Question type: Maintenance & Repair

thinking I narrowed to vac problem. push button on 4x4, an here transfer case engage, so replaced accuator on top of transfer case, that not fix. took battery tray out, an very little vac going to diaphram? Diaphram looks decent shape an can move cable. when running in 4 wheel drive just have little vac an cant believe it enough to move cable. an idea on vac or where to go next?
