Need assistance. Trying to repair a ct22e dust extractor

[Wipedout]

I’m in the process of replacing the bottom housing of my CT 22E  It’s became badly cracked and since it is integral to suction I order a replacement part.  I am having trouble removing the parts the front casters go in.  Most of the housing plastic is broken around it.  I’m afraid to force it because it could damage parts I’m not replacing.  Any one know or have access to info on how to remove them?  The rest was pretty easy.  Second pic is picture of new pet where they go

I dunno, but if I were you, Id call Festool Service ad talk to a technician. They are pretty good about giving out info for this sort of thing
