Using a lug wrench, loosen the lug nuts on the wheel associated with the leaking strut.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the strut.

3. Remove Strut Assembly

Locate the strut mounting bolts on the top of the strut tower and the bottom of the knuckle.
Remove the top strut tower bolts using a socket wrench (torque specifications may vary; refer to the service manual).
Remove the bottom strut bolt using a socket wrench (check for torque specifications).
Carefully detach the strut from the knuckle and remove it from the vehicle.

4. Replace Strut

Install the new strut by reversing the removal steps.
Align the strut into the knuckle and secure it with the bottom bolt, tightening to manufacturer specifications.
Secure the top of the strut to the strut tower with the bolts, ensuring proper alignment.

5. Reinstall Wheel and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and fully tighten the lug nuts in a crisscross pattern to ensure even pressure.
