1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, stable surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during maintenance.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle.
Secure the vehicle with jack stands to ensure safety while working underneath.

3. Remove the Strut Assembly

Tools Required: Socket set, torque wrench, strut spring compressor.
Remove the wheel by loosening the lug nuts and taking off the tire.
Detach the sway bar link from the strut if applicable.
Unbolt the strut from the lower control arm and upper mount.
Carefully remove the strut assembly from the vehicle.

4. Inspect and Replace

Inspect the strut for leaks, physical damage, or unusual wear.
If worn, use a strut spring compressor to safely remove the coil spring from the strut.
Install a new strut or rebuild the existing one with new components if applicable.
Ensure all rubber bushings are in good condition, replacing them if necessary.

5. Reinstall the Strut Assembly

Reinstall the strut assembly back into the vehicle.
Bolt it to the lower control arm and upper mount, tightening to the manufacturer's specified torque settings.
Reattach the sway bar link if it was removed.
