Verify vehicle year, make, model, and trim before ordering, since fitment is specific to listed Lexus RX, Lexus TX, and Toyota Sienna applications. Because the assembly is greaseable and pre-greased, follow standard chassis lubrication procedures after installation and torque all supplied fasteners to factory specifications.
