Tesla Model 3 Front Suspension Squeaking or Creaking Over Bumps? Upper Control Arm Fix & 2026 Cost
Short Answer: A creak like an old mattress, or a dry squeak when you turn the wheel at parking-lot speed or roll over a speed bump, is most often a dry, corroded front upper control arm (FUCA) ball joint. It can show up on a Model 3 of any year once the miles add up, but it is most common on 2018–2020 cars, which is why Tesla wrote service bulletin SB-20-31-006: water can find a path into both upper ball joints, cause surface corrosion, and make the suspension creak. Tesla calls it a noise-only condition, not a safety failure. Your options: a grease-needle injection that owners use as a temporary silencer (roughly $10–$25 in supplies), Tesla Service replacing both arms (owner reports range from about $200 when labor is waived to $570–$650 when it isn't), or a DIY swap to the latest Tesla arms or MEYLE HD arms (around $350 for the pair) plus an alignment check.
My Model 3 is a June 2020 build with a little over 76,000 miles on it, running HW3 and the Intel Atom infotainment computer, on 235/45R18 tires that I keep at about 38 psi. Whatever year your Model 3 is, there's one noise worth knowing about: a creak from the front suspension that shows up at low speed, gets louder when you turn, and makes a $40,000 car sound like a screen door. Early cars like mine get it most often, but owners of later builds report it too, and most of the time it comes from the front upper control arms.
Below I go through how to confirm the noise is really the upper control arm, what Tesla's own bulletin says about why it happens, and four fixes from cheapest to permanent, with 2026 cost ranges based on owner invoices. The photos are from my car, taken while checking the front wheel wells with a flashlight.
How to Diagnose the Squeak: Upper Control Arm vs. Lower Links vs. Aero Wheel Covers
The Model 3 front suspension (2017–2023 cars) has one upper control arm per side and two lower links. Tesla's service manual calls them the front lower lateral link (the forward one) and the front lower compliance link (the rearward one, with the large rubber bushing). Add the stabilizer bar end link, the strut and the plastic Aero wheel covers, and there are several things that can creak, click or clunk. Check them in this order.
Step 1: Take the 18-inch Aero covers off first
If you have 18-inch wheels with Aero covers, as I do, remove them before you blame the suspension. A loose cover or a broken retaining clip can tick or click once per wheel revolution, and that's easy to confuse with a suspension squeak. Tesla's own guidance is simple: grip the cover with both hands and pull it straight toward you to release the clips. Don't pry it off with a screwdriver. Drive a short loop without the covers. If the noise is gone, you've found it.
Step 2: The stationary steering test
Parked with the driver's door open so I can hear the front wheel well while I turn the wheel slowly from lock to lock.
Park on a hard, level surface, put the car in Park, and open the driver's door or lower the window. Slowly turn the steering wheel from full left to full right and back. A dry upper ball joint usually creaks or groans as the knuckle rotates under the car's weight. Turning the wheel while parked loads the joints more than almost anything you do while driving, so this test catches a lot of them. If you have a helper, ask them to crouch by each front wheel and listen, because the noise usually comes from one side first.
Step 3: The 5 mph rolling test
Find an empty parking lot or garage, close the windows and turn off the climate fan and music. Roll at about 5 mph through tight figure eights, then go slowly over a speed bump at an angle so one front wheel compresses before the other. What each noise usually means:
- Creak or squeak that follows steering input and body movement at low speed: usually the upper control arm ball joint.
- Dull clunk or knock over bumps, or when you brake and then release: more often the lower compliance link bushing, a stabilizer bar end link, or something loose. Have it inspected rather than greased.
- Rhythmic tick that speeds up with the car: look at the wheel covers, a stone in the tread, or a brake dust shield touching the rotor.
Another quick check: push down hard on the front fender a few times to bounce that corner. Owners report Tesla technicians confirming FUCA creak with this exact test.
Step 4: Look at the parts
Looking up past the tire on my car. The black upper control arm sits across the top, the round rubber ball joint boot is in the center, and the silver part below it is the top of the aluminum steering knuckle, where the pinch bolt clamps the ball joint stud.
