there's nothing to handle the "big" torque on the xfer case...that's the dandy I had in mind....have seen trouble stemming from road debris on 4wd systems a couple o times~

just had a same problem with my 01 S10. Was simply the vacuum hose on the drivers side fender. Connected it and it went right in.
