Default Pre 2011 XRAY diff bevel and satellite gear lifespan?

Mine started making some noise the other day which led me to wonder, how long are other guys getting out of their satellite gears? (or how many gallons perhaps)

How often are you pre 2011 XB808 owners changing diff fluids?

Thanks

I usually change them after 2 races. Maybe after 1 race sometimes, not that I need to. I just like to

The gears inside the diff would normally outlast the chassis and rest of the car.

One big race a a couple of clubs races then you should probably change fluid.

Well that's interesting. Since this is my first XRAY maybe you can answer this:

With the diffs apart and dry and with the four satellite gears in place inside the case, if I place slight pressure on the top of the pins while spinning the coupling, should there be any noise? I'm getting a clicking sound both wet and dry when I do this and was told there should be no noise at all.

Hopefully that makes sense.

And to be more specific, I'm talking about the smaller side gears, or spyder gears, as some would call them.

That's entirely normal, the clicking sound is caused by the gears engaging eash other. However just make sure you have the 964030 3.5x12x0.2 shim behind the satellite gear as mentioned in the manual page 7 & 9.

Damn. Hope I didn't just order a complete set of gears for nothing then.
