To ensure your GMC's control arms are in peak condition, regular inspections and maintenance are pivotal. Look for signs of wear such as clunking noises, steering wander, or uneven tire wear, which suggest it might be time to replace them. Extending their lifespan can be as simple as keeping the suspension system well-lubricated and avoiding excessive loads. When selecting new control arms, consider the two primary types available: stamped steel and aluminum, each offering durability and a unique balance between weight and strength. Aluminum arms are lighter, which can improve fuel efficiency, while stamped steel is often more cost-effective. Always opt for high-quality materials to guarantee longevity and remember to adhere to the specific torque specifications during installation to ensure optimal performance.
