Everet - thanks for the tip on borrowing tools from AutoZone. That will definitely save a few $$$. On another note, I was calling around to get a price for having the bearings pressed on the new diffs, which seems to run about $15/bearing. That's much cheaper than buying a press at Harbor Freight... and spares my garage the additional clutter. One of the machine-guys gave me the name of a local shop that specializes in drive-train work. So I called to get an estimate for the install. Their pricing is much better - $100/end if I bring them the 3rd member to set up, and $300/end if they do the whole job. That's way better than the $1500 one of the local shops quoted. And the guy said they've done lots of Sportages over the years (dealer-warranty work)... and they are familiar with the OBX diffs (though they haven't installed them on a Sportage). So I'm seriously considering going that route - the 3rd member, at least...
