Going to be swapping the tranny out in my 96 4x4 with 140k on it next weekend and all ready figure on swapping the rear main seal since it will be easy to get to. Is there anything else I should change while it might be conventional while the tranny is out of the way? The one that is going in is a used one with 22k on it. Thanks.

 

you might as well do the u-joints since you are going to have the drive shaft out. If you haven't done them before and they have the original 140K, it's just good measure and do a diff. service while you're at it too.
