    Broke a part from the Driveshaft...

    Hello!

    Im new here and i am a new owner to a stampede 4x4 vxl. I have been using 8.4 volt battery packs on the car but i wanted more power in it and i bought traxxas original 9.6 volt battery pack and it did wheelies.
    today i decided to change the wheelie-bar to max and i then pulled full throttle and after 10 seconds of driving it just stopped and i just saw the front tires spinning but not the rear tires. When i took a look at it i saw that a part from the rear driveshaft was broken. it was on the left side of the car, right next to the body, or more precisely, it was the Differential output yokes, heavy duty (2)/ screw pin (2). thats what it said in the manual. i dont know why it got broken like that and now i dont know how to replace it.

    Its not uncommon for them to brake, loosening your slipper clutch a little can really help on drivetrain longevity.

    Hi MrSweden, Welcome to the forums and the addiction! The output yokes breaking is a common issue with the rear-end of the truck. Mine broke after a few trips through grass on a 2s lipo pack. I recommend the Tekno RC M6 Drive Shafts. They are a simpler design and steel construction.

    Good luck, and make sure you post some pics of your truck!

    MIPs are great. No issues since I use them. I used Red Loctite for the joints and blue for everything else. No set screw came lloose til now. Awesome product

    Yes just let the loctite sit for 24h and it will keep the screws in place. No problem.

    MIPs are much stronger than Teknos but also more heavy and more expensive. I went with MIPs and like them a lot

    hi thanks for all your answers. i bought a new yoke. i will look that up about the MIP and the tekno and see who is selling them. i was just wondering if i need to change the slipper clutch often? now when i drive it i cant rly get so many wheelies with my 9.6 v battery which i find it strange. is it the clutch that is worn out already?

    The stock slipper clutch pads need to be maintained ever so often, they develop a hardened glaze on them, a light sanding will take care of it. Sometimes the tensioning nut can back-off a little also.

    Excessive wheelies is more a sign that the clutch is adjusted too tight. If the clutch is worn out or glazed it will slip more and the truck wont want to wheelie at all.

    Welcome to the forum, Mr Sweden!
    As all the guys have told you above, you will have to ugrade the drive shafts sooner or later (if you like wheelies probably sooner )
    I'm not the most experienced one (have had my P4de since january -13), but as soon as the snow melted away I upgraded to the MIP X-Duty CVD's front and rear:
    http://miponline.com/store/mip11110.html
    http://miponline.com/store/mip11109.html

    Recently MIP has launched a lighter version (a little cheaper) which look almost like the Tekno's:
    http://miponline.com/store/mip13260.html
    http://miponline.com/store/mip13270.html

    The Tekno driveshafts are these:
    http://www.teknorc.com/shop/tkr6851x...4x4-front-6mm/
    http://www.teknorc.com/shop/tkr6852x...-4x4-rear-6mm/

    There are pro's and con's with both MIP and Tekno. The MIP's are heavy and rock solid, and you can upgrade to aluminium hub carriers and steering blocks later on. The MIP's concists of more parts, and you need to be careful when assembling them if you want to avoid problems later on (loosing set screws and pins). The Tekno's limits you to Tekno's own hub carriers and steering blocks (plastic), but you get bigger and more solid bearings. They are easier to assemble and virtually maintenance free.

    As for the slipper clutch issue, take a look at this post:
    http://traxxas.com/forums/showthread...slipper-clutch...
    You'll need Traxxas parts #5351 and #5352R (but use the spring from the stock slipper assembly).
    And while you are at it, get Traxxas part #6893X alu bearing adapter. It's a cheap and necessary upgrade.

    Somewhere around a quarter to half a turn back from fully tight works for most, but in the end it depends on your driving style...... personal preference.

    Another thing to consider is the warranty, MIP and Tekno have one. Traxxas considers them a wear part, no after purchase support. Not to take anything away from Traxxas axles, because they are a good piece. Only thing is the pin is only held in place by the rubber boot, if the boot tears you might loose the pin.

    Some have problems with the MIP grub screws backing out at the diff out. This once happened to me and i figured out that I haven't let the blue loctite dry long enough.

    Next time i waited 24h and no issued since then.

    Some people with that issue use one pin that goes throug the hole instead of 2 grub screws that just sit on the flat spot of the diff out.

    Hello, Mr Sweden

    If you want the MIP X-Duty CVD's, these are the ones:
    http://miponline.com/store/mip11109.html
    http://miponline.com/store/mip11110.html

    Stay away from kit #13115. The dogbones are made of aluminium and are restricted to 2S. They are not made for hard bashing - more for track racing. However, MIP has just launched a version with steel dogbones with no restrictions to only 2S:
    http://miponline.com/store/mip13260.html
    http://miponline.com/store/mip13270.html
    Unfortunately, they are not really "on the market" yet (on back order at MIP). But they look really good (much like Tekno's).

    Wheelies are fun, the Traxxas driveshafts are too weak for wheelies though, don't get the same plastic replacements, MIP or Tekno is the way to go! Then you can do all the wheelies you want without any big problems!
