How do you replace the trap in the drain?

You just replace it. How depends on what type of pipe. Metal pipe, the trap is usually held on with nuts that connect the trap to the sink and the main pipe. On PVC or plastic, it may be glued in place. Rarely is all the drain glued. The piece going up to the sink should have a slip joint right above the trap with a nut. There should be enough of this tube in the trap to allow you to cut the trap out and glue in another one. Cut the trap off the drain line as close to the trap as possible. The drain should be straight at this point. Glue a new one in and reconnect to the sink. The trap will drop down 1/2 to 3/4 of an inch, but there should still be enough pipe to connect. If there is not, an extension is available. Without seeing it, there is no way to give more specific directions.
