My 4wd wont work

My 4wd won't work and a friend said I could just turn the vacuum around and it will work. What does this mean? And how do I do it?

You may need to have your driveshaft up front balanced if you've got some vibrations.

Probably just rotted out vacuum lines. 25 years old is way past their expire date.

418 miles on 19 gallons of gas. Can't beat the BBD !

You mean the vacuum motor? That is just gear lube, don't worry about replacing the small amount that leaks out, but I would do a drain and refill of the front and rear diffs just to get a look at the gears and make sure everything looks good.

Put a pan under the diff and pull the bolts. Clean the old gasket/rtv off, install new gasket/rtv. Remove fill plug and fill it up with gear oil till the oil runs out of the plug hole. Also you can pull the shift cover off the axle, pull the clip off the shaft that holds the fork in place (carefull the things are easy to loose) slide the fork over, re-install the clip, slide the shift collar to the engaged position and re-install shift cover.
