Solution

1. Preparation

Gather tools and materials: jack, jack stands, tire pressure gauge, torque wrench, socket set, diagnostic tool.
Park the vehicle on a level surface and engage the parking brake.

2. Tire Pressure Adjustment

Sub-step 1: Remove valve caps from all tires.
Sub-step 2: Use the tire pressure gauge to measure the pressure in each tire.
Sub-step 3: Inflate or deflate to the recommended pressure found in the owner's manual or on the driver's door jamb.
Sub-step 4: Replace valve caps securely.

3. Tire Inspection and Replacement

Sub-step 1: Inspect all tires for signs of damage or uneven wear.
Sub-step 2: If any tires are excessively worn or damaged, replace them with new tires.
Sub-step 3: Ensure new tires are balanced properly before installation.

4. Suspension Component Inspection and Replacement

Sub-step 1: Lift the vehicle using a jack and secure it with jack stands.
Sub-step 2: Check the condition of shock absorbers and struts for leaks or physical damage.
Sub-step 3: If damaged, remove old shocks/struts using a socket set, following manufacturer torque specifications for reinstallation.
Sub-step 4: Install new shocks/struts and torque fasteners to the specified values.

5. Wheel Alignment

Sub-step 1: Take the vehicle to a professional for a four-wheel alignment to ensure proper suspension geometry.
Sub-step 2: Confirm alignment settings match Tesla specifications.
