ToggleTesla Model 3 Ball Joint & Upper Control Arm Repair
Creaking, squeaking, clunking, steering looseness, or uneven tire wear? A well-documented design flaw lets water enter the front upper control arm ball joint — and Ontario road salt makes it worse.

Hearing a creak, squeak, or clunk from the front end of your Tesla Model 3? This is one of the most common issues we see from GTA Model 3 owners — and Ontario road salt makes it significantly worse than in drier climates. Radman is EV certified and has diagnosed Model 3 suspension issues for Toronto and Etobicoke drivers since the Model 3 launched.
What’s Actually Failing on Your Model 3
The front upper control arm connects the steering knuckle to the chassis, letting the wheel move over bumps while maintaining steering geometry. At its end is a ball joint. Tesla’s original design used a hybrid steel/fibre-reinforced-plastic construction with a plastic cap over the joint — and the cap’s lip sits at the lowest point of the arm. Water drains onto the arm, seeps under the cap, washes out the grease, and causes corrosion.
Critically: the ball joint is not serviceable separately — Tesla supplies the arm as a complete assembly, so when the joint fails, the entire front upper control arm must be replaced.
Tesla Service Bulletins & Recalls You Need to Know
Tesla has revised the upper control arm multiple times. When replacing yours, we install the latest available revision — not old-stock parts carrying the same flaw.
Symptoms: What You’re Hearing & What It Means
The Model 3’s near-silent drivetrain makes suspension noises far more noticeable than in gas vehicles.
Creaking / Squeaking
Most common first symptom. Loudest at low speeds, parking lots, slow turns, or steering lock to lock.
Clunking / Knocking
The squeak has progressed to a clunk over bumps or braking — indicates significant ball joint play.
Steering Vagueness
Steering feels less precise, or the car wanders slightly as wheel geometry shifts unpredictably.
Uneven Tire Wear
Unusual inner or outer wear. No alignment will hold until the worn arm is replaced.
Pulling / Instability
Advanced failure. Stop driving and book service immediately if the vehicle feels unstable.
How it progresses if ignored: water ingress washes away grease → corrosion causes creaking → wear creates a measurable clunk and uneven tire wear → joint separation can cause immediate loss of steering control on that wheel.
The Right Repair: Upper Control Arm Replacement
Because the ball joint isn’t separately serviceable, replacing the complete front upper control arm assembly is the only permanent fix — greasing or resealing the original joint is temporary.
