My shower pipes vibrate and make a loud noise when the water is turned too far to the hot side, Unless you turn it all the way hot, then it is scalding. What do I do to fix this and will I have to replace all piping to fix it?

What do I do to fix this and will I have to replace all piping to fix it?"

Vibration's caused by something loose in the valve that's vibrating as the water rushes by. Shut the water off and open up the valve. Check for anything loose in the cartridge or the valve body. Now, with the valve still open turn the water back on for a minute to flush out the supplies. Vibration all better now? Regards, Tom
