Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical issues.
Use wheel chocks to secure the vehicle.

2. Remove the Wheel

Using a lug wrench, loosen the lug nuts on the wheel corresponding to the leaking strut.
Lift the vehicle with a jack and support it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove the Strut Assembly

Locate and remove the top strut mounting bolts under the hood (may require removing the engine cover).
Disconnect the lower strut mounting bolts from the knuckle using a socket and ratchet.
Carefully detach any brake lines or sensors connected to the strut.
Remove the strut assembly from the vehicle.

4. Inspect and Replace

Inspect the strut for leaks and physical damage.
If the strut is indeed leaking, replace it with a new strut specific to the Toyota Camry XV70.
If necessary, replace the strut mounts and any other worn components.

5. Reinstall Strut Assembly

Position the new strut assembly in place and secure it to the knuckle with lower mounting bolts.
Reattach the top strut mounting bolts and torque them to the manufacturer's specifications (typically 30-40 ft-lbs).
Reconnect any brake lines or sensors that were previously detached.

6. Reinstall the Wheel

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then torque the lug nuts to the manufacturer's specifications (typically 76-86 ft-lbs).

7. Final Checks

Reconnect the battery.
Perform a visual inspection to ensure everything is secured properly.
