Looked this up once for someone and posted it over on Swedespeed. I'll repost it here:

Vadis says this:
Remove wheels and then:
detach bracket for brake hose and ABS cable, let bracket hang loose, detach link from anti-roll bar, then detach link/ball joint from the stub axle (both sides). Install protective sleeve #999 5562-7 (protection-balljoint pinion).

Next (left side- driver's side) detach the shaft from the tranmission by using disconnect tool 999 5462-0 (Jimmy tool) used between the transmission and the inside of the drive shaft joint. Fold out spring strut and remove drive shaft from transmission. Use a crowbar to remove the seal ring.

Installation: Apply a small amount of grease to sealing lip. Use drift (punch) #999 5541 and handle 999 1801-3 (standard shaft) (Vadis specifically states to NOT use the old drift #9995478). Place the side of the drift marked AW against the seal ring. and carefully tap in the seal ring until the drift is up against the transmission housing.

On right side (passenger side), replace the bearing cap and torque to 19ft.lbs.

For Left (driver's side) ensure that the anti-lock braking system (ABS) sensor pulse wheel is free from dirt and press the drive shaft in firmly so that it locks on to the differential gear. Ensure the drive shaft lock ring sits in its locking groove. Check by pulling carefully on the drive shaft CV housing.

Last of all make sure that both seal rings in the transmission and the boot on the drive shaft are not damaged. Reinstall the Link/ball joint stub axle. Remove sleeve 999 5562 (ball joint pinion protector you put on earlier, if you used it) from the ball joint. Use new nuts and screws. Torque to 30ft. lbs. Reinstall the link to the anti-roll bar..also use a new nut, torqued to 37ft.lbs. Reinstall hose bracket and reinstall the wheels on both sides. That's it!

I think you can take it from here. Lube the hub center dowel for the rim with rust inhibitor, tighten studs lightly and torque diagonally, etc. Check your transmission fluid level and you're pretty much done....

You may need the specific tools mentioned here but the diagrams in Vadis looked as if they were pretty common tools I see at Autozone...but don't know. The Jimmy tool looks sort of like a large crowbar except the opening is not V shaped but rather "U" shaped.

Good luck and yes, we'd like to see pics of the process if possible. Unfortunately I haven't seen a write-up with pictures.
