I replaced my right tie rod assembly yesterday. I wasn't confident about my skill with the hammer method (as described so well by Larry Bible) so I bought the following tool:

This is a fine quality, heavy duty tool and it worked like magic on the tie rod end of my W124 (1988 300e).

I have seen this tool advertised on-line for between $54 and $74. Right now http://www.mytoolchest.com has it on sale for $27.27

Highly recommended!! (I have no connection to mytoolchest.com)
