so anyone who can help point me in the right direction on this gets my undying gratitude. and maybe some bacon. my truck is a 2002 s10 pickup, 4x4, with the 4.3L v6 and an automatic transmission and electronically controlled transfer case and factory optioned lockers front and rear. as far as i know, everything is still stock. (i bought it used.) it has not been lifted, and the tires are oem sized. i got stuck in some mud recently, and my buddy that pulled me out pointed out that my front tires weren't driving. i put it up on jackstands on the frame, started it, and shifted into every setting on the tcase. 2 hi works just fine, 4 hi drives the rear tires and front drive shaft, and 4 lo drives and locks the rear and turns the front driveshaft. so what is wrong with my front differential? there is a cable that runs into the front differential and then up towards the right front corner of the truck. does this cable serve to mate the differential to the spinning driveshaft in some way? has anyone had this trouble before? i'm really hoping to get this solved soon. its sucks to get the lower fuel economy from having a 4x4 without the extra capabilities of a 4x4. please send your wisdom my way, and i swear i'll be your bestest buddy forever.
