Knowing where to put car jack is one of the most fundamental and critical skills for any driver. Finding a solid, level surface and the proper lift point on your vehicle’s frame is essential before using a jack. Getting this wrong can lead to severe vehicle damage, injury, or a car falling off the jack. This guide will walk you through every step to ensure you lift your car safely and correctly every single time.
We will cover how to find your vehicle’s specific jack points, the different types of jacks and their uses, and the step-by-step process for a safe lift. You’ll also learn common mistakes to avoid and what to do in an emergency situation. Let’s get started with the absolute basics you need to know.
Where To Put Car Jack
The primary locations for a car jack are designated by the manufacturer and are typically found along the vehicle’s frame or unibody. These reinforced metal sections are engineered to handle the concentrated pressure of a jack. Using any other point, like the floor pan, oil pan, or suspension components, can cause expensive and dangerous damage.
There are two main categories of jack points: the dedicated points for your vehicle’s emergency scissor jack and the more general lift points used for floor jacks and jack stands.
Locating Your Vehicle’s Official Jack Points
Your car’s manual is the ultimate authority. It contains diagrams showing the precise locations. If you don’t have the manual, you can usually find a digital copy online by searching your car’s make, model, and year.
For most modern unibody vehicles, the common emergency jack points are along the side sills or rocker panels. Look for a small notch, a reinforced section, or sometimes a plastic cover that you can remove. These are specifically designed for the small jack that comes with your spare tire.
Signs of a Proper Side Sill Jack Point
- A distinct notch or groove in the metal seam under the doors.
- A section of the plastic trim that feels more solid or has an access panel.
- A marked area with a triangle or jack symbol on the sill (less common).
- Consulting your manual is the best way to be certain, as some points are subtle.
Using A Floor Jack On Frame And Pinch Weld Points
A floor jack provides a much stable and easier lifting experience. Its larger saddle can be positioned under more substantial parts of the vehicle’s frame. Common safe points for a floor jack include the front crossmember, the rear differential (for rear-wheel drive), or the central subframe.
Many vehicles also have a reinforced “pinch weld” along the underside. This is the vertical seam where two body panels meet. Some manufacturers specify this as a lift point, but you must use a proper pinch weld adapter or a block of wood on your jack’s saddle to prevent bending the metal.
Special Considerations For Trucks And SUVs
Body-on-frame trucks and SUVs have very clear and robust frame rails running the length of the vehicle. These are ideal for floor jack placement. Look for the solid, rectangular steel beams behind the front wheels and ahead of the rear wheels.
Avoid placing the jack on the axle housing, suspension arms, or the truck’s bed. While the differential is sometimes used, it’s best to target the flat, strong sections of the frame itself for the most secure lift.
Preparing To Jack Up Your Vehicle
Preparation is 90% of the job. Rushing this stage is the leading cause of accidents. Always follow these steps in order before you even touch the jack handle.
Finding A Safe And Level Surface
Never jack up a car on a slope, soft ground, or gravel. Concrete or solid asphalt is essential. The ground must be perfectly level to prevent the vehicle from rolling once it’s lifted. If you have a flat tire on an unsafe road, try to slowly drive the car to the nearest level, solid area, even if it means driving on the flat tire for a short distance.
Essential Safety Gear And Equipment
- Jack Stands: These are non-negotiable. Never work under a vehicle supported only by a jack.
- Wheel Chocks: Use these to block the wheels that will remain on the ground.
- Gloves and Safety Glasses: Protect your hands and eyes from grease and debris.
- A Flashlight: To clearly see the jack points and your work area.
Securing The Vehicle Before Lifting
- Park the car completely, put the transmission in “Park” (or first gear for manual), and engage the parking brake firmly.
- Place wheel chocks snugly against the tires diagonally opposite from the end you’re lifting. For example, if lifting the front right, chock the rear left tire.
- Gather all your tools and jack stands within easy reach so you don’t have to leave the vehicle while it’s elevated.
Step-By-Step Guide To Jacking Up Your Car
Follow these instructions carefully for a safe and successful lift. We’ll cover using both a common scissor jack and a hydraulic floor jack.
How To Use A Scissor Jack Correctly
The scissor jack that comes with your spare tire is for emergency tire changes only. It is not for prolonged repairs. Here is the proper method:
- Locate the exact jack point near the flat tire, as shown in your manual.
- Assemble the jack and the lug wrench handle. Ensure the jack’s top groove or pad aligns with the vehicle’s notch or reinforced point.
- Begin turning the handle clockwise. The jack will start to rise and make contact with the car.
- Continue turning steadily until the flat tire is about 2-3 inches off the ground. Do not lift the vehicle any higher than absolutely necessary.
- Once the tire is changed, lower the car slowly by turning the handle counter-clockwise. Remove the jack and stow everything securely.
Proper Technique With A Hydraulic Floor Jack
A floor jack is more stable and better for maintenance work. The process is similar but with a broader lifting point.
- Position the floor jack saddle under a central front or rear lift point, like the crossmember or a reinforced section of the pinch weld.
- Pump the jack handle slowly and smoothly. Watch the jack’s contact point and the vehicle as it rises.
