It is possible to remove without taking off the bulkhead but your gonna need a thin wrench to fit under the arm and go around the ball nut. I have an old schmacher wrench that came in a mi5 and works perfect for this. As another heads up would be a good idea to use threadlock everywhere on metal to metal contact with the screws. The aluminum is very easy to strip out if you use anything other than just snug with the wrench. I already stripped out a couple of places on the car which luckily I was able to fix. Just dont be heavy handed tightning it down. Even as frustrating as the build and those issues are you will be very pleased with how the car drives. Was a half second faster overall than my xpress 2.0 hybrid I usually run which is more times than not the fastest car on the track and I haven't even done any setups on it yet running vta. It corners very quick and squares up fast on hard throttle coming out of corners.
