Hi, I am new here

Having 4x4 problems with my 2002 Explorer XLS 4.0 GAS.
During the winter got stuck in the snow and notice that when the wheels spin the light on the dash 4WD-HI lights up, but the wheels don't turn, only driver side rear wheel was spinning ?

Today got all 4 wheel in the air.
When the transmission is on neutral and you turn the shafts by hand only driver side tires rotates?
With engine running on drive all wheels rotates but you can easily stop the rotation of the wheels if you put foot on them?

Is this is normal?
What do you think is the problem?

Thank you very much!

 

What's the axle code ( under AXLE) on the white VCL in the drivers door jamb?

 

The axle code is 45

 

Code 45 is a 3.55 ratio, 'non' limited slip rear set.
D4 would have been Limited Slip..

So, without a clutch/locking type rear end, what you see as far as rotation would be normal.. On a standard rear end, if one wheel rotation is stopped, the opposite side will spin.. Rotating by hand, generally the opposite side will turn in reverse direction.
Limited Slip will turn both axles same direction being their locked..

 

Thanks.
In that case what do you think caused my problem:

 

Help, pleace

AWD still doesn't work.

When the wheels slip on ice the 4WD light comes on, you can hear the 4x4 motor but nothing happened ?
Any ideas what could be the problem?

Thank You.
