Just got the bill, they replaced both birfs (I provided 1, bearings (4) all seals, gaskets and miscellanous items), installed that PITA A/C line - total cost $1100.00. Good work for good money. I have no complaints, they were good guys and will send them more work.
I still can't get the center dif to lock, they thought it was the viscous coupler / transfer case that was screwed up (yesterday's news) and then today they thought it was something with the Engine ECU. I am scratching my head on that one. Not sure about that diagnosis, I am going to get into my service manual and see what it says, I thought for sure that it would be the Locker ECU that would be the issue - this is starting to drive me nuts, if I can't get the center diff to lock, then the other axles will not lock either - and that makes me angry.
