Big Blue is the loaner tool for removing the delta style links in the rear suspension in P80 Volvos. It supersedes an OEM tool that broke (replaced) twice while out on loaner missions, and was finally lost in the USPS mail system somewhere between Colorado and North Dakota (true story).
Big Blue v2
JDS60R has created a new hydraulic centerpiece to this system. If you feel like thanking someone for something today and don't have anyone in mind, he's a good choice in my humble opinion.

That new piece (Big Blue v2) is now out on its first loaner mission in Vermont.

I've gotten this tool back a few times... barely. Here are two photos of sending, and two photos of receiving (same round trip, not cherry picked).



It shows the beating the box takes. If you borrow this tool, you must pack it like it is the Hope Diamond.
