If a specific component is identified (e.g., control arm, strut, or bushing), proceed to remove it:
- Control Arm:
  1. Remove the wheel using a socket set.
  2. Disconnect the control arm from the chassis and hub using appropriate socket sizes.
- Shock Absorber:
  1. Detach the top and bottom mounting bolts.
  2. Remove the shock absorber from the vehicle.

4. Replace Worn Components

Install new parts as required:
- Replace worn bushings or strut mounts.
- Install new shock absorbers or control arms as needed.
Ensure all components are torqued to manufacturer specifications (refer to a service manual for specific torque values).
