O-ring Fix Question

Hey all - My car has started to develope a minor groan during low speed turning (parking lot type situations), which seems to be pretty certaintly the o-ring issue (still plenty of fluid in the resivoir).

So, what is the downside of waiting a month to fix it? Here in minneapolis, I don't have access to a garage to do the fix myself, nor do I have any torx drivers (unless some kind minneapolis resident wants to volunteer half an hour to help me... *wink*), and I really don't like the idea of taking it to a dealer and trying to convince them that I just want the o-ring replaced.

Am I going to run into any serious issues if I wait till thanksgiving (When I can get back to wisconsin) to do it? I figure I'll probably put on about 500 miles between now and then ... will living with a minor groan for a month lead to substantial issues in 6 months?

Any advice, input, or ways to make girls like me would be helpful...
