What is a lower control arm for 1994 Chevy astro awd van?

The lower control arm on a 1994 Chevy Astro AWD van is a suspension component. It's a horizontal arm, typically made of steel, that connects the vehicle's chassis to the lower end of the front suspension's spindle (or knuckle). It helps locate the wheel and provides support for the weight of the vehicle. Because it's part of the suspension, the lower control arm plays a critical role in handling, ride comfort, and tire wear. Specifically for an AWD Astro, it has to manage the added stresses of all-wheel drive. Damage to a lower control arm can affect alignment, causing handling problems and potentially unsafe driving conditions.
