Rough Back on Printed Objects

I've been having some issues with my Anycubic Mega-S recently. The X motor crapped out and had to be replaced, followed by the extruder. I've got those fixed up and they should be all calibrated now. Now my problem seems to be that the back of my prints comes out extremely rough (see picture). I'm using Cura as my slicer. I've tried Slic3r to see if that would solve the problem but that ends up producing a rough back as well. Fan speed it set to 100%. Print speed is 40mm/s. The bottom, top, and all other sides come out smooth like I would expect. It's just the back that look awful. I'm hoping someone might have some insight as to what I can poke at to try and solve this problem as I'd like to get my printed back in working order again.
