Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Raise the Vehicle

Use a floor jack to lift the vehicle and support it with jack stands.
Remove the wheels to gain access to the struts.

3. Remove the Struts

Tools Required: Socket set, wrench set, strut spring compressor.
Remove the strut mounting bolts from the top of the strut tower and the lower control arm.
Carefully detach any brake lines or sensors attached to the strut.
Use the strut spring compressor to safely compress the coil spring, then remove the top strut nut to separate the strut from the spring.

4. Inspect and Replace Components

Inspect the strut assembly, including the coil spring, for signs of wear or damage.
If replacement is needed, install the new strut into the coil spring and secure it with a new top strut nut, torquing to manufacturer's specifications.

5. Reinstall Struts

Reattach the strut to the lower control arm and secure with bolts, torquing to specified values.
Reconnect any brake lines or sensors that were detached.

6. Lower the Vehicle

Replace the wheels and lower the vehicle back to the ground.
Reconnect the battery.
