Solution

1. Preparation

Gather necessary tools and parts.
Safely elevate the vehicle using a jack and secure it with jack stands.
Ensure the vehicle is on a level surface for accurate measurements.

2. Inspect Struts

Tools Required: Flashlight
Check the struts for visible signs of damage, such as dents or cracks.
Look for fluid leakage around the strut seals.

3. Replace Worn Struts

Tools Required: Socket set, torque wrench, strut spring compressor (if applicable)
Remove the wheel to access the strut assembly.
Disconnect the sway bar link (if equipped) and any brake line brackets attached to the strut.
Remove the strut assembly from the vehicle by unbolting it from the lower control arm and the top mount.
If necessary, use a strut spring compressor to safely remove the spring from the strut assembly.
Install the new struts (and springs if replaced) in reverse order. Ensure to torque all bolts to manufacturer specifications.

4. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Perform a test drive to verify stability and ride quality.
