so i was wondering about the 03 usdm without the acd, the center diff is open correct? but some threds ive read that the center on the open uses viscous coupling. is it open and somehow still useing viscous coupling? or is the viscous coupling for the rear diff?

 

crazy

 

the front diff is open....that is it

 

wheres the viscous coupling? center? rear? both?

 

center and i believe LSD in the rear
