What did you replace exactly? just the motor or entire unit? is there a fork that goes over a dog clutch in there? kinda sounds like the fork isnt in the collar where it is supposed to be.Its been ages since ive worked on cars full time so i dont know exactly how your set up works.

we replaced the electronic motor and the piece thats attached to it that it has 4 bolts that hold it that bolts it on the the side of the transfer case, and has the plug for the push button and a breather hose attached to it the actual piece we replaced only had one small cog on it but inside there was a larger cog with a couple different sizes on it, the transfer case is still attached to the car so we cant really see whats inside,
