Dana 44 trac lok question

#1
I am in the process of prepping a 44 from a 2003 TJ Sport to go into my 98, and I have the fluid drained out of the diff. As I was moving it around the shop with tires on each side I noticed that each wheel acts like they are locked together no mater how hard I try I could not get them to move independently. Is this because I have the diff fluid drained out and the trac lok clutches are binding or do I have another issue?
