Tire jack how to use


How to Use a Car Jack Safely

When you hear that thumpa-thumpa-thumpa sound while driving down the road, you know one of your tires is flat. And that means you'll soon be changing it yourself, if you're not lucky enough to have access to roadside service for your vehicle. If the mere thought of using a car jack makes you break out in a cold sweat—and it does for many people—not to worry! Just study these three video clips and follow these six simple steps, and you'll be able to get your vehicle in the air in short order without hurting it or—more important—you.

Step 1: Find a Safe Place to Pull Over

Get off the road and as far away from traffic as you can. If you're on a highway and near an exit, take it. The goal is to get off the road entirely and on to solid, level ground—such as a parking lot—where you can use a car jack safely. Failing that, you want to find your way to a road or street with as little traffic as possible, where you can pull off to the side, away from the flow of cars, and be on a spot solid enough to support a jack. If you're on a highway and can't get off, you'll just have to find the safest location you can; you can't drive for miles on a flat tire without destroying it and possibly damaging your vehicle. In that case, pull over to the right shoulder, as far off the road as possible. Make sure you're on a solid, level surface, so that the jack doesn't sink into the ground rather than lifting the car. A soft surface might also cause the jack to lean to one side as it's lifting the car, which can cause the car to fall.

Step 2: Secure Your Vehicle

Make sure the vehicle's engine is off, that it's in park, and that the parking brake is engaged. If you happen to have something that you can use to block a tire (a brick, a piece of wood, or a large rock will do), place it under the tire at the opposite corner of the car from the corner you're going to jack up (e.g., if you're jacking up the right front, block the left rear tire). This is further insurance that the car will not roll off the jack. If you have passengers, it's a good idea to have them exit the car, but it's not absolutely necessary.

Step 3: Locate the Jack and Jacking Points

In most vehicles, the jack is stored in the trunk or in an SUV's wayback, under the cargo-floor cover. After you find it, you need to locate the jacking points on the car's body, where the jack engages. The jacking points for most vehicles are reinforced metal ribs specifically designed to safely lift the vehicle. On most vehicles, there are four jacking points. They're located under the car's rocker panels, just behind the front wheels and just ahead of the rear wheels. In the above video, our Car and Driver tech is pointing to the right front jacking point on the Hyundai Sonata sedan we're about to lift. To be sure about the jacking point locations for your vehicle, check your owner's manual.

Step 4: Position the Jack

Most car jacks have a slot at the top, on their engagement flange, that slips onto the jack point's reinforced rib—but your car may have a different setup, so check your owner's manual to be sure you understand exactly how your jack works with the jacking point. In the above video, our tech needs to spin the jack down first, so it can fit under the car before he begins jacking it up.

Step 5: Jack Up the Car

Turn the jack handle clockwise slowly until the flat tire comes off the ground. Take your time and make sure that the jack remains positioned straight up and down as it lifts the car. You don't want the jack leaning, because it won't hold the car securely that way. If you're lifting the car to get under it, to do some work, or to change the oil, you must place a jack stand under the rocker panel near the jack and snug it up to the car's body. This will ensure that the car cannot fall on you, should the jack slip or fail entirely.

Safety note: If you're jacking up the car to work on it at home, it's a good idea to use a more robust floor jack—the kind with the long handle that you pump (pictured above). This is the type of jack used at repair shops and in the pits at car races, because it's much stronger and more stable than a car's onboard jack. A jack stand placed in the proper position is pictured below, alongside a floor jack (with its handle removed).

Step 6: Lower the Car


When you're ready to lower the car, slowly unwind the jack handle in the opposite direction (counterclockwise) until the car's tire is firmly in contact with the ground and you can remove the jack. Return the jack to its storage location, secure it, and you're almost ready to roll. But before you fire up the engine, don't forget to remove whatever you used to block a tire, or you might think the parking brake is stuck on when you try to drive off.

Which Car Jack Should I Use?

There are two main types of car jacks that you can choose to use on your car at home: scissor jacks and floor jacks. While they both do the same thing (lift your car up) they’re slightly different so it’s best to think about how you’ll be using it to decide which one you want.

Let’s take a closer look at these two car jacks below.

Floor Jacks:

Floor jacks are the most widely used car jack and give you stability with heavy loads. They normally have four wheels so you can move it, as well as a long handle that lets the operator pump the hydraulic lift to get the car off the ground.

Floor jacks are useful if you regularly work on your car in a home garage, and are also great for lifting cars on to jack stands (which we’ll get to later). Make sure you choose a jack that’s been approved to lift the weight of your vehicle.

Scissor Jacks:

Scissor jacks are small and portable, so they’re better if you’re looking for something to carry in your boot for roadside repairs. In fact, some car manufacturers supply a scissor jack with a spare wheel, so you might have one anyway.

You can buy scissor jacks that work with any car, but most of them are built especially for a particular make or model. That’s because you need to use them on specific lifting points on the car, which you can find in your owner’s manual.

Unlike floor jacks which use a hydraulic pump, scissor jacks use a simple screw mechanism to provide the lifting power. This is what makes them so small, lightweight and portable.

