I believe that the pedal axle is part number 32 and is located in the center and between the two side covers. I ran into a similar problem lately with a proform elliptical where bubbles in the pedal axle caused to to break while being used. The pedal axle is held into the crossbars by a bolt located under the covers and then held in place by an adhesive. In order to reach the bolt holding the axle in place you will need to remove the foot pedals and the four screws holding the cover on the the cross bars. After that use a good solvent to break up the adhesive's hold and you should be able to remove the pedal axle without problem. Installing a new pedal axle is much easier than removing the old one so once you get the old one out you shouldn't have any more problems.
