Rear Half Shaft – 1044164-00-A

Tesla Model 3 Rear CV Axle HalfShaft – Left or Right

High-quality rear CV axle halfshaft for all Tesla Model 3 variants from 2017–2025, including Highland refresh. This replacement for Tesla part number 1044164-00-A is designed to fit either the rear left (driver) or rear right
(passenger) side, making it an ideal solution when your original halfshaft develops noise, vibration, or excessive play.

If your Model 3 makes a clicking or popping noise when turning, especially under acceleration, a worn CV axle is a prime suspect. This new assembly restores smooth power delivery to the rear wheels and eliminates the clunking, clicking, or shudder that often signals a failing CV joint.

Why CV axles fail on Tesla Model 3

• Boot wear & tears – CV boots can crack or split over time, allowing grease to escape and contaminants to enter.
• Instant EV torque – High, repeatable torque loads stress the CV joints more than many ICE applications.
• Road contamination – Water, salt, and debris accelerate wear once the boot is compromised.
• Extended mileage – Daily commuting and highway miles gradually wear the bearing surfaces inside the CV joints.

Our solution

• Direct-fit replacement – Built to replace 1044164-00-A with the correct spline count and length for Tesla Model 3.
• Left or right compatible – One part number fits either rear side, simplifying stocking and ordering.
• Brand new assembly – No core charge, no rebuilding, and no waiting—just install and go.
• All Model 3 trims – Suitable for all Tesla Model 3 variants from 2017 through 2025, including Highland.

Service & coverage

Recommended when you hear clicking, popping, or clunking while turning or accelerating, or when a torn CV boot is found during inspection. Suitable for independent EV shops and DIY owners servicing the rear driveline on any 2017–2025 Tesla Model 3.

Installation note

Verify the axle is fully seated in the drive unit and hub splines, and torque all fasteners to Tesla specifications. Inspect wheel bearings, control arms, and suspension bushings at the same time, as worn components can mimic or contribute to CV noise and vibration.
