Sounds about it but you should have the CV type rear joint for the front drive shaft so remove the 4 front bolts on the u-joint (front diff end) and push the shaft back and front drops off, then the rear CV has a hit to release internal snap ring so with a block of wood and a 3 lb hammer hit it forward (towards front or diff direction)and the snap ring releases and the rear (transfer case end) pulls off so now you can access the encoder bplts.

Repairdog,
 
Tanx for the reply. From the number of your posts sounds like you've done this before! So here's my question, how often does the encoder just "wiggle out"? Fifty/Fifty? Better, worse?

Transfer Case loss of power now by mkob

I just replaced my transfer case in my 99 GMC Jimmy 4x4. Now when I drive with the A/C on the power is just about zero. I seem to have massive loss of power after the change of the transfer case while my A/C is on only. What can be the cause of this?

My truck is and 2001 GMC SLS Sonoma X-cab:
 
It has the pushbutton 2WD/4HI/4Low buttons on the dash, its a 6cyl with the 4 speed auto trans.
 
My problems is this:
 
Used the 4x4 in HI range this past weekend on my property to pull some old tree limbs to the dump and also at my friends place as well. No off roading or any of that stuff just used it to get up the lawn instead of tearing it all up.
 
Now I'm having issues with the 4x4 disengaging, it goes back into 2 HI but the transfer case is staying locked in. I can move/spin the front shafts but the shaft that goes to/into the transfer case doesn't move or spin at all. It used to move freely when in 2 HI but now it doesn't.
 
All my tests that I have done so far is with the truck sitting on the ground running and in park.
 
I know the 4x4 front shafts are disengaged because the wheels move freely across the pavement. When engaged they do the chopping and sliding event. THIS not my problem its to the transfer case is where its all happening.
 
I am having a lot of drag on the road to the point its eating my gas mileage, there is a slight vibration and I have to lean into it to get it moving.
 
One tranny shop told me it could be some plastic pins or bushings in the transfer case or possibly a fork or two that are going/have gone bad. Without opening it up they cannot tell me what it could be. The price could be a 100 or 200 up to a grand for a used rebuilt transfer case installed.
 
thanks in advance
