Understanding Struts and Their Function
Before diving into the removal process, it’s essential to understand the role struts play in your car’s suspension system. Struts are telescopic shock absorbers that combine the functions of a shock absorber and a spring. They are responsible for:
* **Absorbing shocks:** Struts dampen the impact of bumps and dips in the road, providing a smoother ride and protecting your vehicle’s components from excessive stress.
* **Maintaining tire contact:** Struts help keep your tires firmly planted on the road surface, ensuring optimal grip and handling, especially during cornering or braking.
* **Supporting vehicle weight:** Struts contribute to the overall structural integrity of your car by supporting its weight and helping to maintain proper ride height.
Different types of struts exist, including MacPherson struts, double wishbone struts, and coil-over struts. Each type has its own design and characteristics, but the fundamental function remains the same: to provide a smooth and controlled ride while maintaining stability and handling.
Tools and Safety Precautions
Before you begin removing struts, gather the necessary tools and prioritize safety.
Tools Required:
- Jack and jack stands: Essential for safely lifting your vehicle and supporting its weight.
- Lug wrench: To remove the lug nuts from the wheels.
- Wrench set: Various sizes will be needed to loosen and tighten bolts.
- Socket set: For accessing bolts in tight spaces.
- Breaker bar: Provides extra leverage for stubborn bolts.
- Torque wrench: To tighten bolts to the manufacturer’s specifications.
- C-clamp or strut compressor: To compress the strut assembly for removal.
- Penetrating oil: To loosen rusted or seized bolts.
- Safety glasses and work gloves: Protect your eyes and hands from debris and sharp edges.
Safety Precautions:
- Always work on a level surface and engage the parking brake before lifting your vehicle.
- Never work under a vehicle supported only by a jack. Use jack stands for secure support.
- Wear safety glasses and work gloves to protect yourself from injury.
- Disconnect the negative battery terminal before working on any electrical components.

Removing the Struts
Once you have the necessary tools and safety precautions in place, you can begin the strut removal process. The specific steps may vary slightly depending on your vehicle model, but the general procedure is as follows:
1. Loosen Lug Nuts:
Before jacking up the vehicle, use the lug wrench to loosen the lug nuts on the wheel where you will be removing the strut. Do not remove them completely at this stage. (See Also: How to Remove the Scratch from Car? Easy Fix Guide)
2. Lift and Secure the Vehicle:
Position the jack under the designated jacking point for your vehicle (refer to your owner’s manual). Slowly raise the vehicle until the wheel is off the ground. Securely place jack stands under the designated support points to safely support the vehicle’s weight.
3. Remove the Wheel:
Now, completely remove the lug nuts and carefully take off the wheel. Set it aside in a safe location.
4. Disconnect Suspension Components:
Identify and disconnect the various suspension components connected to the strut, such as the control arms, sway bar links, and brake lines. Use the appropriate wrenches or sockets to loosen and remove the bolts. Take note of the order and orientation of these components for easier reinstallation.
5. Remove the Strut Mounting Bolts:
Locate the bolts securing the strut to the vehicle’s chassis or strut tower. These bolts may require a breaker bar for extra leverage. Remove the bolts carefully, and set them aside in a safe place.
6. Compress the Strut Assembly:
With the strut mounting bolts removed, you can now compress the strut assembly using a C-clamp or a strut compressor. This will allow you to remove the strut from the vehicle. Follow the manufacturer’s instructions for your specific strut compressor.
7. Remove the Strut:
Once the strut is compressed, carefully remove it from the vehicle. Be mindful of any remaining components or wiring connected to the strut.
Installing New Struts
After removing the old struts, you’ll need to install new ones. This process is essentially the reverse of the removal procedure, but it’s important to follow the correct steps and torque specifications to ensure a safe and secure installation.
1. Prepare the New Struts:
Inspect the new struts for any damage or defects. Ensure that all components are present and in good condition. Apply a thin layer of grease to the strut shaft and any rubber seals to prevent friction and wear.
2. Install the Strut:
Align the new strut with the mounting points on the vehicle’s chassis or strut tower. Carefully insert the strut into place, ensuring that it is properly seated. (See Also: How to Remove Plastic Scratches from Car? Easy Fixes)
3. Tighten Mounting Bolts:
Install the mounting bolts and tighten them to the manufacturer’s specified torque. Use a torque wrench to ensure that the bolts are tightened to the correct specifications.
4. Reconnect Suspension Components:
Reconnect all the suspension components that were disconnected during the strut removal process, such as the control arms, sway bar links, and brake lines. Tighten all bolts to the manufacturer’s specifications.
5. Reinstall the Wheel:
Place the wheel back onto the hub and tighten the lug nuts by hand. Lower the vehicle using the jack and then fully tighten the lug nuts in a star pattern using the lug wrench.
6. Lower the Vehicle:
Carefully lower the vehicle using the jack until the jack stands are no longer supporting the vehicle’s weight. Remove the jack stands.
7. Test Drive:
Before driving your vehicle, double-check all connections and ensure that the lug nuts are securely tightened. Take your vehicle for a test drive to ensure that the new struts are functioning properly and that the ride height is correct.
