U joints

Any one have any knowledge for the U joints for the 4wd shaft on T100 or similar chassis, does the front sway bar need to be removed? Also the rear crossmember for transfer case is anything holding transfer case up? Almost removed all 8 bolts holding and I realized there doesn't seem to be anything holding transfer case up, so I'll assume I need a jack or jack stands for it??? Any knowledge greatly appreciated

 

Ya kinda started out right in the middle of things here perhaps a little back ground of what your doing will help everyone understand what you are setting out to do because from the post we can only guess at things so be generous on the details and I'm sure that there are folks here that will know.

 

I just changed our all u joint y on main drive line, now I'm wanting to change out ones for the 4wd shaft, ther is a crossmember what looks to be like it is supporting the 4wd transfer case at the bottom, what I'm wanting to know is there any anything else holding the TC from above? The CM has 4 17mm bolts at each end I was down to one bolt each side when I realized the TC might fall down, so I'm assuming I need to support it with a jack??? And at the front of the 4wd shaft ther is a front sway bar, does this need to be removed?

 

Anyone?
