I think so. Applying vacuum when switching to 4wd probably won't hurt
anything in the short run but it could draw in contaminants past the
hublocks' O-rings in the long run. If the vacuum line between the frame &
knuckle is removed, you must plug the fittings. Open knuckle fittings will
allow all kinds of moisture and dirt to accumulate in the bearings/hubs.
Open vacuum fittings may confuse the vacuum system.

On my '02, I replaced the knuckle fittings with steel plugs (3/8" NPT IIRC)
and plugged the vacuum fitting on the frame with a sheetmetal screw, and
tossed the vacuum line that was in between.
