Many off-roaders use different ratios front and rear for over drive or under drive. Now these are strictly off-road only rigs though.
I've heard the gearing is slightly different but have never confirmed.
I usually run mine once a month in hi and low

Your saying it's OK to run say 4.10 in the rear and 3.55 in the front?
I would love to see your transfer case after engaging your 4wd. Or what is left of it.

That said, as far as lubricating and what not, the Front Diff, and Transfer Case do spin in 2WD, they may not engage but they do spin and in turn lubricate. The leaving it in 2WD forever and having problems thing, is usually the shifting and activation systems, whether vacuum, manual, or electric, failing or getting seized.

Like I said, it's for dedicated off-roaders and rock crawlers. The ratios aren't as wide spread as you mention.

When you engage 4WD an electromagnetic clutch in the transfer case spins up the front driveline before it's locked in at both hubs.

One way to test is to go start your truck. Jack the front end and spin the wheel. Nothing should move. If it does your iwe's are not working.
