Important safety information - read before proceeding

•Always use jack stands when working under a vehicle.
•Wear safety glasses when working with suspension components to protect eyes from debris.

Symptoms

•Clunking noise when hitting potholes or bumps
•Deterioration in ride quality, feeling rough
•Excessive body roll during turns
•Possible uneven tire wear
•Visual inspection may reveal damaged suspension components

Diagnostic Steps

1
Inspect the suspension components visually for signs of wear or damage, such as the struts, shocks, and control arms.
2
Check the bushings for any cracks or deterioration that could contribute to noise.
3
Examine the sway bar links and mounts for looseness or damage.
4
Test the shock absorbers for proper function by pushing down on the corners of the vehicle; it should rebound smoothly.
5
Lift the vehicle and perform a wiggle test on the wheels to check for play in the suspension joints.

Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Disconnect the battery if electrical components will be accessed.

2. Remove Damaged Components

Struts/Shocks Replacement:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Remove the wheel for access.
3. Unbolt the strut/shock from the lower control arm and upper mount.
4. Carefully remove the strut/shock assembly from the vehicle.

3. Inspect and Replace Bushings

1. Remove any damaged bushings from the control arms or sway bar links.
1. Clean any residue from the mounting points.
1. Install new bushings, ensuring they are properly aligned and secured.

4. Install New Components

Installing Struts/Shocks:
1. Position the new strut/shock into the mounting location.
2. Torque bolts to the manufacturer’s specifications (typically around 60-80 ft-lbs for strut mounts, consult the manual).
3. Reattach the wheel and lower the vehicle.

5. Final Checks

1. Perform a visual inspection to ensure all components are fitted correctly.
1. Reconnect the battery if it was disconnected.
1. Conduct a test drive to check for noise and ensure proper function.
