Why do my truck make a very loud popping noise when turning to the left or the right

Time for an inspection at a tire and alignment shop. They'll start by looking at the ball joints. If you have a 4wd model, front outer universal joints can cause a popping noise too. You can identify that by putting it in 4wd, turning, and driving forward. If the steering wheel gets forced back to center as the wheels turn, one of the universal joints is binding.
