how to fix a CV joint noise in my BMW 3 Series E90/E91 (2005-2012)

Solution

1. Preparation

• Tools Required: Jack, jack stands, wheel chocks, lug wrench, socket set, torque wrench, pry bar, CV joint grease, new CV joint or boot kit (if necessary).
• Safely lift the vehicle and support it on jack stands. Ensure the vehicle is in gear or in park (for automatic transmission) and the parking brake is applied.

2. Remove Wheel and Axle

1. Loosen the lug nuts using a lug wrench while the vehicle is still on the ground.
2. Lift the vehicle with a jack and securely place it on jack stands.
3. Remove the wheel to access the CV joint and axle.
4. Remove any clips or bolts securing the axle to the hub assembly.

3. Inspect and Replace CV Joint

1. Use a pry bar to gently separate the CV joint from the transmission or differential.
2. If the boot is torn, remove the old boot and clean the CV joint thoroughly.
3. If the CV joint is damaged or excessively worn, replace it with a new joint. Follow the manufacturer's guidelines for any specific procedures.
4. Apply fresh CV joint grease to the new joint, ensuring it's adequately lubricated before sealing.
5. Install a new boot over the joint, securing it with clamps.

4. Reassemble Components

1. Reattach the CV joint to the transmission or differential, ensuring it's seated properly.
2. Reinstall the axle into the hub assembly, securing it with the appropriate bolts or clips.
3. Reattach the wheel and hand-tighten the lug nuts initially.

5. Lower Vehicle and Finalize

1. Lower the vehicle back to the ground using the jack.
2. Torque the lug nuts to the manufacturer’s specified torque value.
3. Clean up any tools and materials used during the process.
