Halfshaft indexed?

I am chasing a shudder in the rear end of my Cobra replica that uses TurboCoupe IRS.

The shudder comes from the backend and shows up mainly when the axles articulate. I first thougth it was tire rub but wasn't getting any marks in the wheel wells. The more I drive it, I wonder if maybe it isn't the half shafts.

Do the ends or internal rollers/carriers need to be indexed or aligned a specific way?

When I am driving down the highway normally - no issues. When I get into some body roll, aggressive cornering or suspension loading/unloading, it shows up.

The differential is a 3.55 TrakLoc and I don't get any chatter as it corners. I am using Lucas 85W140 lube that supposedly doesn't need any additional friction modifier in it.

Open to any ideas or suggestions. Is this something that is common to the rear ends design?

Thanks for any help

No, the half-shafts do not need to be indexed. From what you are describing, I would suspect maybe a bad rear wheel bearing.
