Installing adjustable control arms on your Nissan 240SX can significantly improve handling and suspension geometry. This guide will walk you through the process step-by-step, ensuring a smooth installation.

Tools and Materials Needed

Before starting the installation, gather the necessary tools and materials:

  • Adjustable control arms
  • Jack and jack stands
  • Socket set
  • Wrench set
  • Torque wrench
  • Grease
  • Safety glasses
  • Work gloves

Preparation

Before you begin the installation, ensure your vehicle is parked on a flat surface. Engage the parking brake and wear safety glasses and gloves for protection.

Step 1: Lift the Vehicle

Using a jack, lift the front or rear of the vehicle, depending on which control arms you are replacing. Secure the vehicle with jack stands to ensure stability.

Step 2: Remove the Wheels

Remove the lug nuts with a socket wrench and take off the wheels to access the suspension components.

Removing Stock Control Arms

With the wheels removed, you can now access the stock control arms. Follow these steps to remove them:

Step 3: Disconnect the Stock Control Arms

Locate the bolts securing the stock control arms to the chassis and the knuckle. Use a socket set to remove these bolts. Keep these bolts, as you may need them for the adjustable control arms.

Step 4: Remove the Control Arms

Once the bolts are removed, carefully take out the stock control arms. You may need to wiggle them free, as they can be tight due to corrosion or debris.

Installing Adjustable Control Arms

Now that the stock control arms are removed, it’s time to install the adjustable control arms. Follow these steps:

Step 5: Position the Adjustable Control Arms

Align the adjustable control arms with the mounting points on the chassis and knuckle. Ensure that the arms are oriented correctly as per the manufacturer’s instructions.

Step 6: Secure the Control Arms

Insert the bolts you previously removed into the adjustable control arms. Use a torque wrench to tighten them to the manufacturer’s specifications. This ensures they are secure and will not come loose during operation.

Final Steps

With the adjustable control arms installed, follow these final steps to complete the installation:

Step 7: Reinstall the Wheels

Place the wheels back onto the hub and hand-tighten the lug nuts. Once all wheels are in place, lower the vehicle back to the ground.

Step 8: Torque the Lug Nuts

Once the vehicle is on the ground, use a torque wrench to tighten the lug nuts to the manufacturer’s specifications to ensure they are secure.

Step 9: Adjust Control Arms

Before driving, adjust the control arms to the desired specifications. This may require a professional alignment to ensure optimal handling and performance.

Conclusion

Installing adjustable control arms on your 240SX can enhance your vehicle’s performance and handling. By following this step-by-step guide, you can complete the installation with confidence. Always remember to check your alignment after making suspension modifications to ensure the best driving experience.
