Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check fluid level; if low, drain any old fluid and replace with recommended Tesla power steering fluid.
Recheck fluid level and replace the cap securely.

3. Inspect and Replace Steering Components

Lift the front of the vehicle using a jack and secure with jack stands.
Remove the front wheels using a socket set.
Check tie rods and ball joints for play; replace any worn components.
If components are damaged, remove them using a wrench and install new parts, ensuring they are torqued to manufacturer specifications.

4. Inspect and Replace Wheel Bearings

Remove the brake caliper and rotor from the affected wheel.
Inspect the wheel bearing by spinning it; if grinding is felt, replace it.
To replace, remove the wheel hub assembly and install a new bearing, applying proper torque specifications during reassembly.

5. Reassemble and Recheck

Reinstall the wheels and lower the vehicle.
Reconnect the negative battery terminal.
Start the vehicle and check for any abnormal noises or issues during a brief test drive.
