I no i have a dana 60 in the front but how could i tell what axle i have in the back or what is common on the four wheel drive, and also when i lock my manual hubs in shouldn't both tires spin?

 

both tires wont spin if you do not have a locker. you most likely have a dana 70 if you have a 250 series or a dana 80 if 350 series.

 

The DANA 80 wasn't available till the '94 and up models.

60 up front, 70 out back (W250 & W350).

The front axle does not have a locker or limited slip differential, therefore, the wheels do not lock together when engaging the hubs.

 

alright i got in to a lil mud this week and i noticed that only two tires would spin at a time and thanks thats good to no and is it supposed to grind when i put it back it to two from four dig my last truck had the push buttom so this is a bit different or is it just it going into neutral

 

on my truck it says on sun viser to do in wile moving and it works for me it grinds if im at a dead stop only

 

o alright that makes alot of since seeing as that has only happens at a dead stop im just glad to no that maybe its alright
my sunvisor is mia at the moment due to headliner modifications

 

i need a new head liner mine rests on my head when i drive bc it sags down haha another dodge common problem

 

if only 2 will spin it means you dont have limited slip (posi trac) making the back lock. then if you are in 4hi only one front will spin, 4lo will lock out both fronts as well

 

i kinda recomend taking the head liner down i did and it nice red paint but i only did it to pin point my flooding cab problem

 

Not quite, 4hi is just high range and 4lo is low. Nothing to do with how mant wheels in the front will pull. The only way to make both pull is with some sort of traction device, weatehr it be LS or a locker. From the factory none of our trucks came with front traction aids.
