Another wheel issue to check for in the 70T bogies is the wheel size. I'm not sure about the Auscision spare bogies, but the 70T type fitted to their RKWF wagon has 36" wheels. This is incorrect for that wagon. Most if not all 70T bogies in Australia have 33" wheels as per the US truck.
I believe Auscision has fitted the larger wheels to keep the bolster height and wagon height the same as the other versions of the AOOX types that have exchange bogies. This is easily fixed. I just put some old K&M (AR KITS) 33" (9.5mm) with 25mm axle wheelsets in the Auscision bogies and put a 020 thou (0.5mm) washer between the body and bogies. However there's no point in spending money on new wheels when you buy complete bogies, unless you can use the originals elsewhere.
It's only 1mm difference in wheel size, but it depends on how much you notice it!
Now, queue the wheel profile debate, I'm bailing out.
