Installation Notes and Tips

Install this part in the front upper position only on the listed Lexus applications. Because it uses a press-in mounting type, proper suspension service tools and correct press technique are important for installation. The castle nut and cotter pin hole are part of the fastening design, and the joint is non-greaseable, so routine lubrication is not required.

Fitment includes 2006 Lexus GS300, 2007-2011 Lexus GS350, 2006-2015 Lexus IS250, 2011-2019 Lexus IS350, and 2016-2019 Lexus IS300 in the front upper position. Verify vehicle configuration against the listed application before service.
