Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Use wheel chocks to prevent the vehicle from rolling.

2. Remove Wheel

Loosen the lug nuts on the front or rear wheel where the strut is to be replaced using a lug wrench.
Raise the vehicle using a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Strut Assembly

Locate the strut assembly and identify the upper strut mount bolts and lower strut bolts.
Using a socket set, remove the upper strut mount bolts from the engine bay or under the rear seat, depending on the strut's location.
Remove the lower strut bolts using an impact wrench or ratchet, ensuring the suspension is supported.
Carefully maneuver the strut assembly out of its housing.

4. Install New Strut

Position the new strut in place, aligning it with the lower mounting points first.
Insert and hand-tighten the lower strut bolts.
Reattach the upper strut mount by tightening the bolts securely to the manufacturer’s specified torque value.
Ensure the strut is properly seated and aligned.

5. Reassemble Vehicle

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands using the jack.
Tighten the lug nuts to the manufacturer’s specified torque value in a star pattern for even distribution.

6. Final Checks

Inspect for any loose connections or misalignments.
Verify that the strut is functioning properly by performing a bounce test again.
