Xtra speed 4wheel diff locking axles 

Hello and thanks for the interest in my video, this set of axles seems to be a challenge to mount to anything. I have stopped building anything to use these axles and will buy a injora rock Buggy chassis to do a demo on these axles. That being said, no I have not figured out for sure what i am going to do to set up the pull cable. I am considering using a 90 degree elbow that is found at a bike shop for the brakes on a bike to possition the cable parallel to the chassis frame rails and with the springs removed I feel ill be able to prevent servo strain

I dont think the company that makes these axles sell replacement parts for these. I could be wrong as i have never used this set of axles to this day.

If I said front wheel drive, I apologize and thank you for the correction. I think I was trying to say 4 wheel drive. And you are correct about only the front axle only being able to be used as a steerable axle.

I wish i could answer your question . i am new to the scale and crawler genera. Maybe someone else who has a set of these can chime in and help all of us out. These sets seem to me as throw away units after they break down

Still have not finished the build these were purchased for. So i cant give you feedback on this set and its durability

Unfortunately no. The build has not been abandoned though. I went a step further into this hobby and purchased a milling machine to fabricate my own chassis that these axles will mount onto. Sometime in the near future I do plan on making a new video to show what I got on my table for the build in hopes others can see what's taking so long. I never planed on having to spend 4 or 5 thousand dollars in tooling to build the project that I wanted to use this axle set on, but that's what happened.
