Tesla 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.

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. The front upper control arm ball joint has a well-documented design flaw that allows water ingression, leading to corrosion, noise, and eventually a safety risk if ignored.
What's Actually Failing
The front upper control arm connects the front wheel's steering knuckle to the chassis, allowing the wheel to move up and down over bumps while maintaining precise steering geometry. At the end of this arm is a ball joint — a spherical bearing that permits smooth multi-directional movement.
Tesla's original design used a hybrid steel and fibre-reinforced plastic construction, with a plastic cap over the ball joint. The problem: the lip of that cap sits at the lowest point of the arm. Water drains onto the arm, seeps under the cap, and gets trapped — washing out the grease over time, causing corrosion, and creating the characteristic squeak or creak.
Why GTA drivers are hit harder: Ontario road salt is exceptionally corrosive to steel ball joint components — winter roads accelerate this failure significantly compared to dry-climate Tesla owners. Critically, the ball joint on the Model 3's upper control arm is not serviceable separately — Tesla supplies the arm as a complete assembly, so when the ball joint fails, the entire arm must be replaced.
Tesla Service Bulletins & Recalls
This isn't a fringe issue — Tesla has formally acknowledged the problem and issued multiple service documents.
Service Bulletin SB-20-31-006
Applies to 2018-2020 Model 3, Model Y, and Model X. Tesla acknowledged water can enter the ball joint and cause corrosion and creaking. The reseal fix may not reverse existing corrosion — full control arm replacement is the permanent solution once noise is already present.
NHTSA Recall 21V-835
Applies to 2019-2021 Model 3 and 2020-2021 Model Y. A separate but related recall involving front lateral link fasteners that could loosen and cause loss of vehicle control — this should be checked on affected vehicles.
Tesla has revised the upper control arm multiple times. When we replace your control arm, 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.
How It Progresses if Ignored
Water ingress begins → corrosion and squeak develop → the joint wears and clunks, and alignment can no longer be maintained → if fully ignored, the joint can separate and 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.

Frequently Asked Questions
Can I just grease the ball joint?
Grease may temporarily reduce noise, but it does not repair corrosion or restore structural integrity. Replacement of the full upper control arm is the permanent fix.
Is the squeak a safety issue?
A squeak is an early warning. If ignored, it can progress to clunking, looseness, poor alignment, and potential joint separation.
Do I need an alignment after replacement?
Yes. Replacing the upper control arm changes suspension geometry, so an alignment is required after the repair.
Does this affect the Model Y too?
Yes. Similar front suspension noises can appear on the Model Y, and the correct repair depends on inspection results and which suspension component is failing.
