    Slash 4x4 platinum edition parts question

    Hi:

    I have two questions about Slash 4x4 platinum edition parts I hope you can help me.

    1. From this top view picture, you can see that my two rear wheels have a angles. Is this normal?

    2. My car hit the wall at high speed and broke the from part where I host the front bumper. Please see the picture here What is this part called? Can I replace it?

    Thanks,

    the broken part is the bulkhead, yes you can replace it

    yes, the rear has quite a bit of toe-in. if you run aluminum rear blocks, and put them on the opposite side, you can get rid of most of that excessive toe-in

    The plastic rear carries have 2.5° of toe-in, and swapping sides doesn't change anything. The aluminum carriers have 4° of toe-in when installed properly (left on left, right on right). If you swap them (left on right, right on left), then you end up with 1.5° of toe-in. If you've running more "straight" than "turns", leave them as they are (4°)...if you've running more "turns" than "straight", swap them.

    Alternately, you could replace the Traxxas carriers with STRC carriers, of which they offer 0° & 0.5°. If I understand correctly, the 0° will produce the same results as the Traxxas carriers, whole the 0.5° carriers will produce 4.5° (normal) & 2° (swapped). For my Rustler 4x4 (same parts in this area as the Slash & Stampede 4x4s), I purchased the 0.5°, and swapped them. Results on the track are quite nice.

    Correction: Swapping sides of the Traxxas aluminum rear carriers gives you 1° toe-in.

    Interesting, as elsewhere in this forum, there's indications of 1.5°.

    The Slash 4x4 rear has a built-in 2.5˚of toe-in. The aluminum rear carriers have 1.5˚ of toe.
    Installing as labeled: 2.5 + 1.5 = 4˚ of toe-in
    Installing reversed: 2.5 - 1.5 = 1˚ of toe-in

    See pages 23 & 24 of the Slash 4x4 Ultimate Owner's Manual:

    Coming from you, Squeegie, I trust it's accurate. I was only mentioning what others had posted (regarding 1.5°)...a trying to claim it was accurate.

    Just wanted to make sure you got the information from the source (owner's manual) and not just spread hearsay.

    If you want more adjustability, you can get the Tekno M6 rear driveshafts with rear carrier.

    With Tekno's rear carriers (the kit includes 2 sets), you can set it for 1˚, 2˚, 3˚, and 4˚.
    You can also adjust the roll center of your rig:

    From Tekno's manual:

    Their front driveshaft and carrier kit also allows for adjustment of bump steer:

    Have a great weekend!

    Forgive me if I'm mistaken. That looks like a broken front differential housing to me than a bulkhead. Maybe even an a arm that could use replacement.

    I agree, to me it looks like a diff housing also

    I can’t tell if anything else is broken due to the dark picture. But I agree the housing (pn6881) looks destroyed

    Thanks everyone for your help.

    1. For the rear angle, It was probably because I inserted a tube inside the shocks following the instruction here https://www.youtube.com/watch?time_c...&v=uytvBXu4xKE The goal is to make the car lower. I do not mind having the angle, but just want to make sure the angle will not make the car slower or damage the car.

    2. For the broken part, I have a clear http://artlystyles.com/tmp/Capture.JPG here. The damaged part was pointed by the red arrow. What's its name and how to replace it?

    Thanks,

    I believe that would be the differential housing.

    As others have said, front diff housing (p/n 6881):

    ah, ok. initial picture was goofy looking

    it is the diff housing in the front bulkhead (which may also need replacing if it is messed up, can't tell, depends on the arm)

    the whole front of the truck needs to come off. how come you don't have a bumper on it?

    Looks like a lot of work to replace it. Any youtube video about how to change it?

    I think you should be able to just pull it off. Keep your a arms off the way they are and pull on it. I can’t really tell if it actually needs replacing though. Maybe I just don’t see it but it doesn’t really look broken


    Edit: keep bumper off. And unscrew the two screws to the direct right and left of the diff housing

    Here is a picture about the broken part. http://www.artlystyles.com/tmp/IMG_8940.JPG. http://www.artlystyles.com/tmp/IMG_8941.JPG and http://www.artlystyles.com/tmp/IMG_8942.JPG The holes were used to host my front bumper from the top

    I also find some damage on the bottom of the car http://www.artlystyles.com/tmp/IMG_8943.JPG. The holes were used to hold my front bumper from the bottom.

    How can I replace them?

    I don’t think you need to replace the bottom holes. But you would have to buy a new bulkhead.

    You meant replacing the differential housing, correct?

    Bullhead looks good...a little 'messed up', but certainly still usable. The differential housing, on the other hand, NEEDS to be replaced. I would also suggest/recommend replacing the plastic bullhead tiebar, if the current one is plastic.

    It is the black plastic part that sits sideways/vertically on the front of your bulkhead.

    It is available is anodized aluminum:

    While you're at it, order two, and replace the rear one as well.
