Jarring of drive wheel

Hi guys,
 
Needing some help with diagnosing an issue with the SW20, this is with a E153 gearbox and standard LSD that it comes with. other work done was to replace the CV's with the ATS racing cages.
 
When it was running, we noticed some abnormal noises and you could feel what felt like a bit of jarring when going around left corners with the clutch engaged in both forward and reverse directions... this was happening at less than 10kph and driving speeds. straight line and to the right made no apparent issues.
 
On the hoist everything was turning freely when we turned the wheels together or singularly. Taking the longer of the 2 drive axles off we saw the bearing that is midway along it had a piece missing and a nice spider crack in it... replaced the bearing and put back together... refilled gearbox fluids, also checked for full range of motion in the RHS CV and it had full motion when rotating and slid in/out freely.
 
The problem is prevailing at parking speeds but not as severe but seems to be gone when we went around the block.
I'm just wondering what else to check when it goes back on the hoist?
 
 
I suspect the issue has to be in the Diff, or the CV's, but already checked one of them and 3 of us believe it looks completely normal. I contacted ATS and they informed me it should behave like the standard CV's would... I double checked the correct amount of fluid is in there as I remember having a similar issue when insufficient gearbox oil was put in, but is there anything else that should be checked or might explain the issue? Could suspension setup create this problem as I've also put roll centre adjusters on the rears too?
