Problem with Z steper motor and Z rod brace ,need advice

so today i decided to use auto bed levling to check if my bed is still flat as last time ,and noticed that both points at Bed equation points [60.0, 0.0, -0.409] [60.0, 180.0, -0.517] are off by ~ 0.5mm ,which is to me strange that those 2 are probably the hardest to change by so much , while looking at the Z arm i noticed that the brace that holds the z motor and the Z Smooth Rod in place is cracked!

This would couse the Bed to be off by that much? or atleast make the X-Arm sag down that much.

AND i have found the couse of it

I was using These:

They were working so great , printer was so quiet only thing i could hear was the fan on the hotend. Kinda sad that i wont be able to use them anymore . if someone got any idea of a better design let me know please
The one that comes under the Z motor was probably taking too much of a strain on the brace becouse it was not designed to carry the weight of the printer.
I also notice that the foot is a bit bent at the bottom of the Z profile so will have to print thatone too.

But to the Advice part:

Will i have to disassemble most of the printer to fix this part? or can i just unscrew it and replace and hope nothing shifts?
