Tesstudio Tesla Model 3 Rear Half Shaft
Replacement rear half shaft / CV axle assembly for Tesla Model 3, part number 1044161-00-D. This drivetrain repair part should be ordered only after confirming your original part number, rear left/right side, axle length, spline shape, boot design, vehicle year, VIN and drive type.
Key Information
- Product Type: Rear half shaft / rear CV axle assembly.
- Part Number: 1044161-00-D.
- Current Page Fitment Text: Fits Tesla Model 3 2017-2019.
- Install Area: Rear drive unit / rear wheel hub halfshaft position.
- Repair Use: For replacement after confirmed axle damage, worn CV joint, torn boot, abnormal vibration, clicking noise or rear drivetrain service.
- Side Verification Required: The URL says rear left, but the product page title does not clearly show LH. Confirm rear left/right before checkout.
- Professional Installation Recommended: This is a drivetrain component and should be installed by a qualified technician or experienced EV repair shop.
When A Rear Half Shaft May Need Replacement
The rear half shaft transfers torque from the rear drive unit to the wheel hub. Replacement is usually considered after proper inspection confirms wear, damage or failure in the axle, spline, CV joint, boot or related mounting area.
- Clicking Or Clunking Noise: Often checked during low-speed acceleration, turning or drive/reverse transitions.
- Torn CV Boot: A damaged boot can allow grease loss and contamination, leading to CV joint wear.
- Vibration Under Load: Rear drivetrain vibration may require inspection of halfshaft, hub, wheel, tire and suspension components.
- Impact Or Repair Damage: Useful after rear suspension, hub, drive unit or collision repair if the original axle is damaged.
- Old Part Match: Compare the removed axle before ordering to avoid wrong-side or wrong-version purchase.
Verify Fitment Before Ordering
Half shafts are model, drivetrain, side and production-version specific. For this product, the page currently states Model 3 2017-2019, while the URL says rear left. Customers should verify compatibility before checkout.
| Check Point | What To Confirm |
|---|---|
| Part Number | Confirm your removed half shaft matches 1044161-00-D or an approved replacement revision. |
| Vehicle Year | Current page text lists Tesla Model 3 2017-2019. Confirm your exact production year before ordering. |
| Side | Confirm rear left / LH or rear right / RH requirement. Do not rely only on the broad product title. |
| Drive Type | Confirm RWD / AWD / Performance configuration and rear drive unit compatibility. |
| Physical Match | Compare length, spline shape, threaded end, CV boot shape, inner cup and outer joint before installation. |
| Service Parts | Confirm whether axle nut, washer, seals, grease or replacement fasteners are required and whether they are included. |
Position This Page As A Repair Part Page
Customers buying a half shaft are usually repair shops, technical Tesla owners or body/suspension repair buyers. The page should be clear, technical and comparison-focused instead of using lifestyle language.
- Lead With Part Number: Show 1044161-00-D in the title, first image and purchase area.
- Clarify Side: Add Rear Left / LH or Rear Right / RH clearly if the part is side-specific.
- Add Fitment Table: Model 3 year range, drive type and side should be visible before Add to Cart.
- Show Real Part Details: Keep full view, spline end, CV boot and threaded nut-end close-ups.
- Add Installation Warning: Professional installation and diagnosis should be recommended for drivetrain repair.
- Remove Generic Q&A: Replace “easy DIY accessory” copy with drivetrain-specific repair questions.
Installation & Service Notes
Rear half shaft replacement is not a simple interior accessory installation. It may require vehicle lifting, wheel removal, brake and suspension access, correct torque procedure, proper seating into the drive unit and careful inspection of seals and boots.
- Diagnosis First: Confirm the half shaft is the failed component before replacement.
- Lift Safety: Raise and support the vehicle correctly before working on rear drivetrain parts.
- Old Part Comparison: Compare the removed axle with the replacement before final installation.
- Do Not Damage Seals: Take care around drive unit seals, hub splines and CV boots.
- Correct Seating: Make sure the inner joint is fully seated in the rear drive unit.
- Correct Fasteners: Replace one-time-use nuts, washers or bolts if required by service procedure.
- Post-Install Check: Confirm no leaks, abnormal noise, vibration, warning lights or wheel-end looseness after installation.
Recommended Extra Image To Add
The current page has only clean product images. To improve conversion, add one more image that shows the rear drivetrain install location and labels the wheel hub side, rear drive unit side, CV boots, spline end and part number.
Compatibility Reminder Before Checkout

Why Replace A Damaged Rear Half Shaft?
| Scenario | With Correct Replacement Half Shaft | With Worn / Damaged Half Shaft |
|---|---|---|
| Torque transfer | Helps restore proper torque transfer from rear drive unit to wheel hub | Worn joints may cause clicking, vibration or inconsistent drivetrain feel |
| CV boot condition | Fresh boot and joint assembly helps maintain grease protection | Torn boot can allow grease loss, contamination and joint wear |
| Repair workflow | Part number and physical shape can be compared before installation | Wrong axle can delay repair and require repeat disassembly |
| Safety | Correct installation supports safe rear drivetrain operation | Incorrect or damaged axle can create unsafe noise, vibration or drivability issues |
| Best use case | Confirmed half shaft failure, damaged CV joint, torn boot or rear drivetrain service | Not recommended to keep driving with confirmed severe axle damage |

Frequently Asked Questions
What is this product?
It is a rear half shaft / rear CV axle assembly for Tesla Model 3, part number 1044161-00-D.
Which Tesla models does it fit?
The current page text lists Tesla Model 3 2017-2019. Customers should still verify VIN, drive type, rear side and original part number before ordering.
Is this rear left or rear right?
The URL says rear left, but the current page title only says rear half shaft. Tesstudio should clarify LH/RH side in the title, main image and product selector. Customers should compare the removed part before checkout.
Is this the same as a CV axle?
Yes. Rear half shaft and rear CV axle are commonly used to describe the axle assembly that transfers power between the rear drive unit and rear wheel hub.
Does it include the axle nut or washer?
The final package contents should clearly state whether axle nut, washer, bolts, seals or other hardware are included. Do not assume extra hardware is included unless listed.
Can I install this myself?
Professional installation is recommended. Rear half shaft replacement may require vehicle lifting, wheel removal, brake/suspension access, special tools, correct torque procedure and post-installation inspection.
Will this fix every clicking or vibration issue?
No. Clicking or vibration can also come from wheel bearings, tires, wheels, suspension links, axle nuts, brakes, drive unit seals or other drivetrain components. Diagnose the issue before replacing parts.
What should I compare before ordering?
Compare old part number, axle length, spline shape, threaded end, CV boot shape, inner joint, outer joint, rear left/right side and drive type.
Does it fit Model 3 Highland or Model Y?
No, not based on the current page text. Do not order for Model 3 Highland, Model Y, Model Y Juniper or Model Y L unless Tesstudio confirms fitment separately.
Is the Tesla vehicle or installation service included?
No. This product includes the selected rear half shaft / CV axle only. Tesla vehicle, tools, hardware, diagnostic work and installation labor are not included unless clearly stated.
