    I would check your diff bearings and also look to see that your diff housing where they sit isn't worn or out of tolerance. Past that it would have be in the actual diff that things are worn. Follow the out put shaft out of the diff and you'll see where you could get any slop. Diff bearings are the first place I'd look.

    If you're not too concerned about it you can just run it. Worse that can happen is you blow out your diff. It is alot of work to replace that housing. Might as well run it , then replace everything while you have it torn down.

    If I purchased a metal housing would that remove the issue? Also is this a problem you only get with mip shafts?

    I don't think anybody makes an Alloy diff housing for the slash/stampede. I dont think it's that big of a deal. The tolerance isn't super tight from the factory. I wouldn't worry about it. When it's time to rebuild your diffs, upgrade them to xo-1 spec, see if shimming your outputs would help and carry on. I've had MIPs for so long I don't remember. My sons stampede has the stock axles on it right now, I'll go take a look in a bit once the kiddos are in bed and see what kind of slop his has. I was wrong gpm racing makes one. 44$, ouch.

    I checked my son's too. It is pretty sloppy. We might be overthinking it.

    The XO-1 differential is more robust. It has a metal I bar in it to help prevent movement. In the stock differential there is only a pin. So if you aren't using really thick differential fluid expect some movement.

    Yeah I put some thick grease in and it didnít move at all but after a pack it was moving again.

    I run 50K in my stampede diffs. They wobble. I just make sure the grub screws on the MIP stay tight and bash it till it breaks. Next time I rebuild, I may try just the HD cups with the steel inserts holding the cross pin. It won't really help the output shaft wear though.
    Expert rigging at it's best!

    Sometimes it is just a rabbit hole of what we think is wrong and what actually isn't wrong. Wait till breakage before fixing.