- Once the car is high enough, immediately place jack stands under the proper support points, usually the solid frame rails or dedicated stand points near each wheel.
- Gently lower the jack until the vehicle’s weight rests entirely on the jack stands. The jack can then be slighty lowered but often left as a secondary safety backup.
- Before going under the vehicle, perform a stability test by gently rocking the car. It should feel solid on the stands.
Placing Jack Stands For Maximum Security
Jack stands are your primary safety. They must be placed on strong, flat sections of the vehicle’s frame or on the dedicated stand points, which are often different from the jack points. Never use concrete blocks, wood piles, or other unstable objects. Ensure the stand’s locking pin is fully engaged and that the vehicle is resting on the stand’s saddle, not on the lifting arm.
Common Jack Point Mistakes To Avoid
Even experienced DIYers can make errors. Being aware of these common pitfalls will keep you and your vehicle safe.
Dangerous And Damaging Placement Areas
- The Oil Pan or Transmission Pan: These are made of thin metal and will crack.
- The Exhaust System: It will crush or bend easily.
- Suspension Components: Control arms and springs are not designed for vertical jacking force.
- The Front or Rear Bumper: Plastic and reinforcement bars will not hold the weight.
- The Floor Pan or Rocker Panel (if not reinforced): This thin sheet metal will buckle instantly.
Consequences Of Incorrect Jack Placement
Placing the jack in the wrong spot can lead to immediate and costly damage. You might puncture the oil pan, requiring a full engine oil change and a new pan. You could bend the frame or unibody, which affects alignment and is very expensive to repair. The worst-case scenario is the jack slipping or the metal giving way, causing the vehicle to fall. This can result in serious injury or even fatalaty.
Vehicle-Specific Jack Point Guidance
While the principles are universal, some vehicle types have particular nuances.
Jack Points For Sedans And Hatchbacks
Most modern sedans use unibody construction. Rely heavily on the owner’s manual. The side sill notches are for the emergency jack. For a floor jack, look for the front crossmember behind the bumper or the rear axle beam or torsion bar. The central front subframe is often a good, solid choice if you can access it.
Jack Points For Crossovers And Minivans
These vehicles are heavier, so using the correct points is even more critical. The side sill points are usually present. For a floor jack, locate the front and rear subframes. Be cautious, as plastic underbody covers can hide the proper lift points. You may need to feel around or consult a repair manual for detailed diagrams.
Jacking Up Electric And Hybrid Vehicles
Electric vehicles often have high-voltage battery packs mounted in the floorpan. It is extremely important to avoid these. The manual will explicitly show the approved jack points, which are designed to keep the jack far from the battery enclosure. Some EVs have specific jacking mode in their settings to stiffen the suspension; check your manual for such features.
Emergency Roadside Jacking Procedures
Getting a flat on a busy road is stressful. Your priority is visibility and safety from traffic.
Safety Tips For Changing A Tire On The Road
- Pull as far off the road as possible, onto the shoulder or a side street.
- Turn on your hazard lights immediately. Use road flares or reflective triangles if you have them.
- Keep all doors locked except the one you are using, and stay aware of passing traffic.
- Follow your vehicle’s manual for the emergency jack point exactly. Do not try to improvise.
- Once the spare is on, drive to the nearest service station to have the flat repaired or replaced. Don’t continue a long journey on a small spare tire.
FAQ Section
Where Are The Jack Points On My Car?
The definitive answer is in your vehicle’s owner’s manual. Look for a section labeled “Changing a Tire” or “Jacking.” It will have an illustration. If you’ve lost the manual, search online for “[Your Car Year, Make, Model] owner’s manual PDF.”
Can I Jack Up My Car From The Control Arm?
No, you should not jack up your car from the control arm. Control arms are part of the suspension and are designed to pivot, not to bear the vehicle’s full weight vertically. Jacking from here can bend the arm, damage the bushings, and cause alignment issues.
Is It Safe To Use A Jack On The Differential?
On some rear-wheel-drive vehicles with a solid rear axle, the differential housing can be a safe jack point. However, this is not universal. Check your owner’s manual. If approved, ensure the jack’s saddle is centered on the differential cover to prevent slippage. For independent rear suspension, avoid the differential.
How Many Jack Stands Do I Need?
For most work, you need two jack stands. If you are lifting the entire front or rear of the car, place a stand under the frame rail on each side. For maximum safety when lifting the entire vehicle, four jack stands are ideal, one at each corner’s support point.
What Is The Best Surface To Put A Car Jack On?
The best surface is a smooth, level, and solid concrete floor. Asphalt can be acceptable if it is not soft from heat. Never use dirt, grass, or gravel, as the jack can sink or shift. If you must work on a softer surface, place a large, thick piece of plywood under the jack to distribute the weight.
Knowing where to put a car jack is a skill that empowers you to handle basic maintenance and emergencies safely. Always prioritize a level surface, the correct manufacturer-specified lift points, and the use of jack stands. Taking those extra minutes to prepare and double-check your setup is the best insurance against damage and injury. With this knowledge, you can approach lifting your vehicle with confidence and caution.
