Steering rack removal procedure

Hi, I recently purchased a lightly damaged 2012 i20 Active and as part of the repairs have to replace the steering rack. Well I didn't have to, but it was more economic to buy a complete used rack assembly than buying just one new outer arm from the dealer.

Anyway, the job looks straightforward enough, but before tackling it I'd be interested to know if anyone knows the factory removal/replacement procedure that they'd be willing to share? Might just make the whole thing a bit less trouble!

Any help/suggestions much appreciated.

Cheers

Drew
