everytime i step on the gas petal i hear a noise coming from the left side

I don't have enough information from your question to give you a good answer. It would help if you were to describe the noise. I'm suspicious that if the noise is really coming from the wheel or tire, the tire or the wheel bearing's defective. You need to find a GM specialist to inspect your truck.
