2005 Chevy Silverado Steering Noise

Have you hit any curbs lately? My Chevy blazer does this when I crank the wheel too hard or perform tight u-turns. Simply big trucks are not meant to turn so tight, and things start to creak and break. If you hit a curb the wheels on the right side might be out of alignment and its putting stress on the steering arm. I had to replace the lower control arm on both sides for letting my go for too long. In total about $250 and 2 days worth of labor.

No I havent hit any curbs and just slighty turning the wheel it starts to make the sound. What about lubricating?

Thats something to hope for, check your joints and make sure they got enough grease. I remembered one of mine was completely dry, leading to a cracked ball joint on the steering arm.
