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

[Rich, Jack]

That was my first thought also.  I don't know that I've ever heard of one going  bad with a good boot packed with grease.  You would notice that everything didn't look fine if grease were spattered everywhere.  The good news is that an entire new axle with new boots and joints is available at raxles.com for around $175.  This includes the tools and a new wheel nut.  This is a very easy job to do yourself, except for removing the bolt that holds the upper control arms in place.  This was easily over half the time spent on the passenger side of my car, and if you discover it completely frozen, then PLEASE LET ME KNOW HTF YOU GOT IT OFF!  Check this bolt before proceeding further with this otherwise straightforward job.  If you can move it, then you can eventually get it out.

I assume you've checked for sticks or marbles (maybe acorns?) in your driveway.

Martin,

Sounds like a classic case of failing CV joint or split boot with lack of grease in joint. The joint is most susceptible to complete failure on sharp turns, so I'd take it easy until you get the diagnosis.

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.
