My 7000 has started seeping oil at the oil cooler lines. I plan to replace the 70918980 unions, just curious if there is anything else that might surprise me when I take it apart, or if there are common failures on associated parts? Looks like it should be straightforward, but haven't done this particular application before. Thank you in advance.

The unions are just a rubber crush donut. You might try just tightening them a little more.

hardest part is digging the old ones out of the fittings , some times you can hook them with a pick and screw the nut off of them

If I'm replacing them, I use a small hand held torch to burn them out.
