I have had a clunking on rough roads for some time in the Focus. "bcardinal", our resident Ford parts man advised me to replace the front link arms which I did this morning. I have been waiting for my melanoma surgery to my upper right arm to heal a bit more before I tackled any repair work so I finally got around to it this morning. Good news! That was the problem. The new ones have grease fittings on both ends so hopefully I won't need to do this again.
