Solution

1. Preparation

Gather tools and parts required for inspection and repair.
Park the vehicle on a flat surface and engage the parking brake.
Use jack stands to elevate the vehicle safely if necessary.

2. Inspect and Replace Suspension Components

Sub-steps:
1. Remove the wheel on the affected side using a socket set.
2. Inspect the strut assembly for any signs of leaking fluid or physical damage.
3. Check the control arm bushings for deterioration or excessive play.
4. If damaged, replace struts or control arms as necessary:
  - Remove the lower strut bolt and upper mount bolts.
  - Disconnect any connected sway bar links.
  - Install the new strut or control arm, securing with appropriate torque specifications (typically 40-60 ft-lbs for bolts).
5. Reassemble and torque all connections to manufacturer specifications.

3. Reinstall Wheel and Lower Vehicle

Sub-steps:
1. Place the wheel back onto the hub and hand-tighten lug nuts.
2. Lower the vehicle from the jack stands.
3. Use a torque wrench to tighten the lug nuts to the correct specifications (usually 80-100 ft-lbs).
