I poly bushed both bushes on my wife's xc90 earlier in the winter. I can't say I noticed any negative effects. They replaced Meyle bushes that were beginning to deteriorate.

I poly bushed my series 1 S80 a few years ago which has similar wishbone set up to the xc90 and again no negative effects. The steering feel and turn in was much sharper and less wooly on the S80.
