1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use jack stands for safety if raising the vehicle.

2. Inspect and Replace Struts/Shocks

Sub-steps:
1. Remove the wheel to access the strut assembly.
2. Unbolt the strut from the top mount and lower mount (torque specifications: top mount 15-20 ft-lbs, lower mount 40-50 ft-lbs).
3. Remove the strut and inspect for leaks or damage.
4. Install new strut/shock following manufacturer instructions and torque specifications.
5. Reattach the wheel and lower the vehicle.

3. Replace Sway Bar Links

Sub-steps:
1. Locate the sway bar links on both sides of the vehicle.
2. Use a wrench to unbolt the sway bar links (torque specifications: 30-40 ft-lbs).
3. Inspect the sway bar links for wear or looseness and replace if necessary.
4. Install the new sway bar links and torque to specifications.

4. Inspect and Replace Control Arms/Bushings

Sub-steps:
1. Check the control arms for cracks or bent structure.
2. Use a wrench to unbolt the control arm from the subframe (torque specifications: 60-70 ft-lbs).
3. Inspect and replace the bushings if they appear cracked or worn.
4. Reinstall the control arm and torque bolts to specifications.
