⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under the vehicle.
•Allow the vehicle to cool before working on any components to prevent burns.

Symptoms

•Vibrations felt through the steering wheel or floor during acceleration
•Unusual noises accompanying the vibrations (e.g., humming or grinding)
•Steering wheel shaking at higher speeds
•Decreased acceleration performance

Solution

1. Tire Inspection and Maintenance

Sub-steps:
1. Inspect all tires for bulges, cuts, or uneven wear.
2. Check and adjust tire pressure according to manufacturer specifications (usually around 42 PSI for Model 3).
3. Rotate tires if uneven wear is detected.
Tools Required: Tire pressure gauge, tire rotation tools.

2. Wheel Alignment and Balancing

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Perform a four-wheel alignment to ensure all wheels are aligned to factory specifications.
3. Balance the tires using a wheel balancer machine.
Tools Required: Alignment machine, wheel balancer.

3. Suspension Inspection and Repair

Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Inspect all suspension components (struts, shocks, bushings) for wear or damage.
3. Replace any defective components as necessary.
4. Reassemble the suspension and lower the vehicle.
Tools Required: Jack, jack stands, socket set, torque wrench.

4. Drivetrain Inspection

Sub-steps:
1. Inspect the driveshaft and axles for any visible damage or excessive play.
2. Tighten any loose bolts on the driveshaft and inspect the universal joints.
3. Replace any damaged components as necessary.
Tools Required: Socket set, torque wrench.
