Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and securely lifted using jack stands.
Tools Required: Socket set, torque wrench, pry bar, stethoscope, jack, jack stands.

2. Inspect and Replace Worn Components

Sub-steps:
1. Remove the wheel of the affected side using a socket set.
2. Inspect the control arms, bushings, and ball joints for wear or damage. Replace any worn components.
  - Parts Required: Control arm, bushings, ball joint.
3. Check the shock absorbers and struts. If leaking or damaged, remove them by unbolting from the top and bottom mounts.
4. Install new shock absorbers or struts, ensuring they are torqued to manufacturer specifications.
  - Torque Value: Refer to the vehicle’s service manual for specific torque values.

3. Tighten Loose Fasteners

Sub-steps:
1. Inspect and retighten all suspension bolts and nuts to the specified torque settings.
2. Pay special attention to the control arm and sway bar links, as they often become loose.

4. Lubricate Moving Parts

Sub-steps:
1. Apply appropriate lubricant to all moving parts, including bushings and ball joints to eliminate squeaking noises.
