you have to take out the everything. remove the back end like you were going to change motors, then pull everything in the front apart except for the front tab. (take the springs off the front it will make reassembly easier.) remove the cone gear if you have AWD and take the tie rod out. then there should be 1 screw on each side of the power switch, take them out and above the front driveshaft holder (right in front of the crystal) there will be a third screw you need to take out. remove the battery cases by sliding them back and lifting them up and then just pull the whole system out. hope taht answers your question. if not: one of them will look broken, it will have a line black line through it or it will have a black ring around it. thats how to tell if it is broken/ blown.
