Problem Statement

Learn how to diagnose and fix knocking noise in Honda Civic 10th Generation (2016-2021). 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

•Always disconnect the battery before working on electrical or suspension systems.
•Ensure the vehicle is securely lifted and supported before working underneath it.

Symptoms

•Knocking noise during acceleration or deceleration
•Noise becomes louder over bumps or rough terrain
•Vibration felt through the steering wheel or floor
•Potential loss of handling or stability
•Unusual tire wear patterns

Diagnostic Steps

1
Inspect the suspension components for signs of wear or damage (e.g., struts, control arms, bushings).
2
Check engine mounts for any visible cracks or degradation.
3
Perform a visual inspection of the drivetrain components, including axles and CV joints.
4
Test drive the vehicle while listening for noise changes during different driving conditions (turning, braking).
5
Use a stethoscope or mechanic's stethoscope to localize the noise source if needed.
6
Inspect the tires for uneven wear and ensure proper inflation.

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

Tools & Equipment Required

•Jack and jack stands
•Lug wrench
•Socket set
•Torque wrench
•Mechanic's stethoscope (optional)

Parts Required

•Strut assembly (if needed)
•Control arm bushings (if needed)
•Engine mounts (if needed)
•CV axle (if needed)

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely lift it using a jack and jack stands.
Disconnect the battery to ensure safety while working on suspension components.

2. Inspect and Replace Suspension Components

Remove Wheel
- Use a lug wrench to remove the wheel corresponding to the side of the vehicle making noise.
Inspect Shock Absorbers/Struts
- Check for leaks or damage. If defective, proceed to remove:
  - Use a socket set to unbolt the strut from the knuckle and top mount.
  - Replace with new strut assembly, ensuring proper torque specification (typically 15-20 ft-lbs for top bolts, 50-60 ft-lbs for knuckle bolts).
Examine Control Arms and Bushings
- Inspect for wear or damage. If bushings are cracked or worn, replace them:
  - Remove bolts securing the control arm using a socket set.
  - Press out the old bushings and install new ones.
  - Reinstall the control arm, ensuring it is torqued to manufacturer specifications.

3. Inspect and Replace Engine Mounts

Locate Engine Mounts
- Identify the engine mounts (usually located on the front, rear, and sides of the engine).
Remove Engine Mounts
- Use a socket set to unbolt the engine mounts. Support the engine with a jack if necessary.
- Replace mounts with new ones, ensuring bolts are torqued to specifications (typically around 40-60 ft-lbs).

4. Inspect and Replace Drivetrain Components

Check CV Joints and Axles
- Inspect for torn boots or excessive play.
- If damaged, remove the axle by loosening the axle nut with a socket, then pull the axle from the hub and transmission.
- Install the new axle and secure it with the axle nut (torque to approximately 100 ft-lbs).
