Affected Component

Suspension

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use proper lifting equipment and safety stands when working underneath the vehicle.
•Allow the vehicle to cool before inspecting any components that may have been in use.

Symptoms

•Noticeable wear patterns on tire tread (e.g., cupping, scalloping)
•Increased road noise while driving
•Vehicle pulls to one side while driving
•Reduced traction or handling performance
•Frequent need for tire rotation or replacement

Diagnostic Steps

1
Inspect tire pressure on all four tires; ensure they are inflated to the manufacturer's recommended levels.
2
Check wheel alignment using a laser alignment tool to determine if any wheels are misaligned.
3
Examine suspension components (shocks, struts, control arms) for wear or damage.
4
Look for any signs of uneven wear on brake pads and rotors that could affect tire performance.
5
Review Tesla’s maintenance history to check for any previous alignments, rotations, or tire-related services.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

•Tire pressure gauge
•Laser alignment tool
•Torque wrench
•Socket set
•Wheel chocks

Parts Required

•Replacement suspension components (if necessary)
•New tires (if current tires are excessively worn)

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Safety: Engage the parking brake and use wheel chocks.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the PSI of each tire.
Inflate or deflate tires as needed to meet the manufacturer's specifications (typically found on the driver's door jamb).

3. Wheel Alignment

Using a laser alignment tool, measure the alignment of all four wheels.
Adjust camber, caster, and toe settings according to Tesla’s specifications (refer to the service manual for exact angles).

4. Suspension Inspection and Repair

Visually inspect suspension components for any signs of damage or wear.
Replace any worn or damaged components (e.g., shocks, struts, control arms) as necessary.
Re-test wheel alignment post-repair to ensure proper settings.

5. Tire Rotation

If uneven wear patterns are present, rotate the tires according to the recommended pattern (typically front-to-back and side-to-side).
Ensure the lug nuts are torqued to the manufacturer's specifications (usually around 100-110 ft-lbs).
