Problem Statement

The BMW 3 Series G20/G21 (2019-2024) is making a clicking noise when turning, which may indicate an issue with the vehicle's suspension or drivetrain components.

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical components.
•Allow the vehicle to cool before working on components near the exhaust.

Symptoms

•Clicking noise during turns, especially when steering sharply
•Increased vibration felt through the steering wheel
•Noise may vary based on the speed of the turn
•Potential loss of steering response or feel
•Visible wear or damage to suspension components during inspection

Diagnostic Steps

1
Inspect the front suspension components for wear or damage, including control arms and bushings.
2
Check the CV joints for signs of grease leakage or damage.
3
Test drive the vehicle to replicate the noise and note specific conditions (left turn, right turn, speed).
4
Examine wheel bearings for play or roughness by spinning the wheel and checking for resistance.
5
Perform a visual inspection of the steering rack and its connections for any looseness 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.

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Lift the front of the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace CV Joints

Remove the Wheel
- Use a lug wrench to loosen and remove the lug nuts.
- Take off the wheel to access the CV joint.
Inspect CV Joints
- Check for torn CV boot; if damaged, replace both the boot and the joint.
- If noise persists, proceed to replace the CV joint.
Remove the CV Joint
- Disconnect the axle bolt using a socket and ratchet.
- Pull out the CV joint from the transmission or differential.
Install New CV Joint
- Align the new CV joint with the axle and push it into place.
- Reinstall the axle bolt and torque it to the manufacturer’s specifications (typically around 25-30 Nm).

3. Inspect and Replace Suspension Components

Inspect Control Arms and Bushings
- Look for visible cracks or excessive play in the control arms and bushings.
Replace Worn Components
- If wear is evident, unbolt the control arm using a socket and ratchet.
- Install new control arms or bushings and tighten to specified torque (usually around 60-80 Nm).

4. Final Assembly

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 100-120 Nm).
