ACDelco 45D10879 Front Upper Suspension Control Arm and Ball Joint Assembly - Gold

The ACDelco 45D10879 is an ACDelco Gold (Professional) Front Upper Suspension Control Arm and Ball Joint Assembly, engineered as a high-quality alternative to Original Equipment (OE) suspension components. This assembly combines the control arm and ball joint into a single, ready-to-install unit designed to restore proper steering geometry and suspension performance.

Key Features:

• OE-Quality Engineering: Manufactured to meet specifications for fit, form, and function—compatible with GM vehicles as well as a wide range of other makes and models
• CNC-Machined Housing: Precision-machined for dimensional consistency and long-term durability
• Greaseable Design (where applicable): Allows fresh lubricant to flush contaminants from the joint, reducing corrosion and extending service life
• Impact, Wear, and Fatigue Tested: Each assembly undergoes rigorous testing to ensure reliable performance under real-world conditions
• Backed by General Motors: ACDelco Gold parts are supported by GM, giving you confidence in quality and availability
• Complete Assembly: Control arm and integrated ball joint ship as a single unit for straightforward installation

The control arm serves as the critical link between the steering knuckle and the vehicle frame, while the integrated ball joint enables the pivoting motion necessary for steering and suspension articulation. Replacing a worn or damaged control arm and ball joint assembly restores handling precision, reduces tire wear, and eliminates clunking or wandering associated with failed suspension components.