With the wheels turned all the way to one side, a flashlight shows most of the upper arm from inside the wheel well. Here's what I check on my own car: whether the rubber boot is torn or split, whether there's rust bleeding out from under the boot, and whether grease is leaking or there's crusty dirt around the joint. A torn boot means water and grit are getting in, and that joint is heading for replacement whether it's noisy yet or not.
The same arm from a different angle. The inner end mounts to the silver bracket on the left, and the ball joint and boot are at the outer end on the right. The thin black wire clipped along the arm is the wheel speed sensor harness, which has to be unclipped before the arm can come out.
Why Model 3 Upper Control Arms Creak (and Why Early Cars Get It Most)
The Tesla service bulletin that covers the creak is SB-20-31-006, "Reseal Front Upper Control Arm Ball Joints." Revision 1 came out in November 2020, and revision 3 was dated July 2, 2021. It's published in NHTSA's manufacturer communications database. In plain English, it says:
- Affected cars: certain 2018–2020 Model 3, Model Y and Model X vehicles. The years are an approximation, and Tesla checks the actual list by VIN.
- Cause: a water ingress path into both front upper control arm ball joints, which over time can lead to surface corrosion.
- Symptom: a creaking sound from the front suspension when steering at low speeds and under high loads.
- Severity: Tesla calls it a noise (NVH) condition only, and says it does not cause premature failure of the ball joints.
- Tesla's correction: clean and prime the area around each ball joint, then seal the seams with urethane so water can't get in. The bulletin specifically says not to put urethane on the ball joint boot itself. Book time is 0.30 hours for a Model 3.
The resealing is preventive. It stops new water from getting in, but it can't remove corrosion that's already there. That's why owners whose joints are already creaking usually end up with new arms. Very early cars had a separate bulletin, SB-18-31-002. It applied to Model 3s built roughly July 1 to October 3, 2017, which could get a vibration noise from the upper arms at 65 mph and above, and the fix was replacing both arms.
Does mileage predict it? Tesla doesn't publish a mileage figure. The owner reports I read ranged from about 36,000 to 99,000 miles, and plenty of cars never creak. Climate and road salt probably matter more than the odometer.
Other build years:
- 2017–2020: the core population for SB-20-31-006, and the cars that now have the most miles.
- 2021–2023: not listed in the bulletin, but there are owner reports of the same creak on 2022 cars. Tesla has revised the arm several times. Early arms went through revisions ending in letters up to -J (part numbers 1044321 left and 1044326 right). The current service manual also lists newer part numbers, 1288321/1288326 and 1188321/1188326, which need an extra spacer on Tesla's setup tool.
- 2024+ Highland: it uses a revised front suspension, and aftermarket upper arms made for 2017–2023 cars are listed as not fitting it. Most Highlands are still within the basic warranty, and I haven't seen enough high-mileage reports to say whether the problem carried over.
4 Ways to Fix the Tesla Model 3 Control Arm Squeak (Cheapest to Permanent)
Option 1: Rule out the free stuff (Aero covers and lug nut torque)
Pull the Aero covers as described above and check the lug nuts. Tesla's spec for the Model 3 is 129 ft-lb (175 Nm) with a 21 mm socket, tightened in a star pattern. Use a real torque wrench, not an impact gun. A wheel that was put on loosely after a tire shop visit can click and creak too. This takes 15 minutes and costs nothing if you own a torque wrench.
Option 2: The DIY grease needle trick (temporary silencer)
This is an owner workaround, not a Tesla procedure. You fit a grease gun with a needle-style injector tip (owners commonly use an 18-gauge needle), slip it under the edge of the ball joint boot or push it through the boot, and pump in a small amount of waterproof grease (lithium or marine grease) until the boot just starts to swell. Some owners then dab RTV silicone over the pinhole.
- Pros: cheap (roughly $10–$25 for a needle adapter and a tube of grease, by my estimate), takes about 20 minutes per side with the wheel turned, and no alignment is needed.
- Cons: results vary a lot. On owner forums I've seen it last a few weeks for one person and about two years for another before the creak came back. Every hole you poke in the boot is a new way for water to get in, which is the same problem that started this. Overfilling can also pop the boot off its seat.
