I recently asked about the procedure for replacing the half-shafts on my S60 T5, but no one replied, except to say that if I did the job, I should post it for future use by others.
Here you go:
----------------------------------------------------------------------------------

Piece of cake, really.

1) With weight on wheels, Loosen lug bolts 1/4 turn, remove wheel center cap, and loosen axle retaining bolt.
2) Jack vehicle under center front cross member, and place a jackstand under each side.
3) Remove wheel/tire assembly.
4) Remove Axle retaining bolt.
5) Compress brake caliper piston 1/8" and remove brake caliper assembly and suspend from spring w/ a stiff wire.
6) Remove rotor retaining bolt and remove rotor, and brake backing plate.
7) Remove ABS sensor from steering knuckle and secure out-of-the-way.
8) Using a socket and dead-blow hammer, tap axle inward as far as possible.
9) Mark outline of the upper bolt on the aluminum knuckle (it is slightly elongated for camber adjustment), then remove both bolts retaining strut to steering knuckle, and pull knuckle outward off strut.
10) Pull steering knuckle as far outward as possible while pushing outer axle inward out of hub bearing. There is plenty of room for the axle splines to clear the knuckle by maneuvering the knuckle at an angle.
11a) RT axle: Remove two bolts securing the axle bearing retaining clamp, then pull axle free of the transaxle, being careful not to damage transaxle seal.
11b) LT axle: Using pry bar, apply pressure to "pop" the axle free of the transaxle. There is an internal "C" clip that retains it in the transaxle. Then withdraw axle from the transaxle, being careful not to damage seal.

Note: There is a dust seal between the outer CV joint and the unit hub bearing that should be removed and inspected prior to re-use. Note orientation on removal so it can be correctly re-installed.

Replacement is the reverse of removal. Apply grease to axle splines and left axle retaining clip prior to installation.

Note: If you wish to replace unit hub bearings at the same time (which for $90 per side from FCP, I recommend if you have 100k+ miles on the bearing), remove the 4 bolts retaining each hub to the steering knuckle (preferably with an impact wrench), and install new hub bearings prior to re-assembly of axles.

Plan on about one hour per side for axles, plus an additional 15 minutes if you replace the hub bearings at the same time.

Hope that helps!
