Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical issues during repairs.

2. Inspect and Remove Components

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheel on the affected side for better access to the suspension components.
- Check the shock absorbers and struts for leaks or damage.
- Remove any components that may obstruct access to the bushings or mounts, such as the sway bar or control arms.

3. Replace Worn Components

Sub-steps:
- If any bushings, mounts, or shock absorbers are found defective, replace them with new parts.
- For shock absorbers, ensure the correct orientation and position of the new units.
- Torque bolts to manufacturer specifications (consult the service manual for specific torque values).

4. Reassemble and Lower Vehicle

Sub-steps:
- Reattach all removed components in reverse order.
- Ensure all fasteners are tightened to the proper torque specifications.
- Reinstall the wheel and lower the vehicle back to the ground.
