Suspension

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always secure the vehicle properly when lifted to prevent accidents.
•Disconnect the 12V battery before working on electrical components.

Symptoms

•Vehicle shakes or vibrates during acceleration
•Steering wheel vibration
•Unusual noises from the drivetrain
•Decreased acceleration performance
•Loss of traction or stability

Diagnostic Steps

1
Inspect tire condition and pressure for uneven wear or low inflation.
2
Check for loose or damaged suspension components, including control arms and bushings.
3
Examine the driveshaft and axles for any signs of damage or wear.
4
Scan the vehicle's onboard diagnostics using the Tesla service tool for any error codes.
5
Perform a visual inspection of the brake components for any binding or damage.
6
Test drive the vehicle to replicate the shaking and note the speed and conditions under which it occurs.

Solution

Solution

1. Tire Inspection

Sub-steps:
1. Use a tire pressure gauge to check all tire pressures; inflate to the recommended levels.
2. Inspect tires for uneven wear patterns or visible damage such as bulges or cuts.
3. If necessary, rotate or replace tires according to the wear condition.

2. Suspension Component Check

Sub-steps:
1. Lift the vehicle using a jack and secure with jack stands.
2. Visually inspect control arms, bushings, and shock absorbers for wear or damage.
3. Replace any worn or damaged components using the appropriate tools.

3. Drivetrain Examination

Sub-steps:
1. Inspect the driveshaft and axles for signs of wear or damage.
2. Check for any play in the joints by manually moving them.
3. Replace any damaged driveshaft or axle assemblies.

4. Error Code Scan

Sub-steps:
1. Connect the Tesla service tool to the OBD-II port.
2. Retrieve and document any error codes present.
3. Research the codes for specific repairs or maintenance actions required.

5. Brake Component Inspection

Sub-steps:
1. Inspect brake rotors and pads for uneven wear or binding.
2. Check for any debris or rust that might be causing brake drag.
3. Replace any damaged or worn brake components as necessary.
