I don't think it's anything to do with the engine used. My first S60 D5 MY 2002, and my current V70 D5 MY 2003 both had/has aluminium wishbones. From what I can ascertain they changed over in 2007 and they aren't interchangeable. Although registered in June 2007 my S60 is classed as MY2008. Maybe that's the difference. Either way anybody replacing them needs to know which type they are. One disadvantage of the steel ones is the rubber steering limiters are riveted to the control arm so it isn't such an easy job to swap them side to side to even out the wear. The steel ones do seem to last longer, however, as mine are now at 132K miles with no obvious evidence of serious deterioration.
I think this has moved too far off the original query by GaryS40 to continue in this thread.
