Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Power Steering Fluid

Tools Required: Fluid siphon, funnel, new power steering fluid (specific to Tesla).
Remove the power steering fluid reservoir cap.
Use a siphon to extract old fluid from the reservoir.
Inspect the old fluid for discoloration or debris.
Refill the reservoir with new power steering fluid to the recommended level.

3. Inspect and Replace Steering Components

Tools Required: Socket set, torque wrench, pry bar.
Remove the wheel and tire assembly to access steering components.
Check the condition of the tie rod ends, control arms, and bushings.
If any components are worn or damaged, replace them.
Ensure that all fasteners are torqued to manufacturer specifications upon reassembly.

4. Inspect Wheel Bearings

Tools Required: Bearing puller, grease, torque wrench.
Remove the hub assembly to access the wheel bearings.
Inspect the bearings for play or damage.
If they are worn, replace them with new bearings.
Apply high-temperature grease as per specifications before reassembling.

5. Alignment Adjustment

Tools Required: Alignment machine or alignment tools.
After reassembling the components, perform a wheel alignment.
Adjust the alignment to manufacturer specifications to ensure proper handling and tire wear.
