    You don't need a new bulkhead. Just replacing ring and pinion gear of the diff will solve the clicking problem. There are several threads about diff shimming.
    That set is quite cheap by the way.

    The little 1/16 guys are prone to stripping the ring and pinion. I replaced and shimmed mine when it started clicking..... stripped the new one pretty quickly after that. I now wait till there good and destroyed before replacing them. You ARE NOT GOING TO HURT ANYTHING by continueing driving with the clicking. At the moment both my front and rear are shot, but still drives and is a lot of fun.

    a stripped pinion and diff will just give you poor performance and the bugging of the noise it did for me till my parts came in to fix and replace them. Your rc will not travel at full speed since the diffs is slipping it can cause the motor to spin a little faster since it does not have the diff and pinion grabbing.

    is it bad for the motor to spin that fast though ?

    The VXL ESC has a rev limiter.


    If you are so hesitant to run it, don't.
    Whatever it is I just said... I could be wrong.

    then its done for you need a new pinion and diff ring. best to get a new seal kit was well.

    the motor can heat up which is not a good thing is what you will be concerned about, when i ran mine like that to finish off the diff and pinion i took it easy on the throttle little to not over heat and free speed the motor.

    Yeah, when the wheels stop turning NOW its time to fix it LOL. Unless your made of money I would sugest U start to learn to repair them yourself. Its part of the hobby, these arent toys.

    Yup... same parts except for maybe the blue plate.
    Shipping to Canada might kill the deal though... didn't know you were in Canada.

    well guys my diff is stripped again. I'm not really sure as to why I'm using 2s not even 3s.. this time i think the front is gone as well. my local hobby shop has traxxas part number 7078 for 23 dollars as they are all out of the ring and pinion (7079). should i just go with the complete assembly or should i keep looking ?

    78 does not include the pinion... which is what you need.

    Did you shim?
    How tight is your slipper?

    Your slipper may be too tight for your driving style.

    if you broke it again, you need to to work on your driving skills. These aren't indestructible like most people think. You can't land them with the throttle on (can't land any with the throttle on) Can't slam them into solid objects with the power on, can't backflip them and expect the diffs to live etc.

    Also, the gears in the diff themselves can go so if you replace the ring and pinion and it still clicks, you probably need to replace the internal spider gears.

    That all depends on how you have it built.


    When mine was the most durable I had no hesitation to hand the controls over to anyone. They would land full throttle, hit random stationary objects, ramp it up into trees, ect, ect, and would never let off the throttle. It always was drivable after the bash session. Now, don't get me wrong... it was not indestructible, just more prepared for the abuse. However, I would like to add that I never stripped out a differential until I went to 3S.
    Whatever it is I just said... I could be wrong.
