Tom,

In March or April of this year I posted a fair amount of detail and a PDF file with all parts numbers, prices and torque values for the front suspension rebuild I did on my 1999 W210 with about 170k miles. Might be some helpful info there for you including how to access the front control arm bolts & nuts.

Let me know if you can't find the post and I'll do some digging around.
Hope this helps.
Ken
