What This Control Arm Helps Address

• Rear suspension looseness or clunking from worn arm bushings
• Uneven rear wheel alignment caused by a damaged control arm
• Excessive rear-end movement over bumps or during cornering
• Noise from a fatigued rear right upper rearward suspension link
• Restoring factory suspension geometry after component wear

Installation Notes and Tips

Verify vehicle trim, suspension code, and position before ordering, especially for Buick LaCrosse, Buick Allure, and Saab 9-5 models with H-Arm rear suspension or RPO Code GNE. This arm is not adjustable and does not include mounting hardware, so reuse or source the correct fasteners as required by the vehicle. Because the ball joint is not installed, inspect the mating suspension components and replace any worn related parts during service. Professional alignment is recommended after installation.
