Earlier front upper control arm reference family
Match the side and revision before the vehicle is disassembled
This U-shaped front upper control arm listing separates the left 1044321 family from the right 1044326 family. The current description references several E, F and J revisions, so a LEFT or RIGHT choice alone does not replace a part-number and supersession check.
Before checkout: The product selector sells a LEFT or RIGHT option. A left/right pair is not stated as included, even when product media show the complete arm from several angles.
What makes this an exact-reference repair
Left and right are mirror-specific
The left 1044321 family and right 1044326 family have different geometry and should not be treated as interchangeable.
Revision letters still matter
The listing references E, F and J revisions. Confirm the revision or an approved supersession with current vehicle-specific information.
Symptoms require inspection
Creaking, looseness or tire wear may come from several suspension components. Diagnose the upper arm before buying it.
Use the side selector only after reference confirmation
The live options are LEFT and RIGHT; the detail below explains the part-number families currently referenced by this page.
LEFT: 1044321 reference family
The current listing references 1044321-00-E, 1044321-00-F and 1044321-00-J. Confirm the exact revision or valid replacement before checkout.
RIGHT: 1044326 reference family
The current listing references 1044326-00-E, 1044326-00-F and 1044326-00-J. Confirm the exact revision or valid replacement before checkout.
What the right upper arm choice prevents
A wrong-side order
Matching LH or RH first avoids receiving a mirrored assembly that cannot occupy the diagnosed position.
Revision guesswork
Checking the full reference gives the installer a clearer basis than relying on vehicle name and appearance alone.
An incomplete diagnosis
A physical inspection helps separate upper-control-arm wear from nearby joints, links, tires or mounting hardware.
Product and fitment details
Upper-arm installation needs the correct setup position
Verify before removal
Confirm vehicle configuration, side, reference and approved supersession before the original arm is removed.
Compare every mounting point
Check the U-shaped profile, bushings, ball-joint end, brackets and sensor-related features against the removed component.
Follow current service data
Ride-height setup, torque values and post-repair alignment checks are vehicle-specific and should be handled by a qualified technician.
Part and origin transparency
The product media show a black U-shaped control arm with bushings and a joint, but no Tesla-branded retail packaging or manufacturer certificate. This page therefore does not claim documented genuine Tesla manufacture. Ask TESStudio for origin or supersession documentation if it is required for the repair.
Compare other verified Model 3/Y control-arm families
These products cover different designs, references or suspension positions. They are comparison links, not automatic substitutes.
1044321 / 1044326 upper control arm FAQ
Does the order include both sides?
A pair is not stated. Choose the required LEFT or RIGHT option in the live selector.
Which family is left and right?
The page references 1044321 for the left side and 1044326 for the right side.
Do the E, F and J endings mean the same thing?
They are different part revisions. Confirm the exact revision or a documented supersession before ordering.
Will it fit every Model 3 or Model Y?
No universal fit is claimed. Vehicle build configuration, the old part number and current service information take priority.
Can creaking alone confirm this arm has failed?
No. Several suspension components can produce similar symptoms, so the vehicle should be inspected first.
Is professional installation recommended?
Yes. Upper-control-arm work requires safe lifting, correct component positioning, specified fastener procedures and an appropriate post-repair check.
Confirm the component, side and full reference before checkout
A precise match and a professional repair plan protect both the installation and the decision behind it.
