This is just quick guide and to point out that these diffs are a little more complex to fit correctly in their housings..!!
So this is a question for everyone that has taken their diffs apart to service them or are about to, what I'd like to know is do your diffs have the large shims on the outside of the bearing on the right hand side like mine, you can see the large shims between the outdrive cup and the bearing.??
With the new style of flared outdrive cup you can't just slide the shims on after assembly which is quite annoying to be honest, so now to adjust the diff lash correctly you have to build the diff completely, fit it and check for play, then disassemble the diff add or remove the shims as needed then fit back in the car
Here you can see all the parts from my front diff all laid out, top left are the two large shims.
In this exploded diagram there are no large shims pictured, but so far everyone of mine has had these shims..!!
The purpose of these missing shims is to remove any lateral play in the diff whilst it's inside the housing, and also to push the ring gear into the pinion so as to remove any play in the gear mesh.
It seems a bit weird to me that in all the Corally manuals I've seen so far these large shims are just not shown, as every other car I own regardless of brand they have these shims fitted and shown in the manuals..
This particular manual below is a Radix 6s.
My overall opinion of these diffs is they have a very good fit and finish, they're also beefier than stock Arrma diffs in my opinion.
I'd suggest taking your time to build them as they feel very nice when built correctly, shim the outside well so as to remove any play you may have in the diff housing.
Once I rebuilt mine they felt very smooth with no binding whatsoever, I then used the large shims that were fitted from the factory and my diffs are nice and tight in the housings with no lateral play..!!
Good luck
