Astra H (mk5) cracked power steering rack

Seen a few of these now and although not directly an MOT fail it normaly causes issues with the power steering, often intermittently. Can be difficult to spot if your not looking for it since it's not something you would normaly expect. Defiantly worth an advise in my opinion,

Thats the view of where the column meets the rack looking above the subframe towards the front. There's a small crack just to the left of the corroded bolt in the top of the rack. It can also be visable from the top and looks much worse once you actually get the rack out
