Looks like your driveshaft CV has failed, if you have a standard metric socket set/spanners and a ball-joint splitter tool wise this is all you should need to change driveshaft, read quite a few threads cover this here on this forum,used them to change mine, it not a difficult job if your confident at the basics, if you search ( top right home page) ‘driveshaft removal/repair’ there should be more detailed info/photos, the gearbox oil needs to be drained before removing driveshaft, its also a lot easier to loosen the driveshaft nut with car on ground before jacking up. Parts wise here’s a link for what your looking for, but this supplier is currently on back order for driveshafts ( also almost doubled in price, 6 months ago they were in stock at €55, bought pair myself), although you can also get the cv’s and gaiters to repair existing driveshaft yourself.

Splitter wise personally find this type

Is a lot kinder to the balljoints than this type, lot less risk of damaging the balljoint rubbers when removing
