Yes sir, that's correct, unlikely, but it could be an axle, and probably the passenger side if it is.
Thanks for adding that.

 

Thank you. I will let you all know when I can get under it. Unfortunately, being that this last weekend was mother's day weekend, I didn't have a chance to work on it. Hopefully I can get to it this weekend.
Would putting the rear end up on jack stands and putting the rig in drive help me narrow down wether it is one of the axles or rear diff? Also, please pardon if this is a stupid question, but why wouldn't the front drive shaft be spinning?

 

Firstly check whether the hi/lo lever is fully engaged in hi ratio?

If the rear driveshaft is turning under real power but not the front driveshaft it may be the centre diff is kaput in the transfer box.

On a 2003 D2 if the front driveshaft is removed or diff is kaput the rear will not drive the truck forward unless you have a CDL due to the centre diff spinning.

If you put all the axles, front and rear, on axle stands the problem, if any, will become evident.

 

The 2003 does not have a locking centre differential (aka transfer case). That means that the output from the engine can go to either one -- or both -- of the driveshafts, depending on the slip situation.
A locking transfer case splits the power so that both driveshafts spin regardless of slip.

 

Lightly apply your emergency brake. That will lock the rear driveshaft. With the rear driveshaft locked, does the front axle begin to turn?

 

Yep, I know unless a CDL has been retrofitted as the 2003 relies solely on TC for traction as mine does. Some fit the earlier or later CDL or even transfer boxes to allow offroading.

In this case I think the OP has an issue within the transfer case which is either the hi/lo linkage not engaging properly or the centre diff planet gears are toast.

 

The current questioner is the one who was asking about why the front driveshaft wouldn't spin. I wasn't explaining this to you, since you probably already know it.
I do like No Doubt's approach to diagnosing the problem.

 

X1 ............ I agree with you, No Doubt's solution should be good.

Apologies for any misunderstanding over my earlier posting.

 

Upon further investigation I found that the emergency brake cable is broken.

 

It is fully engaged in hi. I put the truck up on stands and ran it. i was able to turn the rear wheels by hand while the rig was in drive and reverse and the rear drive shaft was spinning. The front wheels started spinning at around 2000rpm.
