clutch removal

Hi all,



I hoping for a little advise please, my mums clio 1.2 02 plate has started to slip on the clutch. going to replace over the weekend, could i have some advise on the following please.

1. as its cable does the gear box oil need to be drained.


2. does both drive shafts need removing or just the passenger side.


3. and on average how long does it take, not done a clio before.


4. also i have seen mixed answers on sub frame, does it need to come out or can it be done with leaving it alone.

Thanks in advance