- Don't use it if: the boot is already torn, or the joint has any play (see the safety section below). Grease quiets a dry joint. It doesn't tighten a worn one.
Treat it as a way to get quiet until a planned replacement, not as the fix.
Option 3: Book Tesla Service
Model 3 cars come with a Basic Vehicle Limited Warranty of 4 years or 50,000 miles, whichever comes first. A 2020 car like mine is past both limits, so the bill is yours unless Tesla decides to help. Owner reports from the last few years go both ways:
- Many owners got both arms replaced for parts only, with labor waived as goodwill. Parts ran about $90 per arm, and totals were roughly $195–$275 including tax and, in some cases, a diagnostic fee.
- Other owners were charged labor. Reported quotes were about $570 (2024) and $649 before tax including diagnosis (early 2026). Diagnostic fees alone were reported at about $76–$105 if you decline the repair.
There's no published policy, so don't assume you'll get the low price. In the Tesla app, go to Service > Request Service, pick the closest suspension or noise category, and be specific. Something like this works:
"Creaking from the front suspension when turning at low speed and over bumps. It also creaks when I turn the wheel while parked. This matches front upper control arm ball joints / SB-20-31-006. Please check whether that bulletin applies to my VIN and quote both front upper control arms, parts and labor, before any work."
Attach a short clip of the noise if the app lets you. A recording of the creak gives the advisor something to listen to before you even arrive. Ask in writing whether an alignment check is included, since that's often a separate line item.
Option 4: Full DIY replacement with revised Tesla or MEYLE HD arms
This is the permanent fix. The replacement choices are the latest Tesla revision, or MEYLE HD arms (70-16 050 0009/HD left, 70-16 050 0010/HD right). The MEYLE arms are listed for 2017–2023 Model 3 and pre-2025 Model Y, not for Highland. MEYLE says its arm body is a one-piece forged aluminum design closed at the top so water can't get in, and it uses a larger ball stud. US Tesla-accessory retailers had the pair at about $350 when I checked in October 2026. Whatever arm you buy, compare it against the part number on your old arm before you start.
From the outside of the wheel well, the arm runs back toward the body, and the ball joint sits right above the tire. The inner mounting bolts can't be reached from here, which is why the job starts in the frunk.
Here's an overview of Tesla's service manual procedure for 2017–2023 cars (per side). Book time is 0.72 hours, and Tesla lists it as not mobile-capable.
- Clear the front compartment: remove the rear underhood apron, the cabin intake duct, the hood latch cover and the underhood storage unit (the frunk tub). Then swing the shock tower cover aside and lift the cowl screen panel. The first few steps are the same ones that expose the 12V battery, which I covered in my Model 3 12V battery replacement guide. The procedure doesn't require disconnecting low-voltage power, but you'll be working right next to the battery.
- Mark the four upper mount bolts on the shock tower with a paint pen so the assembly goes back in the same spot.
- From below, remove the wheel, unclip the wheel speed sensor harness from the arm, and remove the ride height sensor arm if your car has one. Then remove the stabilizer link nut, the upper arm-to-knuckle pinch bolt and nut, and the strut-to-lower-link bolt.
- Unbolt the spring and damper assembly from the shock tower and pull it outboard until the upper arm mount clears the wheel arch liner. The arm's inner bolts are trapped against the body otherwise, so this is how it comes out.
- Swap the arm on the mount. Before tightening the two arm-to-mount bolts, Tesla sets the arm at ride height with a dedicated FUCA tool. Without the tool, the manual's fallback is a 60 mm measurement between the mount's threaded hole and a ruler laid across the arm. If you tighten these bushings with the arm hanging at full droop, they're preloaded and can wear early.
