Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the battery to prevent electrical issues while working on the suspension.

2. Inspect Suspension Components

Tools Required: Socket set, jack stands, and pry bar.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the suspension components.
Visually inspect the control arms, tie rods, and sway bar links for signs of damage or wear.

3. Replace Worn Bushings

Tools Required: Bushing removal tool, lubricant, and socket set.
If any bushings are worn or cracked, proceed to remove the affected component.
Use the bushing removal tool to extract the old bushing.
Lubricate the new bushing and install it, ensuring it is properly seated.
Reattach the component and tighten fasteners to the manufacturer’s torque specifications.

4. Check and Replace Struts/Shocks (if necessary)

Tools Required: Strut spring compressor, socket set, and torque wrench.
If struts or shocks are leaking or damaged, remove them by loosening the mounting bolts.
Use a strut spring compressor to safely remove the coil spring from the strut assembly.
Replace any faulty struts or shocks with new ones, reassembling in reverse order.
Ensure all fasteners are torqued to the manufacturer's specifications.

5. Reassemble and Test

Reattach the wheel and lower the vehicle.
Reconnect the battery.
Test drive the vehicle over various surfaces to confirm the squeaking noise has been resolved.
