Detailed Description

This InMotion wheel bearing and hub assembly is built for the rear position on Tesla Y models from 2020 through 2022. The hub uses OE-based dimensions including a 142 mm flange diameter, 106 mm total hub height, 114.3 mm hub centerbore diameter, and 70.1 mm hub pilot diameter to support accurate installation and proper wheel location. The ball bearing construction and driven hub design are specified for the application, while the 30-spline configuration and 5-bolt flange help match the original driveline interface. WA1044123-00-B is a direct replacement option for Tesla Y rear hub service where the original assembly has worn or failed.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Wheel bearing noise from a worn rear hub assembly
• Excessive wheel play or looseness at the rear axle
• Vibration or rough rotation caused by bearing wear
• Hub fitment issues after original component damage
• Service replacement for a failed Tesla Y rear hub

Installation Notes and Tips

Confirm rear-position fitment before installation on 2020-2022 Tesla Y Standard Grade vehicles. Verify spline count, flange bolt pattern, lug thread size, and hub dimensions against the removed part before assembly. Because no ABS sensor or wiring harness is included, transfer or reuse related components only if they are in serviceable condition and match the vehicle configuration. Torque all fasteners to Tesla specifications and inspect adjacent suspension and axle components during service.

Quality Assurance

InMotion manufactures this hub assembly using strict quality-control criteria and OE data-based measurements to support consistent fitment and performance. The part is supplied new and built for direct replacement use in the specified Tesla Y rear application.
