If you guys come up with any end results please keep them coming as I am having the same issue.
99 323 has 175k. I recently replaced my tie rods, front control arms and FCAB. Got an Alignment, tires balanced and rotated. Tires are only 6 months old and there is no irregular wear pattern. Front bearings were replaced about 40k ago and I have never replaced struts.
The car ran smooth before I pull the wrench out and started replacing everything.
I too am experiencing the vibration above 60mph. After alignment it still veered to right so I took it back. Right after balancing the front left had thrown a weight so I thought that would be my issue but I had them rebalanced and the steering wheel vibration is still there, although it does seem to disappear at times.
