2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under a vehicle.
•Allow the vehicle to cool down before working on suspension components if it has been recently driven.

Symptoms

•Squeaking noise when driving over bumps or uneven surfaces
•Decreased ride comfort or harshness in the suspension
•Increased body roll during cornering
•Visual inspection may show worn or damaged bushings
•Possible uneven tire wear

Diagnostic Steps

1
Inspect the suspension components, including control arms, bushings, and struts, for visible wear or damage.
2
Check for loose or missing hardware in the suspension system.
3
Perform a bounce test by pushing down on the car's corners to assess the shock absorbers' function.
4
Use a stethoscope or similar tool to isolate the source of the squeak while having an assistant bounce the vehicle.
5
Inspect the sway bar links and bushings for play and wear.
6
Verify that the tires are properly inflated and in good condition.

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands for safety.
Ensure the vehicle is stable before working underneath.

3. Inspect and Replace Components

Control Arm Bushings:
1. Remove the wheel by loosening the lug nuts and taking off the wheel.
2. Locate the control arm and inspect the bushings for cracks or wear.
3. If damaged, remove the control arm by loosening the bolts using a socket set.
4. Replace the bushings with new ones, ensuring proper alignment.
5. Reinstall the control arm and tighten the bolts to the manufacturer's specified torque (usually around 50-60 ft-lbs for control arm bolts).
Sway Bar Links:
1. Inspect the sway bar links for play or wear.
2. If they are worn, remove them by loosening the bolts at both ends with a socket set.
3. Replace with new sway bar links and torque bolts to specification.

4. Lubrication

Apply silicone-based grease to all rubber bushings and joints to reduce friction and eliminate squeaks.
Wipe away excess grease to prevent dirt accumulation.

5. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then torque the lug nuts to the manufacturer's specification (typically 80-100 ft-lbs).
