The Tesla Model S is a marvel of engineering, but like any vehicle, it can develop mechanical issues over time. One common problem that owners report is unusual noises coming from the suspension. These sounds can range from clunks to squeaks or rattles, often becoming more noticeable over uneven terrain. If you’re experiencing suspension noise in your Tesla Model S, this guide will walk you through identifying the cause and how to fix it.
Common Causes of Suspension Noise
Suspension noises in the Tesla Model S can stem from several issues:
- Worn Ball Joints: Loose or damaged ball joints can create clunking or creaking sounds.
- Damaged Control Arms: Cracked or failing bushings in the control arms may cause noise.
- Faulty Shock Absorbers: Leaking or worn shocks can lead to rattles or squeaks.
- Loose Sway Bar Links: These can cause knocking sounds during turns or over bumps.
- Dry Rubber Bushings: Lack of lubrication can lead to squeaking or creaking noises.
Understanding the root cause is key to addressing the problem effectively.
Diagnosing Suspension Noise in the Tesla Model S
1. Listen for the Type of Noise
- Clunking: Often caused by ball joints, control arms, or sway bar links.
- Squeaking or creaking: Typically linked to dry bushings or worn control arm joints.
- Rattling: May indicate loose bolts or shock absorber issues.
2. Inspect the Suspension Components
- Visual Check: Use a flashlight to examine the ball joints, bushings, and shocks for visible damage or wear.
- Manual Test: Push down on each corner of the car to see if the suspension rebounds smoothly.
3. Check for Loose or Damaged Parts
- Lift the car with a jack and inspect for any loose sway bar links, control arms, or bolts.
- Spin the wheels and check for play in the suspension components.
Fixing Suspension Noise in the Tesla Model S
1. Tighten Loose Components
- Use a torque wrench to ensure all suspension bolts are tightened to Tesla’s specifications.
- Pay special attention to sway bar links and control arm bolts.
2. Replace Worn Ball Joints or Control Arms
- If the ball joints or control arm bushings show significant wear or damage, they should be replaced.
- Tesla offers OEM parts, or you can explore third-party options for cost savings.
3. Lubricate Bushings and Moving Parts
- Apply a silicone-based lubricant to rubber bushings to eliminate squeaks.
- Avoid petroleum-based lubricants, which can degrade rubber over time.
4. Inspect and Replace Shock Absorbers
- If shocks are leaking fluid or fail the bounce test, they need to be replaced.
- Consider replacing shocks in pairs to maintain balanced handling.
5. Realign the Suspension System
- After any major repairs, have a professional realign your suspension to ensure optimal performance and even tire wear.
When to Contact Tesla Service

Preventing Future Suspension Noise
1. Regular Maintenance
- Schedule periodic inspections to catch wear and tear early.
- Check suspension components every 10,000–15,000 miles.
2. Drive Carefully Over Rough Terrain
- Avoid potholes and rough roads when possible to reduce stress on suspension components.
3. Keep Components Lubricated
- Apply lubrication during routine maintenance to prevent squeaks and prolong bushing life.
