Tesla Wheel Hub Unit | OE: 1044122-00-E

Core Part Information

This is a genuine non-driven front-wheel hub assembly engineered to Tesla's exact production specifications for Model 3 and Model Y rear-wheel drive (RWD) vehicles. It integrates a pre-installed double-row Gen 3 ball bearing, wheel hub, precision 48-tooth ABS encoder ring, wheel studs, and 150mm mounting flange into a single service-ready unit for direct factory replacement. The assembly provides stable wheel support and enables precise wheel speed sensing for ABS/ESP systems without transmitting drivetrain torque.Position: Front Axle (universal fit for both Left and Right sides)Application: Exclusively for RWD (Rear-Wheel Drive) configurations (not compatible with AWD Dual Motor models)Condition: Brand New Genuine Tesla PartSold In Quantity: 1 unitManufacturer Warranty: Tesla Factory Limited Warranty (minimum 12 months)Weight: 3.5 kg (3500 g)

6. Brake Pilot Diameter: 70 mm
7. Material Construction: Forged high-strength steel hub and bearing components with corrosion-resistant finish meeting Tesla's rigorous material standards

Core Features & Performance Attributes

1. Integrated OEM Design: Combines all critical hub components into a single unit, eliminating assembly errors and ensuring consistent factory performance
2. Precision Engineered: Manufactured to Tesla's strict tolerances for optimal rotational balance, minimizing vibration and extending bearing service life
3. Sealed Protection: Advanced labyrinth seals prevent contamination from moisture, dust, and road debris, maintaining bearing integrity in extreme driving conditions
4. Non-Driven Functionality: Specifically designed for front wheels that do not receive torque from the drivetrain, optimized for load-bearing and steering performance
5. Plug-and-Play Installation: Engineered for straightforward professional replacement without requiring specialized modifications or component matching

Important Installation & Safety Notes (Tesla Service Manual Guidelines)

• For professional installation only, following Tesla workshop service protocols (document ID: GUID-52B381EF-B2E3-4A8C-9B58-0F4B6ADD50B6)
• Critical Torque Specifications (Tesla Official):
  • Axle Nut: 300 Nm (221.2 lb-ft) - updated specification (November 2023)
  • Wheel Lug Nuts: 175 Nm (129 lb-ft)Tesla
• Must be replaced as a complete assembly (non-serviceable as individual components)
• Genuine Tesla parts required to maintain vehicle safety, performance, and manufacturer warranty coverage
• NOT compatible with AWD Dual Motor models - verify vehicle drivetrain configuration before installation
