urS4 front end clunk

[cody at 5000tq.com]

My boss' newly aquired urS4 is driving he and I batty with a front end  
clunk. It's very intermittent, usually happening when the steering is  
near or on the lock (either direction) but not easily reproducable. It  
sounds like the right side.

I have just replaced both the control arm and tie rod end on the  
passenger side and the clunk did not change. It's a loud clunk, and  
also can be felt in the floor board.

I used a multi-input chassic listening device with an input on the  
upper strut nut, the subframe near the control arm bushing, the tie  
rod and the end of the sway bar (the threaded portion). The clunk was  
audible only through the input clipped to the sub frame near the  
control arm bushing.

I can't get anything to move out of the ordinary using a pry bar. The  
subframe only moves with the bushings, it doesn't seem to move vs. the  
chassis with the pry bar. I marked the sub frame with the intention of  
seeing if it moves vs the body while driving, but haven't been able to  
check on that quite yet.

My internet at home is down for a few days, so don't expect any  
replies with more info until lunchtime tomorrow :-(.

Any ideas / BTDT?
