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.\u003c\/p\u003e\u003cp\u003eThis part cross-references Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eWheel bearing noise from a worn rear hub assembly\u003c\/li\u003e\n\u003cli\u003eExcessive wheel play or looseness at the rear axle\u003c\/li\u003e\n\u003cli\u003eVibration or rough rotation caused by bearing wear\u003c\/li\u003e\n\u003cli\u003eHub fitment issues after original component damage\u003c\/li\u003e\n\u003cli\u003eService replacement for a failed Tesla Y rear hub\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eConfirm 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.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eInMotion manufactures this hub assembly using strict quality-control criteria and OE data-based measurements to support consistent fitment and performance.
