[Sasquatch]

Last night a neighbor asked for help pulling his Ford out of a muddy ravine. So, my winch-equipped Ram was pressed into service. I got the truck halfway down the hillside, and felt the rear end breaking loose and swinging around; now the cab was pointed uphill, and the rear-end was calling the shots. Only then did I realize I didn't have 4WD. The Ram ended up in the ravine, stuck alongside the Ford.

After much inventive winching, I managed to get the Ram back up the hill, made it fast to a big oak tree, and finally pulled the Ford out, sideways.

This morning I traced the vacuum lines under the truck to where they connect with the axle, and everything seems to be okay. I have no way to test for vacuum, so I've just looked for disconnected or damaged lines. I've also checked the shifter linkage at the transfer case and it looks fine.

When I shift into either 4WD H or L, the dash light won't illuminate, and no power is being delivered to the front wheels. I suspect it's a vaccum-related problem, but don't know where to look under the hood to identify the correct line, or see if it's been damaged, kinked, melted-through, or whatever, someplace in the engine comparment. There is a vacuum "T" on the firewall, and I've traced the vacuum hoses which lead there to the servo for the cruise and the HVAC system. They seem to be just fine.

Can anybody tell me where to look to make sure that there isn't a vacuum hose disconnected (the axle control) for the 4x4? I don't have any idea where it should be.

Thanks Much.
