My 2004 owner's manual says, "...wait for at least 5 minutes after the engine has been switched off."

Neither of those numbers on the old struts.
They may use different numbers when supplying direct to Volvo.
The exact label was:

VOLVO

SACHS
82 4904 000 085
Made in Germany

I noted the blue p/n sticker on my old struts, it was 30645640.
I measured the distance from wheel center to bottom of trim, it's about 45 cm, or 17 3/4 in., same as someone else listed.
In the...

Are you sure you have the correct struts?
The dealer actually installed the wrong struts in mine. Then, after they couldn't align it properly, discovered the error, and had to order the correct p/n...

I must correct my earlier post where I said my spring paint marking was yellow.
Upon a closer look, the marking is yellow plus blue.
I can see how you might call the color orange...it's not a...

I just went through spring, spring seat, and strut replacement for my 2004 with 156K mi., due to a broken front spring.

Great, clear pictures like that are required in order to make sound judgements....

How did you discover the problem...mechanic, or dealer? Were there some other unneeded "fixes" performed on the path to discovery?

Barinthus -
Did you buy the XC new or used? If used, maybe it took some rough roads in the first years.
I can't think of any other failure with the potential to be as catastrophic (maybe wheel...
