I have no problem admitting I am no diff guru and have never been able to build the "perfect" diff, but I have been building them since gold pan RC10's were around so I do understand how they work and how they go together. I am on diff build number five now (counting the initial build) and it does nothing but slip. Even fully locked (or what should be fully locked) I get immediate diff bark as soon as I pull the trigger. The shim between the bearings is in place, rings sanded, thrust washer races are facing the balls, black grease on thrust assembly and diff lube on diff assembly. The only thing that strikes me as odd is that the thrust bearing is only caged on one side, is this normal?

EDIT: short vid of slippage, last 2 trigger pulls (very end of video) you can clearly hear the diff barking, this is 1/4 turn from fully locked.
