⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under a vehicle.
•Ensure the vehicle is on a flat surface before lifting.
•Allow components to cool before handling if the vehicle has been driven.

Symptoms

•Clunking noise when driving over bumps
•Possible rattling sound when driving on uneven surfaces
•Decreased ride comfort or stability
•Visual inspection may reveal worn or damaged suspension components
•Excessive tire wear or alignment issues

Diagnostic Steps

1
Inspect the suspension components visually for any visible signs of damage or wear, including struts, shocks, and control arms.
2
Perform a bounce test on each corner of the vehicle to check for excessive play in the suspension.
3
Check the mounting bolts and bushings for the struts and shock absorbers to ensure they are tight and not damaged.
4
Examine the undercarriage for loose or damaged components that could be causing the noise.
5
Test drive the vehicle over bumps while a technician listens from outside to pinpoint the source of the noise.

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench.
Park the vehicle on a flat surface, engage the parking brake, and ensure the engine is off.

2. Lift the Vehicle

Use the jack to lift the vehicle at the designated lift points.
Secure the vehicle with jack stands to ensure safety.

3. Inspect and Replace Suspension Components

Sub-steps:
1. Remove the wheel using the lug wrench.
2. Inspect the struts and shocks for leaks or physical damage.
3. Check the control arm bushings and ball joints for wear; replace them if cracked or loose.
4. If struts or shocks are worn, remove and replace them:
  - Unbolt the top mount from the strut tower inside the engine bay.
  - Remove the bottom bolts securing the strut to the knuckle.
  - Replace with new struts/shocks and torque bolts to manufacturer specifications.
5. Reattach any loose components, ensuring all bolts are tightened to the specified torque.

4. Reassemble and Lower the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Torque the lug nuts to the manufacturer's specified torque.
