Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Raise the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on where the noise is coming from.
Secure the vehicle on jack stands for safety.

3. Inspect and Replace Components

Shock Absorbers/Struts:
- Remove the wheel to access the strut assembly.
- Use a socket set to unbolt the strut from its mount and lower control arm.
- Remove the strut assembly and inspect for leaks or damage.
- Replace with a new strut if necessary, following the manufacturer’s specifications for torque values during reinstallation.
Sway Bar Links:
- Locate the sway bar links attached to the strut and sway bar.
- Remove the bolts using a wrench and replace the sway bar links if worn.
Bushings:
- Inspect bushings in control arms and sway bars for wear.
- Remove any damaged bushings and replace with new ones, ensuring proper orientation.
Coil Springs:
- If the coil springs show signs of damage, remove them by unbolting the strut assembly and using a spring compressor to safely detach the springs.
- Replace with new springs as necessary.

4. Reassemble and Lower Vehicle

Reassemble all components in the reverse order of disassembly.
Double-check torque specifications for all bolts.
Lower the vehicle back to the ground and reconnect the negative battery terminal.
