Problem Statement

Learn how to check for worn struts on your Tesla Model 3 Highland (2024-present). Step-by-step diagnostic and inspection guide for better ride quality.

Affected Component

Suspension

Estimated Time

1-2 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a flat surface.
•Engage the parking brake and put wheel chocks behind the rear tires.
•Ensure the vehicle is securely supported before working underneath.
•Always wear safety glasses and gloves when performing mechanical inspections.

Symptoms

•Excessive bouncing or swaying during turns
•Nose diving during braking
•Uneven tire wear
•Leaking fluid from the strut assembly
•A clunking noise over bumps
•Reduced overall ride comfort

Diagnostic Steps

1
Perform a visual inspection of the struts for any signs of fluid leakage.
2
Push down on each corner of the vehicle to observe the rebound; a well-functioning strut should return to its original position quickly.
3
Check for any physical damage or deformation on the strut assembly.
4
Inspect the surrounding components for wear or looseness, including mounts and bushings.
5
Conduct a test drive to evaluate handling, stability, and ride comfort under different conditions (highway, bumps, turns).
6
Measure tire wear patterns to identify any irregularities that could indicate strut issues.

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

•Floor jack
•Jack stands
•Tire pressure gauge
•Torque wrench
•Inspection mirror (optional)

Parts Required

•Replacement struts (if worn out)
•New strut mounts (if necessary)

Solution

1. Preparation

Gather tools and parts necessary for inspection.
Tools Required:
- Floor jack
- Jack stands
- Tire pressure gauge
- Torque wrench
- Inspection mirror (optional)
Safety Warnings:
- Ensure the vehicle is on a flat surface.
- Engage the parking brake and put wheel chocks behind the rear tires.

2. Lift the Vehicle

Use the floor jack to lift the front or rear of the vehicle, depending on which struts you are inspecting.
Secure the vehicle with jack stands before proceeding.

3. Inspect the Struts

Visually check each strut for:
- Signs of oil leakage
- Dents or bends in the strut body
Use an inspection mirror to check hard-to-see areas.

4. Conduct a Bounce Test

Stand at a corner of the vehicle and push down firmly on the bumper.
Release it and observe the movement; the vehicle should rebound once and settle back. If it bounces multiple times, the struts may be worn.

5. Check for Noises

While pushing down, listen for any clunking or knocking sounds, which could indicate internal failure of the struts.

6. Final Assessment

If any of the inspections indicate potential wear or damage, consider replacing the struts as needed.
