Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on which strut is leaking.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Use a lug wrench to remove the lug nuts.
Take off the wheel to access the strut assembly.

4. Disconnect Strut from Mounting Points

Top Mount:
- Locate the top strut mount under the hood.
- Remove any covers if necessary and use a socket to remove the nuts securing the strut to the mount.
Bottom Mount:
- Locate the bolts securing the strut to the lower control arm.
- Use a socket or wrench to remove these bolts.

5. Remove the Strut Assembly

Carefully remove the strut from the vehicle, taking care to not damage surrounding components.

6. Install New Strut

Position the new strut in place, ensuring it aligns correctly with the mounting holes.
Install the bottom bolts first and torque them to the manufacturer’s specifications (typically around 80-90 ft-lbs).
Reattach the top mount and secure it with the nuts, again torquing them according to specifications (usually around 25-30 ft-lbs).

7. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Use a torque wrench to tighten the lug nuts to the manufacturer’s specifications (generally 100-150 ft-lbs).

8. Lower Vehicle and Test

Remove the jack stands and lower the vehicle using the hydraulic jack.
Test drive the vehicle to ensure proper function and check for any leaks.
