Steering: Hub assembly???

There is a difference in spline size only in the differential end for auto/manual transmission.
There's no difference in drivehsafts for engine type besides N/A petrols that came with a lighter driveshafts but have same spline sizes per transmission.

And the front spindles are same for all S60, S80, V70 and XC70 P2 cars.

Thanks for the correction. I got the wrong inf from the web - had to replace mine recently

Actually, I was wrong about all the P2 cars sharing the same spindle.
The spindles differ since the new design ball joint has a bigger diameter splined insert.
However no distinction between models.

the steering arm will have some play in it as standard is this what he is referring to?

Volvo changed from aluminium suspension arms in early models to steel, certainly by 2007, and with it the size of the ball joint taper. It's possible you've been sent a hub assembly from a later car. If your original lower ball joint is OK you may be able to remove the joint from the replacement hub and reuse the old. There are various youtube videos showing how to remove the ball joint, but be careful when pressing the 'new' one in; you need to press on the flat plate and not the ball joint itself. I've used a 2" bsp pipe fitting large enough to fit over the rubber boot without damaging it and long enough to come past the end of the of the ball joint stem. Acces to a vice helps too. Check that the splines for the driveshaft are the same as your original as well, first.

I have a mid year 2007 and it's still aluminium

My S60 D5 first registered 06 2007 has steel wishbones!

I would have thought XC90 and diesels would have steel due to extra weight tbh

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.
