Diagnostic Steps

1
Visually inspect the struts for signs of oil leakage or physical damage.

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Use jack stands to secure the vehicle after lifting.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Remove the wheel to access the strut assembly.

3. Disconnect Strut Components

Remove the brake line bracket attached to the strut.
Detach the sway bar link from the strut using a socket wrench.
Unbolt the strut from the steering knuckle at the bottom and the strut mount at the top.

4. Install New Strut

Position the new strut assembly in place.
Secure it to the steering knuckle and the strut mount using the appropriate torque specifications (typically 30-40 ft-lbs for the top mount and 80-100 ft-lbs for the lower mount).
Reattach the sway bar link and brake line bracket to the new strut.

5. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically 100-130 ft-lbs).

6. Final Checks

Check the alignment of the wheels after strut replacement to ensure proper handling and tire wear.
