Dodge Repair: transfercase, rear drive shaft, slip yoke

Question
I emailed you previously. Thank you for your fast response. I am have problems finding the transfer case for this vehicle on the auto express site. Also Do you know where a manual for this vehicle that is more detailed than the chilton chrysler full size truck 1989-96?

I just purchased a 1991 4wd dodge dakota ext cab, v-8, auto, so I do not know the history of the vehicle. It shakes after hitting 35mph. We have had it going up to 55 off the ground and can see it loose and shaking at the transfer case. We have changed the U-joint. We are thinking of changing the front yoke for the rear drive shaft(slip yoke, one piece, not bolt, longest one)or possibly the transfer case. What would be you opinion? Thank you very much.
