Grease or Fluid in the Diffs?

[cs49230]

Just wondering what owners with history on these trucks are doing for the diff lube? Any special reasons for choices? Personally I prefer fluid like I've done on the 1/10 to 1/8th scale trucks. Any balance (oil weight, frnt, bck) recommendations?


I do open field bashing, small air, high speed sweeps. Everything seems fine but I want to check the diff shims and it would be a good time to go oil if it isn't already.


thanks in advance

I have my Sons apart on his Chimera and the diffs are filled with ultra thick silicone fluid. Im putting 7000 in front and 5000 in the rear diffs

Get rid of the goop thats in there stock. It breaks down quickly.

I use fluid 7k front and 5k rear too. If your on more of a prepared track, something a little lighter would be fine. I currently use ofna brand but haven't found much difference between this, losi or traxxes fluids.

On these larger diffs, iv seen grease used but placing the weight becomes harder but I don't think there is any downside. Just make sure its a quality lube. Marine grease is good stuff. I use that stuff on the ring and pinion.
