Go there and check the ultralite diff instal instructions.

Hello,
Thank you for your answer. In fact, I did the setting of the diffs as explained in UE manuals. And it is ok.
But, when I put the full differential with its housing on the chassis (between the bulkheads), this is the full piece (meaning the housing, (diff box ?) itself) which is moving between the bulkhead... around 1 millimeter.
So either i did sthg wrong... or, adjustments mixing Gorillamaxx, FLM and UE are not perfect...
