Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack stands, wheel chocks, impact wrench
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the battery to avoid any electrical issues during repair.

2. Raise the Vehicle

Loosen the lug nuts on the wheel associated with the strut being replaced.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel by fully taking off the lug nuts.

3. Remove the Strut Assembly

Tools Required: Spring compressor (if applicable), ratchet, and sockets
Locate and remove the lower strut bolts using the socket set.
Remove the upper strut mounting bolts in the engine bay or under the dashboard, depending on the model.
Carefully detach the strut from the vehicle. If the assembly is under tension, use a spring compressor to safely release tension before removing.

4. Install New Strut

Align the new strut with the mounting points and secure it in place with the upper and lower bolts.
Torque Specifications: Refer to the vehicle manual for the correct torque values for the strut bolts.
If using a spring compressor, ensure it is removed after the strut is securely installed.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and use the torque wrench to tighten the lug nuts to the manufacturer’s specifications.
Reconnect the battery and check for proper operation.
