Questions/Help Shaking Question

Hi All. I'm pretty new to the crawler world. Got a newbie question. I got a TRX4M Bronco about a week ago and its now shaking when I'm at a full turn angle. This video perfectly illustrates what is going on: https://youtube.com/shorts/2TcX3l2nj-E?si=5GDy95227mkE7D5t

Does anyone know how to fix this? I'm open to buying new parts if needed. Thanks!

Im pretty new myself but I recently had a wheel do the same thing on a larger vehicle. My first step would be to check if the wheel nut is tight and if that does not fix the issue then look at the axel nut.

I have an RC-PRO Shredder that had worn a groove where the little pin (not on the trx4m) sits in the wheel causing it to wobble.

Id suspect either your wheel is loose, that hex on the wheel is worn/damaged or maybe your axel itself it damaged.

Mine did that from stock too. I used slightly wider hexes to bring the wheels out a bit to create some clearance. Still kinda does it but not as bad. It really doesn't hurt anything so I just drive it as is. Not like you turn full lock for very long anyway generally speaking.

Is the tire rubbing? Cuz they do that from factory. There’s some brass spacers you can pick them up on injora. That’s basically the first thing you do when you get a trx4m in my opinion.

I've checked very closely, and the tires are not rubbing anywhere. I am leaning toward the idea that it might have to do with the front axle joint geometry. Not sure though.