The jack you choose will depend on what kind of maintenance and repairs you normally carry out on your car. If you do a lot of your own maintenance work, like changing the oil filter and brake pads, we’d recommend a floor jack. If you’ll be using it for changing the wheels in an emergency, a scissor jack is an affordable choice that’s portable and easy to use.

How to Use a Car Jack

Car jacks are easy to use once you know the basics. Here, we tell you how to use both floor and scissor jacks to lift your car safely, and how to put your car on to jack stands.

For both jack types, always make sure your car is in first gear with the handbrake on to prevent the car rolling. You can also use chocks to stop the wheels from moving, but they’re not always necessary.

Using a Floor Jack:
  1. Before you start jacking up your car, you need to find out where its safe lift points are – these are the strongest parts of the vehicle’s chassis (normally just in front or behind the wheel arches). You can usually find the exact points in your owner’s manual.
  2. Manoeuvre the jack under the lift points of the car, so that the base plate is directly beneath the sill of the frame.
  3. Begin lifting the jack by pumping the height adjustment arm. Go slowly when the base plate approaches the car so that you can align it properly and make sure that the weight is evenly distributed.
  4. Continue to pump the height adjustment arm until the car is raised off the ground. Most floor jacks also have a locking mechanism which will keep the arm in place so that you can move around underneath the car safely.
  5. When you’re ready to lower your car, move the height adjustment arm to its vertical position and twist it. This releases the air in the pump, lowering the car slowly to the ground.

Using a Scissor Jack:
  1. It’s crucial that you use a scissor jack directly on the car’s safe lift points, so make sure you know exactly where these are located. Often, scissor jacks can only be used at specific points on the chassis, with a specially made base plate that fits into grooves on the car’s undercarriage.
  2. Scissor jacks normally come in two parts: the jack itself and a handle which you have to attach before you use it. Once the jack is in place, slide the handle on and begin turning in the direction marked ‘R’ (raise). Remember to go slowly as the jack approaches the car’s undercarriage to make everything is properly aligned.
  3. Once the car is fully raised, we’d recommend that you remove the handle so you don’t trip over it, and also to prevent it from getting knocked.
  4. To lower the car, simply crank the turning handle in the opposite direction – often marked ‘L’ (lower) – until all four wheels are safely back on the ground.

Using Jack Stands:

Jack stands are handy if you’re working under your car for long periods and need extra stability. It’s also a good idea to you use jack stands if you’re storing a classic car, as raising the car off the ground will prevent the tyres becoming warped.

Here’s how to jack your car up on to a set of jack stands.

  1. Find the safe lift point at the front of your car and follow the steps above to safely lift the front section of the car.
  2. Once the front two wheels are fully off the ground, place two jack stands at the safe lift points on each side of the car. Then, slowly lower the jack so that the two jack stands take the weight of the front section of the car.
  3. From here, it’s simply a case of repeating the steps above to lift the rear of the car on to jack stands, too, so that all four wheels are completely off the ground and the car’s weight is supported by all four jack stands.
  4. When you want to lower the car back down, raise the car higher at one end with the jack and remove the stands. Then, do the same for the other side, lowering the car slowly back on to its wheels.

Essential Jack Safety Advice

Jacking up a car can be dangerous, so make sure you take your time, use the right equipment and find your car’s safe lifting points. Here are some extra safety tips:

  • Always make sure the car is in first gear with the handbrake on. This limits the risk of rolling.
  • If you don’t have your owner’s manual, head online to try and figure out where the safe lift points are. Never jack your car if you aren’t sure where it’s safe to lift.
  • Make sure the jack and jack stands you choose are suitable for the weight of your car.
  • Only ever use a jack on a flat, level and hard surface.
  • If you’re working under the vehicle, always use jack stands. A jack is only good for holding a car while you’re changing the wheel, not for when you’re actually under the car.

How to choose and how to use a jack

Every driver, without exception, at least once in his life is faced with the need to use a jack. This wonderful device is a magic wand of salvation when changing a wheel. With it, you can easily raise the car and hold it in this position for the required amount of time. Unfortunately, driving courses do not teach beginners how to use a jack, and therefore they are forced to master such knowledge on their own.

How to use the jack

Car jack refers to devices that have a simple design. In the past, this device was used by the Greeks in order to forcefully open the gates of the acropolises. The first hydraulic jack for a car was created by the famous inventor Lunati. Since the invention of the lifting device until today, the mechanism has been an integral part of the automotive tool kit.

Remember, the jack is used exclusively for lifting vehicles! To keep it at a raised height, this device alone is not enough and not enough. Do not risk your health and your life, do not climb under a car that rests solely on a jack.

