Cayenne 2004 Turbo Air Suspension Boots

[Yagura6120]

I got Rear Air Suspension Boot crack and would like to replace it by new one by myself.
I research Internet and find U-tube to explain how to remove Air Suspension for replace.
But I am now thinking any other easy way for Boot replacement without completely remove the Air suspension assembly.
But I am not sure if it can be done or not.
I am assuming that lifting up Cayenne and remove wheel then just remove M12 Hex Bolt and protection Cap to disconnect between Shock Absorber bottom and Lower Arm.
Then just want to replace the Boot from bottom.
Does anybody has experience about it? I guess may be not able to do.
Thanks,
