Detailed Product Overview

GS501144 combines the control arm, ball joint, bushings, and dust boot into one service assembly to simplify front suspension repair. The aluminum arm helps maintain factory-style suspension geometry, while the rubber bushings and dust boot support quiet operation and consistent articulation. Mevotech Original Grade parts are engineered as direct replacements for original equipment components, making GS501144 a practical choice for restoring steering response and ride control on Hummer H3 and Hummer H3T models.

Common Problems This Part Addresses

• Front-end clunking or looseness from worn ball joint or bushings
• Uneven tire wear caused by suspension play
• Imprecise steering feel in the front left upper suspension
• Ride quality loss from deteriorated control arm components
• Factory alignment issues after suspension wear

Installation Notes and Tips

Inspect the surrounding suspension hardware, steering linkage, and alignment angles before installation. Because this assembly is non-adjustable and position-specific, confirm front left upper placement on the vehicle before service. A professional wheel alignment is recommended after replacement to restore proper suspension geometry.

Quality Assurance

Mevotech Original Grade parts are built as OE-matched replacement components for fit, form, and function. GS501144 is designed to restore original suspension performance on the specified Hummer applications using a direct-fit replacement approach.
