Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Tie Rod Ends

Sub-steps:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Remove the wheel on the side where the clicking is heard using a socket set.
3. Locate the tie rod end and inspect for any damage or play.
4. If worn, use a tie rod end puller to remove the old tie rod end.
5. Install the new tie rod end and tighten to manufacturer's specifications (typically around 40-50 Nm).
6. Reinstall the wheel.

3. Inspect and Replace Ball Joints

Sub-steps:
1. If the ball joints are suspected, remove any necessary components for access (like the wheel hub).
2. Use a ball joint separator tool to remove the ball joint from the control arm.
3. Install the new ball joint and secure it with the appropriate torque (usually around 60-70 Nm).
4. Reassemble any removed components.

4. Check and Refill Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir.
2. Check the fluid level; if low, top up with the recommended type of power steering fluid (usually ATF or specific fluid for BMW).
3. Start the engine and turn the steering wheel left and right to circulate fluid.
