Solution

1. Preparation

Gather tools and parts needed for the strut replacement.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Safety warning: Disconnect the battery before working on any electrical components.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which struts require replacement.
Secure the vehicle on jack stands to ensure stability while you work.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel to access the strut assembly.

4. Disconnect the Strut

Remove any components obstructing the strut, such as brake lines or sway bar links.
Unbolt the strut from the lower control arm and the top mount located in the engine compartment or under the rear seat, depending on the type of strut.

5. Install New Strut

Position the new strut in place and secure it to the lower control arm and the top mount.
Torque the bolts to the manufacturer’s specifications (consult repair manual for exact torque values).

6. Reassemble and Lower Vehicle

Reattach any components removed earlier (brake lines, sway bar links).
Install the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and then torque the lug nuts to the specified value.
