don't bother to put the strut back on the rear knuckle. you will have to pull the shaft to replace the boot, and the strut out will help.
You will need transmission fluid (maybe), and a new boot kit (or two). It's not hard.
Your Chilton / Haynes manual will have the steps to pull the shaft and to replace the boot / shaft back in the car..
Wanted to add:
I usually put the top bolt in first, then push/pull on the strut until I can get the lower bolt in.
You can do a boot replacement three ways,
1 pull entire shaft, swap out needed boot. need one boot, transmission fluid, and a big torque wrench
2 pull the transmission tripot end (leaving the transmission part still in the tranmission), leaving the CVD (outer) end in the knuckle. remove the spider bearing from the loose end, then replace the outer boot, and slide the inner boot on the shaft. Install the spider bearing back on the tripot end and re-insert it back into the tripot (still hanging out of the transmission). no transmission fluid or big torque wrench needed, but two boots needed.
3 pull the CVD end (outer near knuckle) out and leave the transmission end in. need one boot, but need a big torque wrench.
