Ok.... i will post some pics and stuff lucky for you i have the wholefront torn apart replacing the ring and pinion. Give me a few minutes and i will try to show you how.... or if you want look at the manual and see how it all goes i will post pics of what its supposed to look like. If you don't have the manual get on arrma.com and you can view it there the blow ups are in the back along with maintanance instructions.
View attachment 2565 it should look like this if it is functioning properly.
If its stuck it will look something like this(pic below) it needs to be snapped back in place you may not need to disassemble everything you may be able to hold it and snap it back like first pic. If not get on youtube and search arrma kraton servo save you should beable to find some good videos on disassembly and reassembly. If your not allowed youtube ask your mom or dad to do it with you so you don't get in trouble. I assume since your not allowed to upload to the tube your a youngster.
