Harb,
My 2000 E320 with 41,538 exact miles also has the steering wheel squeek. I also have to drive it for about half an hour or more until the squeeking starts. I took it to my local dealer, they said it was a dry boot and just needed some lubrication. After a couple of days the squeek is back again. I haven't tried to flush out the power steering fluid, have you tried it already? I just hope this is not a rack and pinion problem, I am not looking forward to paying for that. [V]
