70,000 is a minor service so of the top of my head;
Oil, oil filter, Trans fluid (probably hasn't ever been done if you haven't done it yet), check your other fluid levels (replace if necessary) and for general wear and tear that could be an issue.
Maybe bleed your brakes and put in some fresh DOT 4 fluid if they have not been done to your knowledge.
Check power steering fluid for colour (shouldn't be black) and change if necessary.
Coolant, diff, ATTESSA etc should be changed around 90,000
I do feel that I am missing something though....
