Detailed Description

This Dorman 526-104 suspension control arm and ball joint assembly is engineered as a direct OE replacement for the front right upper position on 2001-2005 Lexus IS300 models. The stamped steel arm, installed ball joint, and pre-greased construction support consistent suspension geometry and smooth operation. For buyers searching for a Lexus IS300 front right upper control arm assembly or a Dorman 526-104 replacement, this part provides a straightforward service solution for worn upper suspension components.

The assembly uses a press-in ball joint with a threaded stud, includes rubber bushings, and comes with mounting hardware for installation. It is a regular-grade, non-adjustable suspension component with a light suspension grade type, making it suitable for restoring factory-style front suspension performance on the Lexus IS300.

What It Helps Address

• Front-end clunking or looseness from a worn upper control arm assembly
• Uneven steering response caused by suspension wear
• Directional instability during braking or lane changes
• Excessive play from a deteriorated ball joint
• Ride quality issues related to worn suspension pivot points

Installation Notes and Tips

Verify vehicle fitment before installation by matching the application to 2001-2005 Lexus IS300 front right upper suspension positions. Inspect adjacent suspension parts, including bushings, fasteners, and alignment-related components, before completing the repair. Because the ball joint is already installed, this assembly is suited for replacing the complete upper control arm unit rather than servicing the joint separately.

Quality Assurance

Dorman evaluates this replacement assembly through an industry-focused validation process to help maintain smooth ride characteristics, directional stability, and predictable suspension dynamics. The part is built to OE-style specifications for the listed Lexus IS300 applications.
