•Reduced handling and stability

Diagnostic Steps

1
Inspect tire pressure for all four tires to ensure they are at manufacturer-recommended levels.
2
Check for visible damage or defects on the tires, including bulges, cracks, or foreign objects.
3
Perform a visual inspection of the suspension components for signs of wear or damage.
4
Use a tread depth gauge to measure tire tread depth across different points on each tire.
5
Test wheel alignment using a laser alignment tool to determine if the angles are within specifications.
6
Examine the vehicle's steering system for any play or looseness that may contribute to uneven wear.

Solution

1. Preparation

Gather tools and parts required for the task.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Safety glasses and gloves should be worn.

2. Tire Rotation

Sub-steps:
1. Loosen lug nuts on all four wheels using a socket set.
2. Raise the vehicle using a hydraulic jack and secure it with jack stands.
3. Remove the wheels and inspect the tire wear patterns.
4. Rotate tires according to the manufacturer’s recommendations (e.g., front to rear, side to side).
5. Reinstall the wheels and torque the lug nuts to the manufacturer's specifications (typically 100-120 ft-lbs for Model 3).

3. Alignment Adjustment

Sub-steps:
1. Take the vehicle to a professional alignment shop equipped with a computerized alignment system.
2. Adjust the alignment settings for camber, toe, and caster according to Tesla specifications.
3. Confirm that all adjustments are within the manufacturer's specified ranges.

4. Suspension Repair (if needed)

Sub-steps:
1. If any suspension components are found to be damaged during inspection, replace them using the appropriate parts (e.g., control arms, bushings).
2. Follow the manufacturer’s specifications for torque settings during reinstallation of new components.
3. Recheck alignment after any suspension repairs.
