Front suspension "clunk" during turns (.wav file) - wheel bearing?

[ripp222]

I currently have a "clunk" comming from the front suspension on my 2004 X5 with 64,000 miles. The level of noise it makes is not consistent, but when it's loud you can feel it in the floor board through your feet.
Driving straight ahead, going over bumps, hitting potholes or using the brakes does NOT lead to the "clunk". Making turns is where you often hear multiple clunks. It is not consistent - sometimes zero, sometimes one, sometimes two clunks. Left or right turns. Occasionally when changing direction, forward to reverse (after the car has sat in the garage) I can get one clunk.

I'm leaning towards SIB 31 01 05, Front Wheel Bearing Noise for E53 X5's produced up to January 2005. Here's why...
Left outboard CV joint rubber gater replaced at 45k miles (CV joint looked good, despite torn boot)
Right outboard CV joint rubber gater replaced at 58k miles (CV joint was good, repair before complete boot failure)
Front tension arm bushings replaced at 61k miles (these bushings when worn make a different noise, repeatable upon breaking)

Using the search tool I found the following past threads...

I tried the test procedure in the SIB, but when I am stationary and make 3 revolutions with the steering wheel, the clunks occur about mid-way through the revolutions. I make the last revolution or so, then accelerate quickly in reverse, but no more clunks. The clunks I do hear are not as loud as those heard while driving, and there are more of them. To me, it does sound like metal sliding.

Your thoughts?

=============================
So here's a picture of the front suspension and front axle from TIS:




Here is a picture of the backside of the swivel bearing:


I assume there is a lip on the back side of the swivel bearing which limits the inward travel of the wheel bearing?
There is a snap ring on the front side to limit outward movement. So the play in between these two parts is what allows the wheel bearing outer cage to slide and make this clunk per the SIB?
