Thanks for all the advise above, I found it helpful and checked out the NASIOC website/forum too.
I have tried to educate myself on what my best options are for replacing the Propshaft/driveshaft (depending on who you talk to). I even had the salvage yard call Subaru to confirm the part they can get is the part I need. So it looks like my 2 options are:
buy new -$770.00 plus install estimated at $100.00, 1 yr warrenty
buy used $200.00 plus install estimated at $100.00, 90 day warrenty
the used one already has 60,000-90,000 miles on it.
my car currently is at 179,000 miles, 1 owner, well maintained.
If it was your car, what would you do?
