Welcome to GMTC. It could be anything. Is it 4x4? It could be a wheel bearing. It could be mud in the rims. It could be a front diff issue. Or it could be worn steering components. We need more details. What speed does it happen at? Does the wheel return to center by itself when you turn a corner and let the wheel go? Does it make any noise?
It is not a 4x4. It happens at all speeds and makes a slight clunking noise
