Tools and Materials Needed:
- Jack and jack stands
- Socket wrench set
- Combination wrench set
- Strut spring compressor
- New struts (front or rear-specific)
- Strut mount kit (if necessary)
- Anti-seize lubricant
Step-by-Step Guide:
1. Prepare the Vehicle:
- Park the vehicle on a level surface and apply the parking brake.
- Loosen the lug nuts of the rear wheels but don't remove them completely.
2. Lift the Vehicle:
- Use a jack and jack stands to lift the rear of the vehicle, starting with one side.
- Once the wheel is off the ground, remove the lug nuts and the wheel to gain access to the strut assembly.
3. Remove the Top Mount:
- Open the trunk or rear hatch and remove any covers exposing the top of the strut assembly.
- Locate the three nuts securing the top mount of the strut to the vehicle's body.
- Use a socket wrench to remove these nuts.
Note: It may be necessary to use a breaker bar to loosen the nuts if they are tight.
4. Compress the Spring:
- Install a strut spring compressor around the strut assembly to compress the spring.
- Refer to the specific strut spring compressor instructions for proper usage and safety precautions.
- Compress the spring until the tension is released, allowing the strut to extend fully.
5. Disconnect the Brake Line:
- Locate the brake line connected to the strut assembly near the bottom.
- Use a combination wrench to disconnect the brake line.
Note: Have a catch pan ready to collect any leaking brake fluid.
6. Disconnect the Sway Bar:
- If equipped, locate and remove the bolts or nuts that connect the sway bar link to the strut assembly.
7. Remove the Strut:
- Use a socket wrench to remove the bolts securing the bottom of the strut to the vehicle's suspension components.
- Once all bolts are removed, carefully remove the strut assembly.
8. Install the New Strut:
- Position the new strut in place, aligning the mounting holes.
- Install the bolts or nuts removed earlier to secure the strut to the vehicle's suspension.
- Be sure to apply anti-seize lubricant to the bolts to prevent future corrosion.
9. Reconnect the Sway Bar (if applicable):
- If equipped, reattach the sway bar link to the new strut.
10. Reconnect the Brake Line:
- Reconnect the previously disconnected brake line to the strut assembly.
- Ensure the brake line is securely tightened to prevent leaks.
11. Reinstall the Top Mount:
- Place the new strut mount on top of the strut.
- Install the three nuts removed in Step 3 to secure the top mount.
12. Decompress the Spring:
- Slowly release the strut spring compressor, allowing the spring to settle back into place.
- Follow proper safety precautions during decompression.
13. Reinstall the Wheel:
- Place the wheel back on the vehicle and install the lug nuts.
14. Lower the Vehicle:
- Carefully lower the vehicle using the jack and jack stands.
15. Tighten the Lug Nuts:
- Fully tighten the lug nuts using a star pattern in several increments.
16. Repeat for the Other Side (if applicable):
- If you're replacing both rear struts, repeat Steps 2-16 for the other side.
Remember that this guide provides a general overview, and specific steps and procedures may vary depending on your exact model and trim level. If you're unsure or uncomfortable with any of the steps, it's best to consult the vehicle's service manual or seek assistance from a qualified mechanic.
