Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery.
Allow the engine to cool before starting work.

2. Inspect and Replace CV Joints

Inspect CV Joints:
- Raise the front of the vehicle using a jack and secure it with jack stands.
- Remove the front wheels to access the CV joints.
- Check for torn CV boots or excessive play in the joints.
Replace Damaged CV Joints:
- If a CV joint is damaged:
  1. Remove the axle nut using a socket wrench.
  2. Disconnect the lower control arm from the knuckle, if necessary.
  3. Slide the axle out of the transmission and remove it from the vehicle.
  4. Install the new CV joint by reversing the removal process, ensuring to torque the axle nut to the manufacturer's specifications (typically around 200 Nm for BMW).

3. Inspect and Replace Suspension Components

Inspect Control Arms and Bushings:
- Use a pry bar to check for play in the control arms and bushings.
Replace Worn Components:
- If wear is found, remove the control arm bolts and detach the control arm from the vehicle.
- Install new control arms and bushings, ensuring to torque bolts to specifications (typically around 90 Nm).

4. Check Steering Components

Inspect Steering Rack:
- Examine the steering rack for leaks or damage.
Replace if Necessary:
- If the steering rack is found to be faulty, it must be removed and replaced, ensuring all steering components are reconnected properly.
