kodiak u-joint problems
 

I have 93-95 kodiak (i do not know the exact year) and the u-joint in the front drive shaft are smooth worn out. I have pulled the diff and replaced the u-joint there no problem. however the u-joint for the transfer case is giving me trouble. Is there any way to raplace this u-joint with out removing the transfercase? I thought about driving it out with a hammer and punch inplace but i am afraid that this will damage the bearings or gears in the transfer case. what can I do? thanks
