Ok I’m still confused on how our differential works
the transfer case is connected to the tranny than puts power to the wheels via the drive shafts
if the driveshaft is connected to the front and rear differential why don’t all wheels spin ? What is mechanically controlling each wheel ? Or preventing it from getting power ?

 

engine is connected to transmission.
transmission is connected to t-case.
t-case is connected to the front and rear differentials.

the t-case is essentially a third differential, which distributes power front and rear. however, it is not a limited slip design so an axle with no traction will slip and receive all the output from the engine.
the locking t-cases fix 50/50 distribution to the front and rear axles.

 

So the front wheels spin together all the time when they are powered by transfer case ?

 

not necessarily. the front and rear differentials function just like any regular diffs, so one or both wheels may slip. as with the t-case, these diffs are not a limited slip design.
if your underlying question is whether it's possible for all four wheels to be powered at once, even with an unlocked transfer case, then yes, it is. it is a full-time 4wd system. but it's not a managed awd system.

 

My question is there is a drive shaft connected to the front differential that drive shaft is always spinning so both those wheels should be spinning correct ?

 

if a driveshaft is spinning (either front or rear) then i believe that at least one of the wheels on that axle should be spinning. but the driveshaft doesn't have to be spinning.

 

Your saying the front driveshaft sometimes stops spinning while your drinks ?

 

as i said before, EITHER driveshaft can stop spinning if the t-case diverts power to the other one. it's not that the rear axle is the "full-time" axle and the front is "sometimes."

 

So when a axle is spinning say the front axle both front tires are spinning at equal spin

 

Diffs do not know what side is what and do not care.

Open center diff sends power down the path of least resistance. Open front or rear diff sends power to the path of least resistance. You could in theory have 3 tires not moving on 1 spinning.

Only locked diffs will send equal power to both outputs
