Replacing woofer on an active sub

So I have recently dug out an active 8" sub from my shit heap and have noticed that the speaker diaphragm has been deformed. I am wondering how likely it would be for me to completely screw up an install of a replacement speaker (basket and all)? is there any silk touch to it or is it a pretty standard procedure?

It is very easy. Look up YouTube videos on how to choose the replacement driver.
