project update
We have been racking our brains on how to lock the viscous coupling. There are a few ideas out there on how to make this possible but the expense is making it cost prohibitive. To make matters worse I don't know if the front output shaft is strong enough to handle being fully locked. But as the old saying goes when the going gets tough the tough get going. So we built a jig, welded the viscous coupling in the correct locked position and installed it in the transfer case.
By doing this we will be able to find out if the front output shaft is strong enough to handle the load put on it when the transfercase is locked. If it doesn't explode we will continue to look for viable options to lock the T case. The best way to show that the transfer case is locked on a Borg-Warner box is to pull the front driveshaft and see if the truck will still move, and thats exactly what we did in this video.

Your first take on the video maybe just a yahoo having fun in the snow, but when you really look at it our P38 is spinning the rear tires while the front tires remain stationary. This means the transfercase is locked and all the power is going to the rear output shaft without causing an explosion. I'm pretty confident that the rear will hold up okay. We have been driving the truck around as a rearwheel drive unit for about a week without any side effects.

The last thing I read was Justin's post about drivetrain sounds, then saw the photos.

do they come with poly bushings? That's what the ones look like for the Disco.

so Justin... How do you guys want to engage the lock?

Electric or Air. Right Now the lock unlock mechanism is the front driveshaft

I'd vote for electric

The problem is that there isn't much that will fit, we've done the research already.Chevy t cases have a center rear out put. Lt230 would need to be installed upside down and all that.
I greased my driveshafts this morning and noticed they needed it from when I was messing with the driveshafts during the 5 speed install

I wish the lt230 would fit.

Me too... But if you get that Borg Warner to lock and not self destruct , you yourself got a market there.

I don't know anything about that.
