    What tranny and t-case do you have? I suspect you have a 203 with a loose chain or a bad diff assembly. You might specify just what you have as for trans and t-case type and maybe post it on the main board also, there's a lot of good troubleshooters there, at least a little more traffic than here.
    Hope this helps
