using 4x4

In your estimation, how many miles of driving on dry pavement does it take before damage is done. Do you know if the effects are cumulative? TIA.

if all four tires are matched, both in size and inflated so that loaded radius was the same all around, in theory, you could drive forever in a straight line on dry pavement with no problems

yes, the effects are 'cumulative'.........torsion in the drive-line accumulates until something goes 'BANG'

So "wet" isn't good enough. I was hoping it would be.

It seems like manual hubs would make the 4x4 practically useless, around here, except in a blizzard or if off-roading. Any other time some roads will be cleared and other areas (roads and parking lots, etc.) will be covered. Lucky me mine has automatic hubs enabling on-the-fly switching. (Unless switching the transfer case to 2WD but leaving the hubs locked is ok ...)

Right.

I have the manual for my BII. It says "don't" but doesn't explain why or the specific limits. A thread in this newsgroup, maybe a month ago, demonstrated why. (someone with an F-[123]50 put it in 4-LO while the wheel was turned as far as it would go on dry pavement)

Thanks for the clarification.

In some instances, on dry pavement, 4X4 Low, low tire pressure and turning the wheel sharply, a tire can also be unseated from the rim by driving the vehicle. This obviously results in an instantaneous flat tire.

It is. Many folks with manual hubs lock the hubs before leaving then switch to

Those will all be OK after the transfer case grenades.

'95 Ford Bronco Auto Front hubs, switched to manuals 3 years ago. I leave 'em locked in about half the time, even in 2WD I haven't had any problems in over 55,000 miles, 4WD works fine when I need it.
