my Volvo XC90 makes a clunking noise when turning, what could it be?

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a flat surface and engage the parking brake.
• Disconnect the battery if working on electronic components.

2. Inspect and Replace CV Joint (if necessary)

• Tools Required: Socket set, pry bar, torque wrench, CV joint replacement kit.
• Remove the wheel by loosening the lug nuts and using a jack to lift the vehicle.
• Sub-steps:
  1. Remove the axle nut using a socket.
  2. Detach the lower control arm from the steering knuckle using a pry bar for leverage.
  3. Slide the CV joint out of the transmission or differential.
  4. Inspect the old CV joint for wear and replace it with a new joint, ensuring it's properly seated.

3. Inspect and Replace Wheel Bearings (if necessary)

• Tools Required: Bearing puller, socket set, torque wrench.
• Sub-steps:
  1. Remove the wheel and brake caliper for access to the hub.
  2. Detach the hub assembly from the suspension.
  3. Use a bearing puller to remove the old bearing and replace it with a new one.
  4. Reassemble the hub and torque all components to the specified values.

4. Check Suspension Components

• Tools Required: Wrench set, torque wrench.
• Sub-steps:
  1. Inspect the struts and shocks for leaks or damage and replace if necessary.
  2. Tighten any loose bolts or nuts on the suspension components.
  3. Perform a visual inspection of bushings and replace any that are worn or cracked.
