I don't get it. Why go through the hassle of trying to find a good t-case, paying the shipping for the t-case, labor for the t-case, etc etc when you can just get the pump rebuilt. IMO its a much easier option, less time consuming, and waaay cheaper. Not to mention that the rebuilt pump will last longer than the original due to updated parts and the pump is sealed off from the elements. Plus the ACD system is a great handling system. To each there own I suppose.

I just couldn't accept being defeated by a stupid gear pump.. In all honesty, and I have been doing pump repairs on a commercial basis, the only reason someone should do it themselves is because of the challenge and/or the fact they really like to work on their car... Sending it out for overhaul makes sense if you just want to fix your car..
If anything, this project resulted in pump repairs being available in the US for what is really a reasonable amount of money..

*update
We've finally seen some warmer weather around here (70) and I took the car out for a spirited drive with lots of turns. First off I tested the pump again with the key on "on" position and the gas pedal down and I heard the pump run for about 5 seconds building pressure. I then took the car out for a 30 minute drive and returned home without any issue!
"Great Success!"
I'll continue to update this thread as time passes...

Is the car drivable with the pump removed, if the ports are plugged? The ACD should act as an open diff just as it has been doing with the non-functional pump, right? Whether I rebuild the pump myself or send it to ACD Tuning, the downtime is an issue.

You can drive normally with no pump... I drove for some 6 months while developing the rebuild kit..

As for downtime, it shouldn't take more than a day/two depending on corrosion to rebuild it yourself. And I don't see the downtime from ACD-Tuning being more than 5-7 days. So It's up to you.
Good luck!

Got 2 bad pumps here. And just ordered a rebuild kit. Cant wait to get my center diff mojo back!
I havent watched the videos yet. But how do you test the solenoid? I only have 1 solenoid. It definitely clicks when applying voltage. Just hoping that isnt my main problem.
Dave, assuming yours is still working well?
