Thanks for the list rumb, I will check these items as you suggest. The steering damper has been changed. This all started with a broken support strut that sits next to the steering damper, so I replaced it along with the support strut. The only reason I mentioned brake disks is that a coworker of mine had a similar problem and it was a disk. I will only replace them as a last resort. They were replaced not that long ago by the previous owner.
Thanks again.
