Estimated Time

3-5 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the 12V battery before working on electrical systems.
•Always use jack stands when working under the vehicle.

Symptoms

•Loud noise that increases with acceleration
•Vibration felt through the vehicle
•Unusual sounds such as grinding or clunking
•Decreased acceleration performance
•Possible warning lights illuminated on the dashboard

Diagnostic Steps

1
Inspect the vehicle visually for any noticeable damage or loose components.
2
Perform a scan for error codes using a Tesla diagnostic tool to identify potential electronic faults.
3
Check the wheel bearings for wear or damage, as this can produce noise during acceleration.
4
Inspect the drive unit and associated components (such as the driveshaft) for signs of wear or damage.
5
Test the suspension components for wear, including bushings and shock absorbers.
6
Listen for noise while stationary by revving the motor to isolate the location of the noise.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the 12V battery for safety.

2. Inspect and Replace Wheel Bearings

Tools Required: Socket set, torque wrench, wheel chock.
Remove the wheel using the socket set.
Inspect the wheel bearings for any signs of damage or excessive play.
If damaged, replace the wheel bearings:
- Remove the retaining clips and bearing caps.
- Use a bearing puller to extract the old bearings.
- Install new bearings, ensuring they are properly seated.
- Reassemble the wheel and torque to manufacturer specifications.

3. Check and Repair Drive Unit

Tools Required: Ratchet set, torque wrench, jack and jack stands.
Lift the vehicle using a jack and secure it on jack stands.
Inspect the drive unit for any signs of leakage or damage.
If issues are found, replace the drive unit:
- Disconnect electrical connectors and fluid lines.
- Unbolt the drive unit from the chassis.
- Install the new drive unit, securing all bolts to the specified torque.
- Reconnect electrical connectors and fluid lines.

4. Inspect and Replace Suspension Components

Tools Required: Wrench set, torque wrench, alignment tool.
Check all suspension components for wear, especially bushings and shock absorbers.
Replace any worn components:
- Remove the affected suspension part by loosening bolts.
- Replace with new parts and torque bolts to manufacturer specifications.
- Perform a wheel alignment to ensure proper handling.
