KM EVO Baja rear end wobble. Help!

[FastFisch]

Just wondering if anyone had any thoughts on what may be causing the rear end wobble and where I should start to look for the problem.

I added a video to YouTube. Check it out.
Thanks

I don't do electric but that sounds god awful like something wants to or has already broke. Swap wheels from one side to the other and see if the wobble follows, atleast it will indicate if the rim or tire is bad. Try the dumb stuff first but that extender looks to be rolling straight

Bent rim. Bent axle extender. Something in the driveline is binding bad!

Thanks for your replies. The wheels are aluminum and straight. I did take apart the hub carrier and rebuilt them already. Here is a another video I took with the wheels off. Is there supposed to be this much wiggle in the carriers? When I run it without wheels there is no wiggle but has like a thumping or chuging sound at slow speed. Doesn't sound good.

Start taking stuff apart and find out what’s binding

Well I took it apart a little bit. Everything is really smooth. Don't see any major bends on anything. I'm still wondering if there should be that much play in the the rear wheel carrier. The pins that go through the carrier and a-arm have a lot of slop to it. Is that normal?

Won’t be the carriers. Pull the boots back and look at the dog bones and cups. Post up a pic. What’s spur look like? Pic.
Your mesh is adjustable. Wonder if the mesh is too tight.

Mesh looks good. Here are some close up pics everything looks good, nothing looks broke. When I spin the gears it's all smooth.
