can you have 4wd without transfer case?

any alternative to transfer case to power all the wheels? or can we connect a propeller shaft directly to the transmission, then using a locking differential to power the wheels?

    If you have a all wheel drive system it is possible to design into the transmission all of the functions necessary for such a system.

    No. The issue is not as simple as it sounds.

    The transfer case compensates the difference in grip on the highway between the front and rear wheels and the difference between the right and left tires. These are complex issues. using solid lock up will damage components. Early 4 WD vehicles had many problems solved by the transfer case.

    Yes, but it would cause excess load on the engine and wear the tyres faster if it were permanently engaged.

    The transfer case includes another [locking / limited slip] differential that allows the front and rear propshafts to turn at slightly different speeds with different tyre loads and steering angles.

    Take that out and tyres must scrub and wear to some extent.

    So OK if it can be only engaged when needed, such as for off-road vehicles & farm tractors etc., on soil or grass where there is give - but no good on paved roads or for permanent 4WD.
