Home › Vehicles › Tesla › Tesla Model S Wheel Bearing Part Numbers
The short version
- The Tesla Model S wheel bearing at the front carries Tesla’s own OEM number, 1027121-00-A.
- That number is confirmed in retail listings for 2012 to 2016 and carried through 2021 cars.
- No Moog, Timken or National aftermarket row exists for this car; the OEM listing is the only documented number.
- Ordering a rear through Tesla’s own channels still runs by VIN rather than a shared catalog number.
Tesla never fed its parts into the usual aftermarket catalogs. A Model S wheel bearing job looks nothing like sourcing one for a Corolla or an F-150.
One OEM number, no aftermarket rows
This is the number in retail OEM listings for the Tesla Model S wheel bearing at the front. It is confirmed from 2012 to 2016 and still carried in listings through 2021 cars.
There is no separate Moog, Timken or National row to cross-shop against. The OEM listing stands alone.
How OEM and aftermarket sourcing differ generally is covered on the OEM versus aftermarket page.

Lookups run through the cross reference page.
Front and rear: two different answers
OEM and SKF listings describe one hub assembly covering either the front or rear position. That applies to the Model S and to the 2016 and later Model X.
Ordering a rear through Tesla’s own channels still goes by VIN, not a shared catalog number. Confirm which reading applies, and match the VIN for a rear order through Tesla.
Shared hardware with the Model X
The same hub assembly that covers the Model S also covers the 2016 and later Model X, per those OEM and SKF listings. The two share a platform underneath.
The smaller Model 3 and Model Y run on a separate platform and carry their own numbers. The wider lineup is on the Tesla page.
An EV bearing carries more load, more often
Instant torque and a heavy battery pack put steady load through a Tesla Model S wheel bearing that a gas sedan rarely sees. Regenerative braking adds constant, low-level loading too, rather than the on-off pattern of friction brakes.
What that does to bearing life on EVs generally is covered on the EV bearing cost page.
Diagnosing a Tesla Model S wheel bearing
- Listen for a speed-related hum that changes with road speed, not engine RPM, since there is no engine.
- Weave the car at speed to shift the noise and place the affected corner.
- Check for play with the wheel off the ground at the suspect corner.
- Confirm front or rear before ordering, then decide OEM listing versus VIN-based order.
- Have the VIN ready before contacting a Tesla parts channel for a rear.
The general check routine is on the checking page.
Common questions
What is the Tesla Model S wheel bearing part number?
The front hub assembly carries OEM number 1027121-00-A. It is confirmed in retail listings from 2012 to 2016 and still carried through 2021 cars.
Is there an aftermarket number for this car?
No Moog, Timken or National row exists in the catalogs. The OEM listing is the only documented number.
Does the same part fit the rear?
OEM and SKF listings say the same hub assembly covers the rear too. Ordering through Tesla’s own channels for a rear still goes by VIN.
Does this part fit the Model X?
Yes, per those same OEM and SKF listings, for the 2016 and later Model X, which shares the platform.
Why would this bearing wear differently than on a gas car?
Instant torque and a heavy battery add steady load. Regenerative braking loads the hub more evenly than friction brakes do.
