I'm glad you posed the question. I have a 2001 CLK too and I have what seems like excessive play in both front wheels, expecially the wheel on the passenger side. I don't have any symtoms of pulling or vibration, but when I had mine on a lift last month, the wheel movement both left and right was more than I had expected. I'm not familar with the tie rod assemble on the clk and didn't know it the variances or what is considered normal.
