Need help diagnosing frustrating steering/suspension issue

If you are going to replace those items, you may as well replace the coffin (lower control) arms as well, as those can contribute to the feeling you are describing.

Did you say you did or did not replace the control arms?
That's what got rid of the thumping noise over bumps for me.....

I have not replaced the control arms - the guy I brought it to said the rear trailing arms were shot but didn't mention anything about the fronts. The noise doesn't really happen over bumps - it's really just driving straight at any speed over 30 and its like a rapid jitter / vibration more than a clunk I guess.

There's a huge difference between the Porsche part ($400 each!!) and OEM from URO / OCAP / Beck Arnley (about $90 each). Do you have any experience with the OEM parts?
