Just a note: On My 98 S70 once the link is off the sway bar moves
up (its like a spring) and no longer will align with the end of the link.
I placed a long wrench (piece of metal pipe would work) under the A-arm
with the top over the sway bar. Push down to position the sway bar
back so it aligns with the link end (so you can bolt it back on).

Above assumes you connct the sway bar end last. Would have same issue
if you replace the bolts on the strut end last and using a pry bar
should still work to line it all up.

Like Sin said, easy job, harder to explain then actually perform.

It takes a whole 10 minutes for me. I simply jack up the front of the car, and support on jack stands (it is most easily done without weight on the front wheels due to the fact that it links the travelling struts to the chassis through a metal bar that flexes). Remove the wheel on the side that the link is to be replaced (btw, I highly recommend changing out both if you haven't changed the other one recently).

Depending on the generation linkage you have (there are 3 redesigns) the nut retaining both ends of the link, may be removed simply by unscrewing it, or, you may require a torx bit to lock the bolt the nut is screwed to, in place, or use an open ended wrench to catch the cut outs on the metal assembly hidden behind the rubber boot, while you unscrew the nut.

Trust me, this sounds a lot more complicated then it actually is. When you have it in front of you, it becomes blatantly obvious how to remove it.

BTW, this is a common failure, and I have learned to keep on in my garage at all times. And lastly, the latest redesign is superior by far, as well as significantly cheaper.
