Normally nwhen someone says "I have a clunk" and especially if they then say "and oh, my brakes pulsate a bit", it it most certainly the radius rod bushings as you call them. If they are worn, they will make the front end clunk and they will not only create pulses when you brake, they will actually warp your discs for you. In fact, problems with the control arm are so intimatley linked to the symptoms you describe that I am going to suggest the following, somewhat drastic action: get brand new or almost new from a scrapped car control arms, then get new upper and lower control arm bushings and then get poly radius rod bushings from IPD. It may sound a bit drastic but if everything else is replaced... Other than that, I can only think of replacing the few bits left to replace, i.e. spring and strut rod bushing and bearing.

Perhaps even crazier but have you checked that nothing else is lose, like the engine, transmission, fuel pump...
