Went to a poker run, nothing hard or real nasty. Alot of silt and dust, deep ruts but no real off camber stuff.
I went into a rut and the truck high centered and then I applied brake to engage the truetrac only to hear a snap and have the front end jiggle! NO 4X4 now!!!!
We held the brakes after towing out to see if it would engage and also accelerated spinning rear tires and no spin from front!

Gears are broken in and brand new, 1st real trip off roading. Is there usually warranty on these?
5:29s detroit TT and 33x12.5 MTs. It was not stuck as in wedged or pinched either. I thought the half shafts were the wink link not the 3rd member internals!!! I rocked a hill earlier no issues definently would not have gotten up with open diffs and a few nasty ruts but no bone jarring driving!!!!
Any ideas.
Is there other things that go bump in the night, like the ADD suto 4x4 stuff, the driveshaft spins the half shafts dont!

 

I would assume gears or the Truetrac grenading would make crunching noises. Soundslike your ADD failed to me.

 

sounds like it needs put in the air and some test spinning done.
