Tesla Model 3 Rear Half Shaft / CV Axle
Replacement rear half shaft assembly for compatible Tesla Model 3 vehicles. Start with P/N 1044161-00-D, then verify your VIN, drive configuration and original axle before ordering.
Five Checks Before You Order a Rear Half Shaft
Replacement drivetrain parts can look nearly identical while differing in production revision, side, length or drive-unit application.
Compare 1044161-00-D with the original part reference.
Confirm vehicle production information before purchase.
Confirm RWD / AWD / Performance application.
Confirm whether your repair requires left, right or a non-sided axle.
Compare shaft length, splines, boots and joint housings.
Compare the Outer Spline and Threaded End
The wheel-side joint connects the half shaft to the rear hub. Compare the threaded end, spline profile, CV-joint housing and boot shape before installation.
- Threaded axle end
- Outer hub spline
- Outer CV joint
- CV boot profile
- Check hardware requirements separately
Check the Inner Joint Before the Repair Starts
The drive-unit side must match the intended drivetrain application and seat correctly in the rear drive unit. Similar-looking revisions should not be treated as automatically interchangeable.
- Inner spline profile
- Joint housing geometry
- Boot shape and clamp position
- Shaft diameter and overall configuration
- Drive-unit compatibility
Part Number Is Important — Physical Comparison Is Still Required
Production changes can occur within the same model family. Compare your original axle with the replacement before completing the installation.
- Spline count and profile
- Threaded section
- CV-joint housing diameter
- Boot and clamp configuration
- Overall shaft length
Order by Part Data — Not by Model Name Alone
Rear half shafts can vary by production revision and drivetrain. Treat general model-year information as a starting point, not the only compatibility check.
Symptoms That May Require Half-Shaft Inspection
These conditions can justify drivetrain inspection, but none of them alone proves that the half shaft is the failed component.
Grease loss and contamination can contribute to CV-joint wear.
Requires diagnosis of axle joints, hub, suspension and related drivetrain parts.
Half shaft is one possible cause among tires, wheels, bearings and drivetrain components.
Inspect the axle after wheel-end, suspension, hub or collision damage.
Know What Is Included Before the Vehicle Is Disassembled
Replacement hardware requirements can vary by service procedure. Confirm all required parts before the repair appointment.
This Is a Drivetrain Repair — Not a Simple Bolt-On Accessory
Rear half-shaft replacement may require safe vehicle lifting, wheel-end disassembly, suspension access, drive-unit seal care, correct seating and vehicle-specific fastener procedures.
Questions Before Ordering P/N 1044161-00-D
What is this part?
It is a rear half shaft / CV axle assembly used between the rear drive unit and rear wheel hub on compatible Tesla Model 3 vehicles.
What is the listed part number?
The listed reference is P/N 1044161-00-D.
Which Model 3 years does it fit?
The current Tesstudio listing states Model 3 2017–2019. Because half-shaft application can vary by production date and drivetrain, confirm your VIN and original part reference before ordering.
Is 1044161-00-D rear left or rear right?
Available parts references are not fully consistent on side designation. Confirm the application for your specific vehicle before ordering rather than relying on left/right assumptions.
Is a half shaft the same as a CV axle?
In this application, rear half shaft, rear CV axle and rear drive shaft are commonly used to describe the axle assembly connecting the rear drive unit to the wheel hub.
Does it fit every RWD, AWD or Performance Model 3?
Do not assume universal drivetrain compatibility. Verify your VIN, drive configuration, original part number and physical axle details.
Does the axle nut come with the half shaft?
Current photography shows a nut on the threaded end, but final package contents should be confirmed before purchase. Do not assume additional hardware is included unless listed.
Will this fix clicking or vibration?
Only if diagnosis confirms that the half shaft or CV joint is the cause. Similar symptoms can originate from wheel bearings, tires, wheels, suspension, fasteners or other drivetrain parts.
Is professional installation recommended?
Yes. Rear half-shaft replacement involves drivetrain, suspension and wheel-end service and should be completed by a qualified technician or experienced EV repair shop.
What should I check after installation?
Confirm correct joint seating, required fastener procedures, undamaged CV boots and the absence of leakage, abnormal vibration or drivetrain noise.
