Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent accidental electrical issues.

2. Remove Front Struts

Lift the front of the vehicle using a jack and secure it on jack stands.
Remove the front wheels using a socket set.
Detach the brake line bracket from the strut to prevent damage during removal.
Unbolt the strut from the steering knuckle using a socket wrench.
Remove the upper strut mount bolts from the engine compartment.
Carefully lower the strut assembly from the vehicle.

3. Inspect and Replace Struts

Examine the strut for leakage and physical damage.
If replacement is necessary, install new struts by reversing the removal steps.
Use a torque wrench to tighten the upper strut mount bolts to manufacturer specifications (typically around 25-30 Nm).
Reattach the strut to the steering knuckle, ensuring proper alignment.

4. Reassemble Vehicle

Reinstall the brake line bracket and ensure it is secure.
Reattach the front wheels and tighten lug nuts to manufacturer specifications (usually 110 Nm).
Lower the vehicle and reconnect the negative battery terminal.
