Fix Your Tesla Suspension Noise.
We Come to You.

What you hear: A heavy, dull thud or clunk when driving over speed bumps, potholes, or uneven pavement.

What is likely causing it: This is one of the most common Tesla suspension complaints. It usually points to worn front lower control arm bushings or a failing front compression arm (also called a compliance link). The rubber bushings absorb the fore-and-aft forces of braking and acceleration. When the rubber tears or separates from the metal sleeve, the arm can knock against the subframe. On the Model 3 and Model Y, the front lower lateral link bushing is a frequent offender. On the Model S and Model X, worn lower control arm ball joints and degraded bushings are common at higher mileage.

The ball joints on these control arms wear out over time, causing looseness and clunking noises.

What you hear: A rhythmic squeaking or creaking sound when turning the steering wheel at low speeds, such as in a parking lot or when pulling out of a driveway.

What is likely causing it: This is the signature symptom of a failing front upper control arm ball joint on the Model 3 and Model Y. Water works its way past the ball joint seal over time, displacing the grease and causing corrosion inside the joint. Once the grease is gone, the metal-on-metal contact creates that unmistakable squeak. This is a known design vulnerability on these models, and the ball joint is not serviceable on its own. The entire upper control arm must be replaced.

The front upper control arm connects the top of your wheel to the car frame. When water gets inside the ball joint, it dries out the grease and causes a loud squeak.

What you hear: A rapid, light rattling sound from the front of the car, especially noticeable at lower speeds over rough pavement or expansion joints.

What is likely causing it: Sway bar end links are the most common cause of this symptom. As the ball joints inside the end links wear out, they develop play. Every small movement of the suspension causes them to rattle. This is one of the least expensive repairs on the list and one of the most satisfying to fix, because the rattle disappears immediately. Loose or worn sway bar bushings can also contribute to this noise.

Sway bar end links connect your suspension to a bar that keeps the car flat when going around corners. When they get loose, they rattle rapidly over small bumps.

What you hear: A vibration or shimmy felt through the steering wheel or the seat at speeds above 55 mph, sometimes accompanied by a low humming sound.

What is likely causing it: While tire imbalance is always the first thing to rule out, persistent highway vibrations can also stem from worn tie rod ends or failing suspension bushings that can no longer maintain precise wheel alignment under load. A worn tie rod end introduces play in the steering linkage, which can cause the front wheels to oscillate slightly at speed. This symptom is worth diagnosing promptly, as it can accelerate tire wear.

What you hear: A distinct knock or thump, often felt as much as heard, when the suspension compresses and rebounds over a speed bump.

What is likely causing it: A sharp, single knock during full suspension travel typically indicates a failing front compression arm or compliance link. These components control the fore-and-aft movement of the front wheel. When the bushing fails, the arm has excess play and can knock against the subframe during hard compression. On the Model S and Model X, worn strut top mounts can produce a similar single-knock sound.

What you hear and see: The car sits noticeably lower on one corner, or the entire front or rear drops overnight. The suspension may pump itself back up when you start the car, or it may not recover at all. You may also notice a ride height warning on the touchscreen.

What is likely causing it: The air suspension system on the Model S and Model X uses pressurized air struts instead of conventional coil springs. These struts can develop leaks at the air bag, the air line connections, or the strut body itself. Early Model S vehicles (pre-2016) are particularly prone to air suspension issues due to the age of the components. A leaking air strut will cause the car to sag on the affected corner. In some cases, the compressor runs constantly trying to maintain pressure, which accelerates compressor wear.

What you hear: A slow, low-pitched creak from the rear of the vehicle when you sit down in the seat or step out, as the suspension loads and unloads.

What is likely causing it: This is the classic symptom of a failing rear traction arm bushing. The factory bushing, which is pressed into the stamped steel arm, can separate from the metal over time. When the bushing separates, the arm has increased play and creaks as the suspension moves. This issue is particularly common on 2017 through 2020 Model Y vehicles. The 2021 and later Model Y uses a revised arm design that largely addresses this problem.
