2005 xc70-rear struts and coil springs

I don't understand how to orient the spring seats into the strut anchorage. It seems to fit inside fine in every position as you rotate it all the way around. Hard for me to believe it doesn't matter though. There are no obvious notches or anything to indicate where you rotate it to.

Any advice on this?

what year? When I did the struts on my 850, the spring ends align the strut to the spring seat and the bolts align the mount. On my Gen 1 S40, there's a hole in the strut and spring seat/mount that aligns at 0 degrees or 20 degrees depending on suspension set up.

 

Sorry 2005 xc70, edited above.

 

Thanks. I don't think the 850 is the same then. Yes the spring fits into the spring seat and the strut fits into the coil spring into one and only one position. But then the bottom of the strut piston rotates freely into any orientation to line up with the control arm bolt. Which leaves the spring seat free to rotate around inside the anchorage with no apparent home position.

What am I missing?

you are supposed to make a witness mark with chalk before disassembly to facilitate installation
