Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, strut spring compressor (if replacing struts), and a fluid catch pan.
Ensure the vehicle is on a level surface and the parking brake is engaged.

2. Lift the Vehicle

Loosen the lug nuts on the front wheels with a lug wrench.
Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels.

3. Remove the Struts

Upper Mount: Locate the upper strut mount inside the engine bay or under the dash, depending on the design. Remove the bolts using a socket set.
Lower Mount: Remove the bolts from the lower strut mount connected to the steering knuckle.
Disconnect Components: If necessary, disconnect any brake line clips or sway bar links attached to the strut.
Carefully remove the strut assembly from the vehicle.

4. Replace or Repair Struts

Inspect Strut: If the strut is leaking, it needs to be replaced. Use a strut spring compressor to safely remove the spring from the strut.
Install New Strut: If replacing, install the new strut assembly by reversing the disassembly steps. Ensure the strut is positioned correctly and properly aligned with the mount holes.
Torque Specifications: Tighten all mounting bolts to the manufacturer’s specified torque settings.

5. Reassemble and Lower the Vehicle

Reattach the wheels and hand-tighten the lug nuts.
Lower the vehicle back to the ground using the jack.
Once on the ground, torque the lug nuts to the manufacturer’s specifications.

6. Final Inspection

Check for any fluid leaks around the new struts.
Ensure everything is tightened and secure.
