Solution

1. Preparation

Tools Required: Socket set, torque wrench, spring compressor, impact wrench, flathead screwdriver, pry bar, jack stands, floor jack.
Raise the vehicle using a floor jack and secure it on jack stands.
Remove the wheel corresponding to the strut being replaced.

2. Remove the Strut Assembly

Disconnect the sway bar link: Use a socket to remove the nut securing the sway bar link to the strut.
Remove the brake line bracket: Unscrew the bolt securing the brake line to the strut using a socket.
Loosen the strut top mount bolts: Open the hood and locate the strut top mount. Use a socket to loosen the three bolts holding it in place, but do not remove them completely.
Disconnect the lower strut mounting bolts: At the bottom of the strut, remove the two bolts using a socket and impact wrench to free the strut from the knuckle.
Remove the strut from the vehicle: After loosening the top mount bolts fully, carefully pull the strut assembly out from the wheel well.

3. Replace the Strut

Compress the coil spring: Using a spring compressor, carefully compress the spring to relieve tension before removing the top mount.
Remove the top mount: Unscrew the three bolts and gently remove the top mount from the old strut.
Install the top mount on the new strut: Position the top mount onto the new strut and secure it with the three bolts.
Remove the spring compressor: Slowly release the tension on the spring compressor, ensuring that the spring is seated properly on the new strut.

4. Install the New Strut Assembly

Position the new strut: Insert the new strut into the wheel well, aligning it with the knuckle.
Reconnect the lower strut mounting bolts: Insert the bolts and tighten them to the manufacturer’s torque specifications.
Reconnect the sway bar link and brake line bracket: Secure both components back in place using the appropriate bolts.
Tighten the top mount bolts: Go back to the engine bay and tighten the three bolts holding the top mount to the manufacturer’s torque specifications.

5. Reassemble and Test

Reattach the wheel: Mount the wheel back onto the hub and tighten the lug nuts to the manufacturer’s specifications.
Lower the vehicle: Carefully remove the jack stands and lower the vehicle to the ground.
Check alignment: It is recommended to have the vehicle's alignment checked post-installation.
