Sloppy Z axis (Gantry) on 2nd hand unit

Ok to begin thanks to those that helped me previous with this on a real bad transport… I have been learning the CNC and found that the motor mount has slop when milling because the all the bearings are not in contact with the 3/4 in conduit 100% of the time and I am getting lateral movement because of this. Is this normal? Is there a way to adjust the position of the roller bearings or do I need to have the parts reprinted? If I need them reprinted which part names do I need? I am going to extend the size a little an now is the time to do it anyways.

any ideas would be appreciated.

Some pictures of which bearings are loose would help.

pics showing actual slop are not ease , but attached… The bearing I am having issues with are the ones aon the XY part (red part in the link you gave) and I only have about 1/8" but it is enough that it is causing me to brake bits (.75mm endmill)
