Solution

1. Preparation

Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Gather tools and parts required for the repair.

2. Inspect and Replace Suspension Components

Inspect the Shocks/Struts:
- Check for fluid leakage around the struts/shocks.
- If damaged, proceed to replace.
Replace Worn Struts/Shocks:
- Tools Required: Socket set, torque wrench, spring compressor (if necessary).
- Sub-steps:
  1. Remove the wheel on the affected side using a socket set.
  2. Disconnect the upper and lower mounting bolts of the shock/strut assembly.
  3. If applicable, use a spring compressor to safely remove the coil spring from the strut assembly.
  4. Install the new strut/shock and reassemble in reverse order, making sure to torque bolts to manufacturer specifications.

3. Inspect and Replace Sway Bar Links

Inspect the Sway Bar Links:
- Check for any play or damage in the sway bar links.
Replace Sway Bar Links if Necessary:
- Tools Required: Ratchet, socket set, torque wrench.
- Sub-steps:
  1. Remove the sway bar link from the sway bar and the lower control arm.
  2. Install the new sway bar link and tighten to the manufacturer’s torque specifications.

4. Final Inspection

Check all mounting hardware and components to ensure they are secure and correctly installed.
Reinstall the wheels and lower the vehicle.
