Expert Reply:
To determine the location for the front and rear hangers on your tandem axle trailer you will first need to make sure that you have the correct center point for your equalizer hanger.
The center point of your equalizer hanger needs to be located where you will have 60 percent of the frame of the trailer in front of the center of the equalizer hanger and 40 percent behind the center of the equalizer hanger. For example, if the trailers frames length is 18 feet, then the center-line location for the equalizer hanger will be 10.8 feet from the front of the trailer and 7.2 feet from the back.
This is where to start with when picking out axle locations for a tandem axle trailer. If it's a boat trailer with an outboard engine you may want to start with the axles further back. You will need to determine the tongue weight of the trailer and then check out the picture I attached if the tongue weight is anything other than 10 percent of the total trailer weight.
