Built for the pivot point that lets your front wheel steer and travel over bumps, the Mevotech Supreme Ball Joint MS86508 is a front left lower ball joint engineered in-house with application-specific upgrades aimed at durability and performance. It fits many vehicles, among them the 2007-2020 Lexus GS350, 2006-2019 Lexus GS300 and 2007-2018 Lexus GS450h, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list and engine details.
A ball joint connects the suspension to the steering knuckle, allowing the wheel to pivot as you steer while the suspension moves up and down. As it wears, play can develop at the joint. Clunking over bumps, loose or wandering steering, and uneven tire wear are signs this part may need replacing, though other suspension components can cause similar symptoms, so diagnose the cause before replacing. If a worn front left lower ball joint is the problem, MS86508 replaces it.
