Advice - Selling vs Fixing

[LTdesign]

I have an '08 Outback Limited. 205k miles. Lots of new parts & recent work done on it (see list below).
Looking for some advice here. Recently started re-paying student loans and may possibly have some upcoming medical bills TBD (MRI scheduled for tomorrow). Feeling a little overwhelmed financially atm.
The front differential blew almost a year ago (February '24). Originally, I had thought about fixing it. Usually I do my own work, but this repair is not within my skillset/capabilities, time, or space constraints. I ended up buying a 4Runner which I now think wasn't the best move, but that's another story. Right now, I have it listed on FB Marketplace, OfferUp, and Craigslist, asking $2000 OBO as-is. Question is - do y'all think this is the best way to handle this? Should I seek out a transmission shop instead and go ahead with the diff. replacement? I was quoted about $2500 from one shop. This would cut pretty severely into my savings acct. Pictures attached for reference.
Work done / extra & new parts: Tons of new parts, I think this is everything...:

For me...the answer is almost always fix and keep. Can u sell the Foreskinner? The OB got a good 5 years and 100k miles left most likely. By then you hopefully in a better financial situation. If you dont fix what is your next best option? Personally i am not in a situation to save for a new car..and despise car payments.
