I have checked for vacum leaks and found no leaks.
may just have to take it in to the dealership.
I live in Nebraska so if anybody is close i would be happy to tell you where they are. one is 88 chief 4x4 and the other is 89 pioneer 4x4
the body on the chief is pretty beat up howe ever the poineer looks like some started to modify but never completed. both have front of motors tore down so no chance of starting them. also I can tell you the 89 had a new transfercase installed in 95 acording to the service bill i found.
some of these parts might end up in my garage. thaanks for the welcome and nice to meet you .
