I'll need to cost out the rebuild kit, etc....... but in general.... the kit, a new chain, a new pump and the Omega Machine cost for a) remanufactured case halves and a new mod shift fork.... the capital outlay is what would be nice to have covered in advance.
General costs on average: Rebuild Kit $125 (bearings, seals etc)... New Chain (If wanted) $120.... pump (If wanted) $50 - 75... reman new design fork.... $55 or so, case halves ??? (I am recalling around $250 but my memory is bad...)
I note reman'd ones go for around $850-900 w/o encoder motor replacement. My experience with Reman stuff is that they often only replace the bare essentials.... though some rebuilders are better than others.
I generally carefully clean, inspect and sandblast parts needing it.... then paint where appropriate and reasssemble replacing all wearing parts.... though I start here by admitting I have never rebuild a Transfer case! Just trannies. But I think the skill sets are transferrable....
