Some teeth look worse than others. I'd take it out and check the pinion gear and its bearings.

thank you all for the reply. I think I’m on week 3 or 4 and probably pack 20?

I should replace the bearings. I assume I can just slip it out - no need to take off more parts of the car?

You can just slide the diff out, unscrew the set screw on the input cup and take the pinion out. I think. Benefits of a race truggy derived design :)

I think the diff will be fine but that was a ton of dirt in there. Make sure the 4 screws that hold it to the chassis are tight. They will slowly back out over time. And if any of them won't tighten because it's stripped, replace the gearbox.

Edit: or do what some of these guys do with stripped screws in plastic and use a piece of zip tie, a longer screw or CA glue.
