Problem Statement

Learn how to diagnose and fix knocking noise during acceleration in Renault Clio V (2019-Present). Step-by-step guide with diagnostic procedures and repair instructions.

Affected Component

Suspension

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a level surface and securely supported before working underneath.

Symptoms

•Knocking noise during acceleration
•Noise may vary with speed or engine load
•Vibration felt through the steering wheel or floor
•Possible loss of power during acceleration
•Check engine light may illuminate (if related to drivetrain components)

Diagnostic Steps

1
Check for any visible damage or loose components in the suspension and drivetrain.
2
Use an OBD-II scanner to check for any diagnostic trouble codes that may indicate related issues.
3
Drive the vehicle under different conditions (acceleration, deceleration, cornering) to replicate the noise and assess its nature.
4
Examine engine and transmission mounts for wear or damage that could cause engine movement.
5
Check for wear or damage in the constant velocity (CV) joints and axles, as these can create knocking noises if faulty.
6
Inspect struts, shocks, and bushings for any signs of wear or damage.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, OBD-II scanner, pry bar, and flashlight.
Safety Warnings: Ensure the vehicle is on a level surface and securely supported before working underneath.

2. Inspect and Replace Engine Mounts (if needed)

Jack Up the Vehicle: Raise the front of the vehicle using a jack and secure it with jack stands.
Remove Engine Cover: If applicable, remove the engine cover for better access.
Inspect Mounts: Check engine and transmission mounts for visible cracks or damage.
Remove Bolts: Use a socket set to remove the bolts securing the damaged engine mount.
Install New Mount: Position the new mount and secure it with the bolts, torquing to manufacturer specifications (typically around 40-50 Nm).
Reinstall Engine Cover: Replace any covers removed during the process.

3. Replace CV Joints (if needed)

Remove Wheel: Use a jack to lift the vehicle and remove the wheel on the side where noise is present.
Remove Axle Nut: Remove the axle nut using a socket.
Disconnect Lower Control Arm: Detach any components connecting the lower control arm to gain access to the CV joint.
Remove CV Joint: Slide the axle out of the hub and remove the CV joint from the transmission.
Install New CV Joint: Insert the new CV joint into the transmission and reattach the axle to the hub, securing it with the axle nut (torque to 200 Nm).
Reassemble Suspension: Reconnect the lower control arm and reinstall the wheel.
