Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Socket set
- Torque wrench
- Strut spring compressor (if replacing struts)
- Safety glasses and gloves
Park on a level surface and ensure the vehicle is in "Park" mode.

2. Raise the Vehicle

Use the jack to lift the vehicle at the designated lift points.
Secure the vehicle with jack stands to ensure safety.

3. Remove Wheel

Using a socket set, remove the lug nuts and take off the front or rear wheel, depending on which strut you are replacing.

4. Remove the Strut

Disconnect Components: Remove any components obstructing the strut (e.g., brake lines, sway bar links) using the appropriate socket sizes.
Remove Strut Mount Bolts: Locate and remove the strut mount bolts at the top of the strut assembly.
Detach the Strut: Remove the lower strut bolts and carefully detach the strut from the suspension.
Inspect the Strut: Check for any signs of wear or damage on the strut assembly itself.

5. Install New Strut (if necessary)

Prepare New Strut: If replacing, use a strut spring compressor to install the spring onto the new strut according to the manufacturer’s specifications.
Position the New Strut: Align the new strut in the suspension assembly and secure it with the lower and upper bolts.
Torque Specifications: Use a torque wrench to tighten all bolts to the manufacturer’s specifications.

6. Reassemble Components

Reattach any components that were disconnected during the removal process.
Ensure everything is properly secured and torqued.

7. Replace Wheel and Lower Vehicle

Reinstall the wheel and tighten the lug nuts in a star pattern.
Carefully lower the vehicle back to the ground.
