the entire front end, chock both rear wheels.
- Owner’s Manual: Consult your vehicle’s owner’s manual to locate the specific, approved jack points and jack stand points. These points are reinforced to support the vehicle’s weight. Using incorrect points can damage your car or cause it to slip off the jack.
- Never Rely Solely on the Jack: Once the vehicle is lifted to the desired height, always immediately place jack stands under the designated support points and gently lower the vehicle onto the stands. The jack is for lifting; the stands are for holding.
- Clear Work Area: Ensure your work area is free of obstructions and tripping hazards.
By consistently applying these safety measures, you drastically reduce the risk of accidents, allowing you to focus on the task at hand with peace of mind.
Gathering Your Tools: What You’ll Need
Having all the necessary equipment ready before you start will make the process smoother and safer. Here’s a checklist:
- Small Jack: Your primary lifting tool.
- Jack Stands: At least two, rated for your vehicle’s weight.
- Wheel Chocks: At least two.
- Lug Wrench: For loosening and tightening lug nuts.
- Owner’s Manual: Absolutely essential for identifying jack points.
- Gloves: For protection.
- Flashlight/Headlamp: For visibility.
- Piece of Wood/Rubber Pad (Optional): Can be placed between the jack and the car’s frame to prevent damage or provide extra grip, especially with certain jack types.
- Brake Cleaner/Penetrating Oil (Optional): If lug nuts are stubborn.
Having these items within reach will ensure a seamless workflow as you proceed with the task.
Locating the Correct Jack Points
One of the most critical steps to safely jack up a car with a small jack is correctly identifying your vehicle’s designated jack points. These are specific, reinforced areas on the car’s frame or body designed to withstand the vehicle’s weight without sustaining damage or collapsing. Using an incorrect point can bend the frame, damage suspension components, or cause the car to become unstable on the jack.
Where to Find Them
- Owner’s Manual: This is your primary and most reliable source. The manual will contain diagrams and descriptions of the precise jack points for your specific make and model.
- Sill Seams/Pinch Welds: For many unibody cars, the jack points are located along the pinch weld seam (the folded metal edge) that runs along the bottom of the car, just behind the front wheels and in front of the rear wheels. There are usually small notches or arrows indicating the exact spot.
- Frame Rails: On body-on-frame vehicles (like some trucks and SUVs), the frame rails themselves are typically the jack points.
- Rear Axle/Front Crossmember: For lifting an entire end of the vehicle, there might be a central jack point on a sturdy rear axle housing or a reinforced front crossmember. These are generally stronger and allow for a more balanced lift.
Differentiating Jack and Jack Stand Points
It’s important to note that a jack point (where you lift the car with the jack) and a jack stand point (where the jack stand supports the car) are often different, though sometimes they can be close. The jack point needs to be strong enough to withstand the concentrated force of the jack, while the jack stand point needs to provide a stable, flat surface for the stand. The owner’s manual will detail both. If you are using a jack point to lift, you will then need to find an adjacent, equally strong point to place the jack stand, such as a sturdy part of the frame, a subframe, or a suspension component that is clearly designed for load-bearing.
Never place a jack or jack stand on:
- Plastic trim
- Fuel lines or brake lines
- Oil pan or transmission housing
- Suspension arms not designed for jacking
- Any unreinforced body panel
Step-by-Step: How to Jack Up a Car with a Small Jack
With safety protocols ingrained and tools at the ready, let’s walk through the exact procedure for lifting your car.
1. Prepare the Vehicle and Work Area
- Park on a Level Surface: Ensure your car is on a hard, flat, and level surface.
- Engage Parking Brake: Pull the parking brake firmly.
- Shift to Park/Gear: Put an automatic car in “Park” (P) or a manual in first or reverse gear.
- Chock Wheels: Place wheel chocks on the wheels that will remain on the ground. If lifting the front, chock both rear wheels. If lifting a single corner (e.g., for a flat tire), chock the wheel diagonally opposite.
2. Loosen Lug Nuts (Slightly)
If you’re changing a tire, it’s easier to loosen the lug nuts before the car is fully off the ground. Use your lug wrench to turn each nut about a quarter to half turn counter-clockwise. Don’t remove them entirely; just break their initial tightness. This prevents the wheel from spinning when the car is airborne.
3. Position the Jack
Refer to your owner’s manual for the precise jack point for the corner you intend to lift. Slide the small jack under the designated point. If using a scissor jack, ensure its top cradle correctly engages with the pinch weld or frame point. For bottle or trolley jacks, ensure the pad is centered on the designated jacking point. If you have a rubber pad or small piece of wood, place it between the jack and the car for added protection.
4. Raise the Vehicle Slowly
Begin to operate your jack according to its type (crank for scissor jack, pump handle for hydraulic).
* Lift steadily and slowly.
* Watch the car carefully. Ensure it’s lifting evenly and that the jack isn’t slipping or leaning. If anything looks unstable, stop immediately, lower the car, and reassess.
* Lift just enough to get the tire clear of the ground and allow enough room for the jack stand to be placed.
5. Place Jack Stands
Once the car is lifted, immediately slide the jack stand(s) under the vehicle. Locate the jack stand points as indicated in your owner’s manual, which are typically robust parts of the frame, subframe, or suspension components adjacent to your jacking point. Ensure the jack stand’s saddle makes firm contact with the support point.
