Car fell off jack while changing tire – this can be extremely dangerous and may cause injury or vehicle damage. If the car falls off the jack, do not crawl under it; instead, safely reposition the jack on a solid, level surface and use wheel chocks for added stability before lifting again.
Changing a flat tire is one of the most common car maintenance tasks that every driver should be familiar with. However, mishaps such as a car falling off the jack can occur if proper precautions are not taken. It’s not only alarming but also potentially damaging to the vehicle. A jack is designed to lift the car safely, but a sudden shift or improper setup can lead to the jack slipping, causing the vehicle to fall. If this happens, it could result in suspension damage, body damage, or, in some cases, injury.
In this detailed guide, we will explain the reasons why a car might fall off the jack, immediate steps to take if it happens, and preventive measures to ensure safe tire changes every time.

What Causes a Car to Fall Off the Jack?
It is important to know why a car may fall off the jack is the first step in preventing it from happening. There are several factors involved in ensuring the stability of the car on the jack.
1. Incorrect Jack Placement
One of the most common reasons a car may fall off the jack is improper placement. Every vehicle has specific jacking points where the jack should be placed, and it’s important to follow these guidelines. If the jack is placed on an unsupported or inappropriate area of the car, it may fail to provide the necessary support, leading to instability. Always consult the vehicle’s owner’s manual for proper jacking points, which are usually located near the vehicle’s frame or rocker panels.
2. Using the Wrong Type of Jack
Another reason why cars fall off jacks is using the wrong type of jack for the vehicle’s weight. For example, a small, lightweight floor jack might not have the lifting capacity required to safely lift a larger vehicle, which could cause the jack to collapse under pressure. Using a jack rated for a vehicle’s weight capacity ensures a safer lift. Always check the jack’s weight limit to ensure it’s suitable for the car.
3. Unstable or Uneven Ground
The surface you’re working on plays a significant role in ensuring the car remains stable on the jack. If you’re working on soft soil, gravel, or an inclined surface, the jack may sink or tip over. It’s essential to position the car on a flat, solid surface, like concrete, to prevent instability. If you must work on a soft surface, consider using a jack pad or plywood under the jack’s base to provide better support.
4. Not Using Jack Stands
While a jack can lift the car, it is not designed to hold the vehicle in place for an extended period. Jack stands are necessary for securely supporting the car once it is lifted. Without jack stands, you are relying solely on the jack, which can fail, leading to the vehicle falling. Always place jack stands under the vehicle after lifting it to ensure it is securely supported during the tire change.
5. Vehicle Not in Park or Gear
If you fail to engage the parking brake or put the vehicle in gear (for manual transmission cars), the car can shift during the jacking process, causing the jack to become unstable. Always ensure the parking brake is engaged and, for manual cars, the car is in gear before lifting it with the jack. This step helps prevent the vehicle from moving while you are changing the tire.
6. Overloading the Jack
Most jacks come with a weight limit. Overloading the jack, by attempting to lift a car that exceeds its maximum weight capacity, can cause the jack to fail. It’s important to know the car’s weight and use a jack that can safely handle it. Be sure to check the jack’s specifications before using it.
Immediate Actions to Take if the Car Falls Off the Jack
If a car falls off the jack while changing the tire, it’s crucial to stay calm and take immediate action. Here’s what you should do:
1. Ensure Personal Safety
Safety is the number one priority. Immediately move away from the vehicle and make sure no one is in harm’s way. If you were under the vehicle or close to it when it fell, carefully assess whether you or anyone else is injured. If someone is injured, call for medical help immediately.
2. Stabilize the Vehicle
If the car is still partially raised and stable, do not attempt to reposition it without proper equipment. First, place wheel chocks or large blocks under the tires to prevent the car from rolling further. This will help prevent additional movement while you assess the situation.
3. Inspect the Damage
Before trying to lift the car again, carefully inspect both the vehicle and the jack for any signs of damage. Look for any signs of structural or body damage to the car, especially around the jacking points and suspension. If there’s any significant damage, such as bent metal or leaking fluids, it may be necessary to have the vehicle checked by a professional mechanic.
4. Reposition the Jack
Once the car is stabilized, use a jack again to lift the car, but this time ensure that it is correctly placed under the proper jacking point. If the jack is faulty or unstable, replace it with a safer, more robust jack. Be sure the ground is stable before lifting the car.
5. Use Jack Stands
Always use jack stands to support the vehicle once it is raised. Jack stands are designed to hold the weight of the vehicle safely, preventing accidents during the tire change. Never attempt to work on a car supported only by a jack, as this is extremely unsafe.
How to Avoid Future Incidents
The best way to deal with a car falling off the jack is to prevent it from happening in the first place. Here are some preventive measures you can take:
1. Double Check the Jack Placement
Always verify that the jack is placed under the correct jacking points. The wrong placement could cause the jack to slip or fail. Additionally, check that the jack is securely positioned on a flat, stable surface. If you’re working in an area with soft soil or gravel, use a large piece of wood or a jack pad to provide additional stability.
2. Use Proper Equipment
Invest in a high-quality, heavy-duty jack and jack stands that are rated for the weight of the vehicle. Never use a jack that has been damaged or is rated for a lighter vehicle than yours. Using the right equipment is key to a safe tire change.
3. Engage the Parking Brake and Put the Car in Gear
Before you lift the car, always ensure that the parking brake is engaged, and the car is in gear (for manual transmission) or in “Park” (for automatic transmission). This will prevent the car from rolling while you work.
4. Work on a Flat, Stable Surface
Avoid working on an incline or uneven ground. Always change the tire on a flat, solid surface like asphalt or concrete. If you have no other option, place sturdy boards under the tires to give the jack a more stable surface.
5. Don’t Rely Only on the Jack
Once the vehicle is raised, always use jack stands to secure it. Jack stands are specifically designed to support the car and hold its weight while you work. Never rely solely on the jack to hold the car.
Frequently Asked Questions
Here are some FAQs about fell off jack while changing tire –
Can a car’s suspension be damaged if it falls off the jack?
Yes, falling off the jack can damage the suspension components, undercarriage, and possibly cause alignment issues. It’s essential to inspect the vehicle for any visible damage before attempting to drive it.
How do I know if my jack is safe to use?
Check for any signs of wear, such as leaks, rust, or uneven lifting. Always use a jack rated for your vehicle’s weight and ensure it’s in good working condition before use.
How long can I leave a car on a jack without jack stands?
You should never leave a car on a jack without jack stands. A jack is designed only to lift the vehicle, not to hold it up for an extended period. Always use jack stands for safety.
Can I use a small car jack for a larger vehicle?
No, using a small jack for a larger vehicle can be dangerous. Always use a jack rated for your vehicle’s weight. Using the wrong jack can cause it to fail or collapse under pressure.
Conclusion
Changing a tire is an essential skill for any driver, but it’s important to understand the proper procedures to ensure your safety.
