Detailed Description

This Dorman suspension ball joint, part number 539-913, is precision-engineered and tested to replace the original equipment on specific front left lower suspension applications. It is a practical choice for Lexus RX350 and RX450h models, as well as Toyota Highlander, Sienna, and Venza vehicles that require a threaded, bolt-in lower ball joint. The steel body, tapered stud, and included dust boot help support a clean, OE-style repair where suspension articulation and steering geometry matter.

Compatible With 2010-2022 Lexus RX350, front left lower; 2018-2022 Lexus RX350L, front left lower; 2010-2022 Lexus RX450h, front left lower; 2018-2022 Lexus RX450hL, front left lower; 2011-2020 Toyota Sienna, front left lower; 2008-2019 Toyota Highlander, front left lower; and 2009-2016 Toyota Venza, front left lower. The Dorman 539-913 is a focused replacement for worn lower ball joints on these platforms, including common service needs on Toyota Highlander front left lower and Lexus RX450h front left lower suspension repairs.

What It Helps Fix

• Front-end clunking or knocking from a worn lower ball joint
• Excessive play in the front left lower suspension joint
• Uneven tire wear caused by suspension looseness
• Steering wander or imprecise front-end response
• Inspection failures related to ball joint wear or boot damage

Installation Notes and Tips

Verify the vehicle’s front left lower position before ordering, since this part is application-specific. Confirm stud thread length, mounting hole layout, and tapered stud engagement during installation. The included castle nut and mounting hardware support a complete repair, and the cotter pin hole allows proper locking once the nut is torqued to specification. Because this is a non-greaseable, standard replacement ball joint, periodic lubrication is not required.

Quality Assurance

Dorman states this suspension ball joint is precision-engineered and rigorously tested to provide a reliable OE replacement on the listed vehicles. The part number 539-913 is built to meet the demands of everyday suspension service on Lexus and Toyota applications.
