Replace a worn front right upper arm and its ball joint in one step with the SKP control arm SK520458, a Control Arm with Ball Joint that arrives with the ball joint already installed. It fits many vehicles, among them the 2002-2010 Lexus SC430, 1998-2005 Lexus GS300 and 2001-2005 Lexus GS430, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list and engine details.
The control arm links the steering knuckle to the chassis and lets the wheel move with the suspension. The ball joint is the pivot that lets the knuckle turn and travel. If a worn arm or ball joint is behind a clunk, wandering steering or a bumpy ride, this one-piece SKP unit replaces both parts together.
Signs this part may need replacing include clunking over bumps, loose or wandering steering, uneven tire wear, and a torn ball joint boot or play at the joint. Diagnose the cause before replacing. Follow the vehicle service information for torque specifications, and check the alignment after installation.
