knocking from rear suspension

Hi All, 03 plate td5 discovery still on air and ace. Ive replaced the rear hockey stick bushes with polybushes over the weekend now have a knocking when turning and over the bumps. All bolts are tight ,first time using polybushes can't see anything wrong under it. Any ideas ?? Watts Linkage ? or could it be the poly bushes moving ? Thanks All.
