OE-Style Front Right Lower Control Arm

The Moog RK620571 is a front right lower suspension control arm and ball joint assembly for select Saab applications.

What It Helps Address

• Front-end looseness from a worn lower control arm
• Clunking or knocking from deteriorated bushings
• Uneven tire wear related to suspension wear
• Steering instability caused by ball joint wear
• Suspension noise during braking or turning

Installation Notes

Verify vehicle year, model, and front right lower position before installation. Inspect adjacent suspension components, alignment angles, and fasteners during replacement. Because the ball joint is press-in and the stud uses a pinch-style connection, proper suspension tools and alignment service are recommended after installation.
