Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear appropriate safety gear, including gloves and safety glasses.

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove the Strut Assembly

Disconnect any brake lines or sensors attached to the strut assembly (if applicable).
Remove the bolts securing the strut to the steering knuckle using a socket and ratchet.
Remove the upper strut mounting bolts located under the hood or in the cabin, ensuring you have access to the strut tower.
Carefully pull the strut assembly out of its position.

4. Inspect and Replace

Inspect the old strut for signs of wear, including leaks or damage.
If replacement is necessary, install the new strut by reversing the removal process:
- Position the new strut into the strut tower and secure it with the upper mounting bolts.
- Reattach the strut to the steering knuckle with the previously removed bolts.
- Ensure all connections are tight and secure.

5. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle to the ground and use a torque wrench to tighten the lug nuts to the manufacturer’s specifications (usually around 76 lb-ft for Tacoma).
Reconnect any brake lines or sensors that were disconnected.

6. Final Inspection

Double-check all bolts and connections.
Test the vehicle to ensure proper handling and comfort.
