Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery for safety.

2. Tire Pressure Adjustment

Sub-steps:
1. Use a tire pressure gauge to check the pressure of each tire.
2. Inflate or deflate tires to match the manufacturer’s specifications, usually found on the driver’s side door jamb.
3. Recheck pressures after adjustments.

3. Tire Inspection and Replacement

Sub-steps:
1. Visually inspect each tire for damage or wear.
2. If any tires are damaged or excessively worn, remove them using a tire iron.
3. Replace with new tires if necessary, ensuring they are properly balanced.
4. Torque lug nuts to the manufacturer’s specifications (typically around 100 ft-lbs for Tesla).

4. Wheel Alignment

Sub-steps:
1. Take the vehicle to a certified alignment shop.
2. Request a four-wheel alignment, ensuring that all settings conform to the manufacturer’s specifications.
3. Verify that the alignment is within acceptable ranges.

5. Suspension Component Inspection

Sub-steps:
1. Lift the vehicle using a hydraulic jack and secure it with jack stands.
2. Inspect all suspension components (shocks, struts, control arms) for signs of wear or damage.
3. Replace any damaged components as necessary, following manufacturer specifications for torque and installation.
