The vehicle jack is one of the most important but often overlooked tools in your car. It plays a critical role during tire changes, maintenance work, or emergency roadside situations. Knowing how to use a jack safely and understanding the proper methods of jack stowage can save time and help avoid injuries or damage to your vehicle. Despite being simple in design, the jack requires respect and knowledge to operate properly. This topic explores the various types of jacks, safe usage techniques, and essential jack stowage practices every vehicle owner should know.
Types of Vehicle Jacks
Scissor Jack
This is the most common type found in passenger cars. It uses a mechanical screw mechanism to lift the vehicle. Scissor jacks are compact and lightweight, making them ideal for emergency use.
Hydraulic Bottle Jack
Often found in trucks or SUVs, this jack uses hydraulic force to lift heavier vehicles. It has a cylindrical shape resembling a bottle and provides greater lifting power than a scissor jack, although it takes up more space.
Hydraulic Floor Jack
Common in garages and repair shops, the floor jack is easy to use and allows for fast lifting. While not ideal for stowage in your vehicle due to its bulk, it offers excellent stability and precision.
Hi-Lift Jack
Mostly used for off-road vehicles, this jack can lift vehicles much higher than standard jacks. It’s useful in uneven terrain but requires more skill and caution to operate safely.
Steps for Safe Jack Usage
Preparation Before Jacking
- Ensure the vehicle is on a flat, stable surface. Avoid soft or uneven ground.
- Apply the parking brake and shift into gear or park mode.
- Turn off the engine and keep all passengers out of the vehicle.
- Place wheel chocks on the opposite side of the car to prevent rolling.
Locating the Jack Points
Each vehicle has specific jacking points, usually indicated in the owner’s manual. These points are reinforced areas designed to handle the load. Using incorrect locations can damage the vehicle or cause the jack to slip.
Raising the Vehicle
- Position the jack under the correct jack point.
- Begin raising the vehicle slowly and steadily.
- Lift only high enough to perform the required task, such as changing a tire.
- Never crawl under a car supported only by a jack always use jack stands if extended time under the vehicle is required.
Lowering the Vehicle
Once the task is complete, lower the vehicle slowly. Ensure no tools or limbs are underneath. Turn the jack handle counterclockwise or release the hydraulic valve carefully, depending on the jack type.
Safety Tips for Using a Jack
- Inspect the jack before use. Do not use if it’s rusty, leaking, or damaged.
- Never exceed the jack’s weight limit, which is usually indicated on the tool.
- Use a jack pad or wood block for extra stability on soft surfaces.
- Do not use a jack in windy or unstable weather conditions if avoidable.
- Always read and follow the manufacturer’s instructions.
Proper Jack Stowage
Why Jack Stowage Matters
Improper jack storage can cause damage to your vehicle or become a safety hazard during a collision or sharp maneuver. Keeping your jack clean, secure, and accessible ensures it will be ready when needed.
Factory-Installed Storage
Most vehicles come with a designated compartment for jack storage, usually in the trunk or under a panel. Always return the jack to this location after use. It is often paired with the spare tire and lug wrench.
Securing Aftermarket Jacks
If you use a larger jack not supplied with your vehicle, like a hydraulic bottle jack or hi-lift jack, secure it using heavy-duty straps or mounts. Off-roaders often install special brackets in the cargo area or roof racks for stowing larger jacks safely.
Keep It Clean and Maintained
- Wipe off dirt and grease after each use.
- Store in a dry area to avoid rust.
- Oil the screw or hydraulic parts occasionally to keep it functional.
Other Tools to Store With a Jack
Your jack is part of a larger emergency toolkit. Keep the following items nearby:
- Spare Tire: Fully inflated and in good condition.
- Lug Wrench: Correct size for your wheel nuts.
- Flashlight: For night-time emergencies.
- Gloves: To protect your hands during operation.
- Wheel Chocks: Prevent vehicle movement.
Common Mistakes to Avoid
Using a Jack on an Incline
Attempting to use a jack on a hill or sloped surface increases the risk of vehicle slippage. Always find a flat, stable spot or call for professional help if unavailable.
Ignoring Jacking Points
Lifting the car from an improper location can damage the frame or underbody components. Use only the marked jacking points in your owner’s manual.
Overloading the Jack
Never attempt to lift more than the rated capacity of your jack. This can lead to sudden jack failure and serious injury.
Understanding jack usage and jack stowage is essential for all drivers. Whether you’re a daily commuter or a weekend road tripper, knowing how to safely use and store a jack could be a lifesaver. From scissor jacks to hydraulic options, each type has its use case, and learning the proper techniques ensures you’re prepared for emergencies. Don’t wait for a flat tire to discover you’ve stored your jack improperly or don’t know how to use it. Take the time now to familiarize yourself with your vehicle’s equipment. It’s a small investment in time that can make a big difference when it counts most.
