Installation Notes and Tips

Verify rear fitment by year, make, model, and standard-grade application before installation. Confirm the 26-spline configuration, 5-stud wheel pattern, 114.3 mm bolt circle, and ABS sensor connection match the original part. Clean the mounting surface thoroughly and inspect the knuckle, axle interface, and related brake components before installing the new assembly.

For Toyota Highlander and Lexus RX-series rear hub replacement, compare the original hub dimensions to the WA512365 specifications to ensure correct alignment and sensor operation. Use proper torque procedures during installation to protect the bearing and wheel mounting surfaces.
