Hey everyone,

I'm new to RC and bought the Traxxas 4x4 VXL Brushless 3 months ago. It's been running great, I mostly take it to the beach and have my dog chase it around.

A few weeks ago it stopped working, so I took it apart and noticed the gear had pretty much been shredded and it had no tread left, so the motor spur wasn't catching. I ordered a replacement gear and put it all back together. I also used a compressed air can to blow out a bunch of debris, sand and dirt. The spur catches now but it's making a terrible squeaking noise, and I'm not sure what it is.

Here's a video (note the dog squeaking in the background is a separate issue )


Any thoughts on what to look for next? It looks like the car could maybe run fine with how everything is working, but the sound is worrying.

Thanks for any help!
