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.
Why GTA drivers are hit harder: Ontario road salt is exceptionally corrosive to steel ball joint components. Winter road exposure accelerates this failure significantly compared to dry-climate Tesla owners.
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
Service Bulletin SB-20-31-006Applies to: 2018–2020 Model 3, Model Y and Model XTesla 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 present.
NHTSA Recall 21V-835Applies to: 2019–2021 Model 3 and 2020–2021 Model YA 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 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.

Full Suspension DiagnosisUpper/lower control arms, sway bar links, compression rods, and bushings inspected.
2
Latest Revision Parts OnlyWe install the current part revision, not old-stock arms carrying the water-ingress issue.
3
Fastener Torque VerificationSuspension lateral link fasteners checked in light of recall history.
4
Precise Reinstallation to SpecCorrect torque values, tools, and installation sequence followed.
5
Mandatory Wheel AlignmentReplacing any control arm changes suspension geometry — alignment is required after repair.
Grease may temporarily reduce noise, but it does not repair corrosion or restore structural integrity. Replacement 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 alignment is required after the repair.
Does this affect Model Y too?
Yes, similar front suspension noises can appear on Model Y, and the correct repair depends on inspection results and which component is failing. See Model Y ball joint repair.

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.

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.

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.

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.
Alex is a great guy. He took the time to respond by phone and walk me through my options for my Tesla Model Y 2024 and gave me his perspectives as a Tesla owner. Top recommendation in my books for the Toronto area.
I cannot say enough good things about Livio and the team at Radman Auto Repair in Rexdale. We brought in my son’s 2015 Mitsubishi Lancer because the A/C was malfunctioning. We had already been to two other shops, paid for diagnostics, and received different explanations, so we were frustrated and unsure what to do next.
Livio was outstanding. He listened carefully, looked at the issue, and explained everything clearly and in detail in a way that actually made sense. He was able to narrow down what was going on within minutes, without guessing, pressure, or recommending unnecessary work. What really stood out was that he did not charge us another diagnostic fee after learning we had already paid for two separate diagnoses.
Even better, the work was completed the same day, which was a huge relief. It is rare to find a mechanic who is knowledgeable, honest, patient, efficient, and genuinely focused on helping customers understand the real issue before they spend money on repairs.
Livio truly gets it. We are so happy we found Radman Auto Repair and would highly recommend Livio and his team to anyone looking for trustworthy, skilled, and customer-focused service..
My 2015 Honda CR-V was blowing hot air and making noise when the A/C was on. The Compressor and Expansion valve needed replacement due to metal debris in the system.
I rarely write reviews, but I felt it would be wrong not to appreciate Radman for their service, especially after what I went through before finding them.
I’m writing this one month after the repair because I wanted to test my A/C on multiple long trips before recommending them.
One thing I learned from this experience is that many mechanics know how to replace parts, but very *few follow the right procedures* and perform the proper checks. I initially went for a cheaper repair at a local mechanic. The problem came back, and afterward he didn’t seem to know what to do next.
I found Radman through Google reviews without any personal recommendation, so I was taking a chance. They properly diagnosed the issue, explained everything clearly before starting the work, didn’t exaggerate the problem, and charged me a reasonable price. A/C issues can be complicated but they answered all my questions and I honestly haven’t had such a good and detailed conversation with a mechanic in the GTA about an A/C problem. Their knowledge and experience with A/C systems really stood out.
I also had a catalytic converter issue. Another mechanic simply recommended replacing it, which would have cost at least $2,000. Radman explained that considering the age and condition of my 2015 CR-V, such an expensive replacement might not make sense. They gave me the replacement cost but also suggested trying Cataclean first. I tried it, and so far I haven’t had any issues.
After a month and several long trips, my A/C is still working well. It’s rare to find this combination of knowledge, transparency, and honesty.
Thank you, Radman, for the knowledgeable and honest service. I genuinely appreciate it.
I fix my cars myself but I always go to Radman for AC work. Been coming here for years and they do great work and are fairly priced. The guys are honest and reliable. Very clean waiting room too!
Finding a mechanic who actually understands EVs and is completely trustworthy is hard to come by, but Radman Repair is excellent. The service was top-notch, they explained everything to me with so much patience, and the overall experience was a 10/10. 100% recommended!
