    Revo is Ticking, what's up?

    I just changed out the spur gear. I'm pretty sure I got the mesh right. The truck is running fast, but's it's making a sound like plastic gear grinding in opposition to plastic gear. Can you guys offer me some insight?

    OK. I'll pull off the shield on the bottom and peep it. Thanks!

    Also make sure the screw pins didn't back out

    I checked. There was a little rock but not enough to matter. Though the driveshaft looks a tad bit like it was on a lathe. Things are still ticking though.

    Thanks for the advice. I checked. All's good.

    Could the rear diff be the problem?

    the rear diff would only click under acceleration. If it clicks any other time, its not the rear diff. Well, unless you have a tooth broken completely off.... But then you should be able to feel it slowly turning the wheels by hand...

    The rear diff could definitely be the problem. The ring gears occasionally shed teeth.

    I think that's when it ticks, when accelerating. Sooner or later I'll get around to pulling the rear end apart.

    Pulled the rear diff and a gear was stripped pretty well. While I was fixing it, I also upgraded the driveshafts and axles to the steel daddies.

    My son beats the h311 out of this Revo. He gooses it constantly, runs it full speed into puddles, and generally does what he wants. Nothing's gonna change HOW he drives it. (My son has autism) I just have to keep it operational. :-)

    Since I was now familiar with the rear diff area I decided to upgrade the rear bulkhead to Hot Racing's aluminum version. I also removed the front driveshaft just for troubleshooting reasons, to help me figure out if the clicking was gone. I can confirm the clicking is no more, but now the Revo is rear-wheel drive only. My son doesn't seem to mind because it's still smokin' fast. I'll soon pull apart the front bulkhead and drop the driveshaft back into place thus making it a 4x4 again.