How to behave with him

The video shows how to choose the right jack:

There are several rules for the safe use of the jack, because, despite the simple design, improper use of the mechanism can be life-threatening:

  1. Before jacking up the vehicle, make sure it is on level ground. Otherwise, the vehicle will be poorly secured and may start to move while in a raised position. If you can't find a level surface, park near a high curb, turn your wheels towards it and block them well.
  2. Blocking the wheels on the opposite side of the hill is required even if your vehicle is placed on a perfectly level surface. To do this, use pads, bricks or wedges.
  3. Do not jack up the car while in forward or reverse gear. In addition, when working with the front wheels, apply the handbrake and block the rear wheels. When working with the rear wheels, you need to block the front ones.
  4. The lifting device is installed only in a place specially designed for this purpose. If you need to install the mechanism in another place, then make sure that it is strong enough to support the weight of the car. In situations where you are in doubt where to install, choose a body or front suspension beam.
  5. Do not lift the car in jerks, the action must be carried out smoothly.
  6. Use props to keep the vehicle up. They are installed near the jack after lifting. Lock them at the required height and you can safely remove the lifting device. Remember, bricks, stones and wedges do not fit the role of props at all .
  7. Check that the vehicle is securely fixed after lifting. To do this, shake it slightly. If you don't, you risk injury.
  8. Lowering the machine must be as careful as raising it.

Which one to buy

In order to be 100% sure of your safety, it is not enough just to follow the rules for using this mechanism, you also need to choose the right one for your car. Unfortunately, how to choose a car jack is also not taught in a driving school, so many inexperienced drivers buy something completely different from what suits them, and are convinced of this only when they start using their purchase for its intended purpose.

The rules for choosing a lifting device are very simple and unpretentious:

  1. To correctly determine the required load capacity of this attachment, you need to know the weight of your vehicle.
  2. Domestic lifting devices are in no way inferior in quality to foreign ones, so there is not much point in overpaying.
  3. Match the specifications of the lifting device with your vehicle when purchasing. They should match as closely as possible. It is better that the carrying capacity of the device exceeds the weight of the car, than vice versa.
  4. Consider its dimensions, because you will carry this mechanism in the trunk.
  5. If the platform for its installation on a car, located under the bottom, is flat, then you can purchase a jack of any type, but if there are recesses, then only a special type will do.

Types of jacks

Knowing their typical features will also help you choose a car jack. For example, for its use in the walls of the garage, it is best to buy a hydraulic bottle jack.

Depending on the principle of operation, a distinction is made between mechanical and hydraulic lifting devices. Most often, complete with a car, you get a mechanical jack. Such devices, in turn, may be lever or folding.

The world is slowly forgetting about levers, they are no longer produced and sold. At this time, the popularity of folding is gaining momentum. Folding models are great for lifting cars weighing less than 2 tons. Their small carrying capacity makes them convenient and easy to use, store and transport. You can also safely say that folding jacks are very reliable.

Hydraulic jacks are chosen for vehicles with a large weight and, accordingly, dimensions. Their power affects weight and cost. Distinguish rolling and telescopic. The first is better not to operate in the middle of the road. Due to their significant carrying capacity, their purpose is car services and garage repairs of minivans, minibuses and jeeps. Telescopic jacks raise the car due to the operation of the piston of the hydraulic mechanism. Hydraulic lifting devices must only be stored and transported in an upright position , otherwise the working fluid will end up on your floor or in the trunk. These jacks require special attention: you need to constantly monitor the oil level and the tightness of the seals and valves.

Choosing a car jack is not difficult if you know the characteristics of your car, decide which size and weight suits you, and decide on the amount that you are willing to spend on a future purchase.

How to use the jack, 3 types

The jack is your insurance against a tire breakdown and the need to replace it on the road. There are several types of construction of lifting mechanisms, and the rules for their operation differ significantly. While the general recommendations remain the same, knowledge , how to use the jack , lying in your trunk or standing in the corner of the garage - a guarantee of the health of your car and your safety.

General Rules for Using Jacks

Before we look at how to use a rack and pinion jack, here are some general safety rules for lifting a car:

  • must be in first or reverse gear. For automatic, make sure the "Park" position is selected;
  • put the car on the handbrake;
  • wheels must be locked with stops to prevent slipping;
  • there must be no people in the car at the time of lifting. If conditions permit, at least part of the luggage should be unloaded.
  • How to raise a car with a rack jack

    Rack jacks are similar in design to the HighJack. The main differences are the shorter length of the device and, as a result, the lifting height of the machine. Another important difference is that instead of a lever used in hijacks, the ascent and descent is controlled by a rotating handle. This design is more secure, as the double locking system of the handle ensures that it does not start to rotate unintentionally.

    To lift the machine:

    • make sure that all the requirements described above are met;
    • Check if the ground is firm where the heel of the jack will be. If you doubt its stability, it is necessary to place a support in the form of a plank or other solid material with an area larger than the heel of the jack;
    • the heel itself must be placed a few centimeters deeper than the plane of the body. This is necessary to securely lock the machine in the raised position. When lifting, the angle of inclination of the rack jack will be compensated;
    • Lifting and lowering the vehicle must be carried out smoothly, without sudden jerks or other movements that could impair the stability of the vehicle.

    How to use the HighJack correctly

    This type of jack is the most popular among SUV drivers. The answer to the question of how to use the hijack , is almost identical to the described rules for operating rack jacks. Safety Differences:
