    Gear problems... i have no idea.

    Whenever i run my slash down the street, it is fine up to about 20 mph but once i go higher than that, then the car makes this really weird noise that sounds similar to a fork scraping on a pot. It doesn't happen constantly, just every 5 seconds or so it will do it for just half a second or so. I think it might have something to do with the rear diff because i had to take it apart and clean because sand got in there, and just sprayed wd-40 in afterwards so that might be it. That was probably a stupid idea. If that's it, does anyone know what i should put in there instead?

    I put 10k in rear and 15k in front. Its all about power transfer. If its leaking you may have overfilled it and pushed out or cut the o-ring seal on the housing. Or you may not have the 4 bolts tight enough.

    What was the last thing you did before the noise started?

    (slip adjustment, gear swap, etc.)
