Hmm, how difficult is a a RS Turbo?

Seriously, it just depends on the usual culprits; loosen hub nut, lift and support, wheel off, arb link off (optional, but I always do it), track rod end, bottom ball joint, hub nut off, loosen the 3 strut top mount nuts, puller if necessary to remove CV from hub. Cut old boot ties and boot off, lub up new boot, use tool or 2 thumbs (and a lot of swearing) to slide new boot into place. Apply ties and then as per Haynes.....reassembly is the reverse of the above.

On that basis the only things that have bothered, but not stopped me, are the lower knuckle pinch bolt and the CV in the hub......
