You don't need a bearing puller to get the axles out.
You're right about not having to disassemble the suspension - but we already had it apart in my case.
They're not 928 parts, they're Boxster parts. They just happen to have a 928 part number because like a lot of things on the Boxster, they were in the parts bin and used to "cut cost"
. I don't see what the concern is.