Tesla's torque specs from the service manual:
| Fastener | Torque | Note |
|---|---|---|
| Upper arm to mount (x2) | 36.9 ft-lb (50 Nm) | Tighten at ride height setting |
| Upper arm to knuckle | 41.3 ft-lb (56 Nm) | New nut |
| Mount to body, larger bolts | 45.7 ft-lb (62 Nm) | 15 mm, line up paint marks |
| Mount to body, smaller bolts | 25.8 ft-lb (35 Nm) | 13 mm |
| Stabilizer link to strut | 72.3 ft-lb (98 Nm) | New nut |
| Strut to lower link | 78.2 ft-lb (106 Nm) | Torque at ride height |
| Lug nuts | 129 ft-lb (175 Nm) | Star pattern, wheels on ground |
Afterward, the manual sends you to its alignment requirement table to decide between a steering (EPAS) alignment check and a full four-wheel alignment check. Since the arm-to-mount position changes, budget for an alignment check either way. Highland (2024+) cars have their own procedure in the 2024 service manual, so don't use these steps for them.
Repair Options & 2026 Cost Comparison
| Repair Method | Typical Cost (2026) | How Long It Lasts | Best For |
|---|---|---|---|
| Remove Aero covers, torque lug nuts | $0 with your own torque wrench | Permanent if the cover or wheel was the cause | Ticks and clicks that follow wheel speed |
| Grease needle injection | About $10–$25 in supplies (estimate) | Weeks to about 2 years (owner reports) | Dry joint with no play, as a stopgap |
| Tesla Service, both arms | About $195–$275 with labor waived; $570–$650 with labor (owner reports) | New arms; years, depending on climate | Most owners, especially if the advisor waives labor |
| DIY with MEYLE HD or latest Tesla arms | About $350 for MEYLE HD pair, plus an alignment check | Long term; MEYLE lists a 4-year warranty on HD parts | Experienced DIYers with a lift or solid jack stands |
Prices are from owner invoices and retailer listings, not a Tesla price list, and labor rates vary a lot by region.
Is It Safe to Drive With a Squeaky Control Arm?
A dry, creaky joint that's otherwise tight is a noise problem. That's how Tesla's bulletin classifies it, and plenty of owners drive with it for months. Play in the joint is a different situation. Stop putting it off and book an inspection if you notice any of these:
- A clunk (not a creak) over bumps or when you change direction from forward to reverse.
- The car wanders on the highway, or the steering wheel is suddenly off-center.
- Uneven tire wear, especially on one edge of a front tire. While you're down there, check your pressures too. My tire pressure and TPMS guide covers the cold-weather numbers.
- Movement you can feel when the front is lifted and you rock the tire hard at 12 and 6 o'clock, or a torn boot with rust showing.
After any suspension job, get the alignment checked. If Autopilot features act strangely after an alignment, or the car keeps showing calibration messages, the touchscreen Service menu has a Camera Calibration option where you can clear calibration and let the cameras relearn while you drive. I walk through that in my Autopilot Cameras Unavailable fix guide.
The Service menu on my Model 3. After suspension work, I check Wheel & Tire to make sure the wheel setting is still correct, and Camera Calibration is there if Autopilot needs to relearn after an alignment.
Frequently Asked Questions
Will Tesla replace the upper control arms for free?
Under the 4-year/50,000-mile basic warranty, a defective arm should be covered. After that, it's up to the service center. Many owners report Tesla waiving labor and charging only for parts, and others report paying full labor. It costs nothing to ask whether SB-20-31-006 applies to your VIN and whether labor can be waived. Just don't count on it.
Do I have to replace both sides?
Only one side may be creaking, but Tesla's earlier bulletin replaced both arms, owner invoices almost always show a pair, and MEYLE recommends pairs as well. Both joints have had the same miles and the same water exposure, so the quiet side is often next.
Can I just spray WD-40 or silicone on the joint?
Spray on the outside of the boot doesn't reach the ball and socket, which is where the corrosion is, so at best it quiets a squeaky bushing for a day or two. If you want a stopgap, the grease needle method at least puts grease inside the joint. Replacement is the real fix.
Do I need an alignment after replacing the upper control arms?
Tesla's procedure ends by checking the alignment requirement table, and depending on what was disturbed that means a steering alignment check or a full four-wheel alignment check. Some owners skip it when the steering is centered and the tires wear evenly. On a car with 76,000 miles like mine, I'd rather pay for the check than wear out a set of tires.
If you're working through other problems on an older Model 3, I've also written up winter range loss fixes and a guide to charge cables that won't unplug.