6. Lower Car Onto Stands
Slowly and carefully begin to lower the jack. Allow the vehicle to gently rest its weight fully onto the jack stands. The jack should now be lightly supporting the vehicle or completely disengaged. The jack stands are now bearing the vehicle’s weight. If you’re only working on one corner, leave the jack in place for an extra layer of safety, but ensure the car’s weight is predominantly on the stands.
7. Perform Work
With the car securely supported by jack stands, you can now safely perform your intended work, whether it’s changing a tire, inspecting brakes, or other maintenance.
8. Raise Car Off Stands
When you’re finished, position your jack back under the original jack point. Raise the car slightly, just enough to relieve pressure from the jack stands.
9. Remove Jack Stands
Carefully remove the jack stands from under the vehicle. Double-check that all stands are clear before proceeding to lower the car.
10. Lower Car Completely
Slowly and steadily lower the car all the way down to the ground using your jack. Once the car is fully on the ground and the jack is completely retracted, remove the jack from under the vehicle.
11. Tighten Lug Nuts
If you removed a wheel, tighten the lug nuts in a star pattern. This ensures even pressure and prevents the wheel from warping. Tighten them as much as you can by hand, then use a torque wrench to tighten them to the manufacturer’s recommended specifications (found in your owner’s manual). If you don’t have a torque wrench, get them professionally torqued as soon as possible.
12. Final Check
Walk around the vehicle. Ensure all tools are put away, the work area is clear, and the car looks stable. Remove the wheel chocks.

Common Mistakes to Avoid
Even with a clear guide, it’s easy to overlook crucial details. Being aware of common mistakes can help you prevent them.
- Using the Wrong Jack Points: As emphasized, this is a major safety risk and can cause severe damage to your vehicle’s frame, suspension, or undercarriage components. Always consult your owner’s manual.
- Not Using Jack Stands: This is perhaps the most dangerous mistake. A jack can fail without warning. Never, under any circumstances, get under a vehicle that is only supported by a jack.
- Working on Uneven or Soft Ground: The jack can shift, sink, or tip, leading to the car falling. Always use a firm, level surface.
- Forgetting Wheel Chocks: Even a slight incline or bump can cause a car to roll, shifting it off the jack or stands.
- Not Engaging the Parking Brake: This allows the wheels to spin freely, increasing the risk of the car moving.
- Over-Extending the Jack: Pushing a jack beyond its maximum height or capacity can lead to structural failure.
- Ignoring the Jack’s Weight Capacity: Always verify that your jack is rated to lift your specific vehicle’s weight.
- Getting Under a Hot Car: Allow the engine and exhaust system to cool down before working underneath, to prevent burns.
- Forgetting to Loosen Lug Nuts First: Trying to loosen lug nuts while the wheel is off the ground can cause the wheel to spin, making it difficult and potentially dislodging the car from the jack.
- Leaving Tools Under the Car: Always ensure no tools are left underneath the vehicle before lowering it completely.
By actively avoiding these pitfalls, you significantly enhance the safety and success of your car maintenance tasks.
When to Call a Professional
While knowing how to jack up a car with a small jack is a valuable skill, there are situations where it’s best to defer to professional mechanics.
- Complex Repairs: If the repair requires specialized tools, extensive disassembly, or a deep understanding of automotive systems (e.g., major engine work, transmission removal), it’s best left to experts.
- Unusual Car Behavior: If your car is making strange noises, leaking fluids, or exhibiting other concerning symptoms that you can’t identify, a professional diagnostic is necessary.
- Damaged Jack Points: If the designated jack points on your vehicle are rusted, bent, or otherwise compromised, attempting to lift the car could be dangerous.
- Lack of Proper Equipment: If you don’t have suitable jack stands, wheel chocks, or a jack rated for your car’s weight, do not attempt to lift the vehicle.
- Safety Concerns/Unease: If you feel uncomfortable or unsafe at any point, stop and seek professional assistance. Your safety is paramount.
- Heavy or Unstable Vehicles: Some larger SUVs or trucks might require more robust jacking equipment than a small jack can provide, or they might have a higher center of gravity, making them inherently more unstable to lift.
Knowing your limits and when to seek professional help is a sign of responsible car ownership.
Maintaining Your Small Jack
Proper maintenance ensures your jack remains a safe and reliable tool.
- Cleanliness: Keep your jack clean and free of dirt, grit, and rust. Wipe it down after each use.
- Lubrication (Hydraulic Jacks): For bottle or trolley jacks, periodically check and top up the hydraulic fluid if needed, and lubricate moving parts according to the manufacturer’s instructions.
- Storage: Store your jack in a dry place to prevent rust.
- Inspection: Before each use, inspect the jack for any signs of damage, cracks, bends, or leaks. Never use a damaged jack.
- Scissor Jack Care: For scissor jacks, ensure the screw mechanism is clean and lightly greased to ensure smooth operation.
A well-maintained jack is a safe jack, ready when you need it most for unexpected roadside events or routine maintenance.
Mastering how to jack up a car with a small jack is a fundamental skill for any vehicle owner, empowering you to perform basic maintenance and handle emergencies like a flat tire. By strictly adhering to safety protocols, understanding your equipment, and following a methodical approach, you can perform these tasks confidently and securely.
