[A8] 98 A8 odd sensation in sharp left turn when cold

[Martin Karo]

Recently, I've noticed that when the car is cold, and I make a sharp left
turn at slow speed, the outside wheel (right front) feels like it's rolling
over sticks or marbles, and there's a low rumble (again, consistent with
rolling over sticks).  After driving a while, the symptom seems to go away.
It isn't making any noise in regular driving.  I recently replaced all the
suspension components, so I can't attribute it to ball joints or the like.
Any diagnoses?  I'm thinking right front universal joint, but I really don't
know, nor do I know a way to test it.  On visual inspection, everything
looks fine.
