Learn how to check for worn out shocks in your Tesla Model S (2012-2020). Step-by-step diagnostic and inspection guide for suspension issues.

Affected Component

Suspension

Estimated Time

1-2 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is securely supported when performing any work underneath.
•Always use proper lifting equipment and follow safety protocols when inspecting suspension components.

Symptoms

•Excessive bouncing after hitting bumps
•Poor handling and increased body roll during turns
•Uneven tire wear
•Noticeable noise from the suspension when driving over bumps
•Vehicle sagging or sitting lower than normal

Diagnostic Steps

1
Visually inspect the shocks for any signs of fluid leakage or physical damage.
2
Perform a bounce test by pushing down on each corner of the vehicle and observing how quickly it returns to its original position.
3
Check the mounting hardware for tightness and any signs of wear or corrosion.
4
Inspect the tires for uneven wear patterns that may indicate suspension issues.
5
Listen for unusual noises when driving over bumps or during turns, which could suggest shock deterioration.

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

•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

•Socket set
•Tread depth gauge
•Torque wrench

Parts Required

•Replacement shocks (if worn out)
•New mounting hardware (if necessary)

Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Gather necessary tools and equipment.

2. Visual Inspection

Sub-steps:
- Examine each shock absorber for signs of oil leakage. A wet or oily appearance indicates a failed seal.
- Check for dents, cracks, or rust on the shock body and mounts.

3. Perform Bounce Test

Sub-steps:
- Stand at the front or rear corner of the vehicle and push down firmly.
- Release the pressure and observe how many times the vehicle bounces before settling. Ideally, it should bounce once and settle without excessive motion.

4. Check Mounting Hardware

Sub-steps:
- Using a socket set, check the tightness of the bolts securing the shocks. Ensure they are torqued to the manufacturer's specifications.
- Look for any signs of wear or rust on the bolts and mounting points.

5. Inspect Tire Wear

Sub-steps:
- Examine the tread pattern on each tire. Worn shocks may cause uneven wear, such as cupping or excessive wear on one side.
- Use a tread depth gauge to measure if the wear is uneven across the tire surface.
