Visit at least two more shops, including a clutch and drive line shop. Have them inspect and diagnose. Say nothing of previous inspections/diagnostics. IMO, driving with the front axle is very short term solution, as in a few hundred miles or less.
If in fact, your rear differential needs a $600 - $1,000 rebuild, your most inexpensive solution is to buy a complete axle and install it yourself. You can swap axles in your driveway with simple hand tools in about 4-6 hours.
