Solution

1. Preparation

Gather tools such as a jack, jack stands, wrench set, and possibly a torque wrench.
Ensure the vehicle is on a flat surface and the engine is off.
Safety Warning: Disconnect the battery before working on electrical components.

2. Inspect and Replace Bushings

Sub-steps:
1. Use a jack to lift the vehicle and secure it with jack stands.
2. Remove the wheel to access the suspension components.
3. Inspect the control arm bushings for cracks or wear.
4. If damaged, remove the old bushings using a bushing removal tool.
5. Install new bushings, ensuring they are properly seated.
6. Reassemble the control arm and wheel, torqueing bolts to factory specifications.

3. Check and Replace Struts/Shocks

Sub-steps:
1. Inspect the struts/shocks for oil leakage and physical damage.
2. If leaking or damaged, remove the strut/shock assembly from the vehicle.
3. Compress the coil spring using a spring compressor if the struts are coil-over types.
4. Replace the strut/shock with a new one, ensuring it matches OEM specifications.
5. Reassemble the suspension and torque all bolts to the manufacturer's specifications.

4. Lubricate Components

Sub-steps:
1. Identify any grease fittings on the suspension components.
2. Use a grease gun to apply appropriate grease to the fittings.
3. Ensure all moving parts are well lubricated to reduce friction and noise.
