Hi all. Im starting to build the Axial SCX10, but I just have two questions so far

1) Tight Diff's.
Im certain the instructions where followed correctly, and enough grease was applied to the gears, but the when turning the univeral joints to turn the front and rear diff's the gears are "clicking" together. I've loosened off the screws on the diff covers and the rotation gets smoother and quieter, but any more and the diff covers get quite loose.

Is this normal? Perhaps the gears will mesh into each other with normal usage ?
I have not yet connected the universal joints to the motor mount as Im only up to building the chassis yet (and haven't yet bought my motor).

2) The shocks seem really stiff.
I've refilled and certain I've removed all air bubbles. I didn't fill the oil to the top as its gets way too stiff. I've watched YouTube videos on how to build these with other RC cars and Im following the same process but my shocks still feel way too stiff.....
Maybe I've gotta see how they work once they are all connected to wheels and the chassis ??

thanks for any insights ...

Not sure about your shock issues but the issue your having with the diff can be a common one if you haven't seated the bearing properly in the diff housing take a look at this post #39 Live Axial AX-10 build

you actually want to fill the shocks all the way to the top.
from there you have to bleed them properly.
basically,
-fill to the top w/ oil
-push and pull the shock shaft up and down to make sure there is no pockets of air stuck under the piston
-allow all the air bubbles to escape (may take a while depending on what weight oil you're using
-add additional oil if needed. shock body should be full
-w/ the shaft in its fully extended position, hand tighten the shock cap all the way
-loosen the cap about a quarter turn
-push the piston up as slooooooowly as possible to let the excess oil bleed out. when i say sloooooooow i mean exactly that, full extension to full compression in no less then 45 seconds to a minuite
-after bleeding hand tighten the shock cap all the way.
