Hey guys I have a 91 cherokee I broke a shiftfork the other day on the vacuum disconnect I just replaced the shiftfork and now I have a clunking noise in the frontend is it possible that I could have tore the splines out of the shift collar I checked the u joints and they're all tight

 

prolly have a chunk or 2 still bouncing around in there.....

 

The clunking noise only happens when its in 4 wheel and before I fixed the shift fork I had the transfer in 4 lo and there was no noise was wondering if it could maybe the chain in the t case under a load skipping teeth
